Welcome to the next generation of protective communication. IMPORTANT Please read, understand, and follow all safety information in these instructions prior to use. Retain these instructions for future reference. For additional information or any questions, contact 3M Technical Service (contact information listed on the last page).

! WARNING This hearing protector helps reduce exposure to hazardous noise and other loud sounds. Misuse or failure to wear hearing protection at all times when exposed to hazardous noise may result in hearing loss or injury. For proper use, see supervisor, User Instructions or call 3M Technical Service. If your hearing seems dulled or you hear a ringing or buzzing during or after any noise exposure (including gunfire), or for any other reason you suspect a hearing problem, leave the noisy environment immediately and consult a medical professional and/or your supervisor. Failure to follow these instructions may result in serious injury or death:

Listening to music or other audio communication may reduce your situational awareness and ability to hear warning signals. Stay alert and adjust the audio volume to the lowest acceptable level. Failure to follow these instructions may reduce the protection provided by the earmuff and may result in hearing loss:

a. 3M strongly recommends individual fit testing of hearing protectors. If the NRR or SNR is used to estimate typical workplace protection, 3M recommends that the noise reduction value be reduced by 50% or in accordance with applicable regulations. b. Ensure the hearing protector is properly selected, fit, adjusted, and maintained. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit. c. Inspect the hearing protector before each use. If damaged, select an undamaged hearing protector or avoid the noisy environment. d. When additional personal protective equipment is necessary (e.g. safety glasses, respirators, etc.), select flexible, low profile temples or straps to minimize interference with the earmuff cushion. Remove all other unnecessary articles (e.g. hair, hats, jewelry, headphones, hygiene covers, etc.) that could interfere with the seal of the earmuff cushion and reduce the protection of the earmuff. e. Do not bend or reshape the headband, and ensure there is adequate force to hold the earmuffs firmly in place. f. Earmuffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for cracking and leakage, for example. When used regularly, replace the ear cushions and foam liners at least twice a year to maintain consistent protection, hygiene, and comfort. g. The output of the electrical audio circuit of this hearing protector may exceed the daily limit sound level. Adjust the audio volume to the lowest acceptable level. CAUTION:

Risk of explosion if battery is replaced by an incorrect type. NOTE When worn according to the User Instructions, this hearing protector helps reduce exposure to both continuous noises, such as industrial noises and noises from vehicles and aircraft, as well as very loud impulse noises, such as gunfire. It is difficult to predict the required and/or actual hearing protection obtained during exposure to impulse noises. For gunfire, the weapon type, number of rounds fired, proper selection, fit and use of hearing protection, proper care of hearing protection, and other variables will impact performance. To learn more about hearing protection for impulse noise, visit www.3M.com/

hearing. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire (wording required by EPA).

*LiteCom Plus Hard Hat Attached Model MT7H7P3E4610-NA was tested with 3M PELTOR Hard Hat Model G3001. 3M strongly recommends fit testing of hearing protectors. The NRR is calculated from laboratory-based attenuation data. Research suggests that many users will receive less noise reduction than indicated by the NRR. If NRR is used to estimate typical workplace protection, 3M recommends that it be reduced by 50% or in accordance with applicable regulations. The Noise Reduction Rating (NRR) was obtained with the device powered off. The level of noise entering a persons ear, when hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Example 1. The environmental noise level as measured at the ear is 92 dBA. 2. The NRR is 25 decibels (dB). 3. The level of noise entering the ear is approximately equal to 67 dB(A). CAUTION: For noise environments dominated by frequencies below 500 Hz the C-weighted environmental noise level should be used. 5 EN COMPONENTS A.

No No No No No No No Yes Yes Yes Yes Yes Yes Yes Yes PTT (Push-to-talk) button Press and hold the PTT button (A:15 for built-in two-way radio or A:16 for auxiliary two-way radio) to open the two-way radio channel and then speak in to the microphone. NOTE: When pushing the PTT button, the headset will always transmit a signal regardless of the BCLO setting. VOX (voice-operated transmission) VOX is a hands-free substitute for the push-to-talk (PTT) button. With VOX, you simply speak into the microphone to open the channel. The VOX setting defines the acoustic threshold that activates the radio transmission. Higher settings are appropriate for louder environments. To adjust the sensitivity of VOX, press the (+) button (A:10) or () button (A:11) when on the VOX menu setting. You can choose between five levels or switch this function off. To turn the VOX function on and off, press the PTT button twice. Alternatively, when on the VOX setting in the menu, press the () button for two seconds to turn VOX off. Press the (+) button to switch this function back on. If VOX is off, the PTT button must be used to transmit. NOTE: By default, the Busy Channel Lock Out (BCLO) function will prevent VOX operation if the channel is occupied with other transmission (busy) and you will hear an audible tone to indicate the blocked transmission. These settings can be adjusted in the setup menu. NOTE: To effectively use VOX, the speech microphone (A:8) must be very close to your mouth, less than 3 mm (1/8 inch). You will hear your voice in the headset when the radio is transmitting. Sub menu The sub menu is accessed by pressing the (+) button (A:11) and () button (A:12) at the same time for one second and contains the features and settings listed below. To return to the main menu, press and hold the (+) button and () button at the same time again or wait 10 seconds and the headset will automatically return to the main menu. 8 EN Squelch (hiss reduction) The Squelch feature will reduce the distracting radio hiss or static noise. You can choose between five squelch levels by pressing the (+) button (A:11) or () button (A:12). A higher squelch level will further reduce the noise, but will also reduce your range of reception. To switch this function off, press the () button for two seconds. Press the (+) button to switch this function back on. Sub channel (selective squelch) The Sub channel feature can be used to set up multiple private groups within a single channel. When the sub channel feature is active, an inaudible code will be transmitted with the speech and only the receivers with the same sub channel setting will hear the transmission. However, if anybody is transmitting on the channel, all sub-channels will be busy during that time. If the sub channel feature is switched off, all communication on a channel will be heard. Press the (+) button

(A:11) or () button (A:12) to select the sub channel. The LiteCom Plus headset supports Continuous Tone Coded Squelch System (CTCSS) and Digital Coded System (DCS) for a total of 121 frequencies/codes (see table below for sub channel #

NOTE: Do NOT immerse the hearing protector in water. If the hearing protector gets wet from rain or sweat, turn the earmuffs outwards, remove the ear cushions and foam liners, and allow to dry before reassembly. The ear cushions and foam liners may deteriorate with use and should be examined at regular intervals for cracking or other damage. When used regularly, 3M recommends replacing the foam liners and ear cushions at least twice a year to maintain consistent attenuation, hygiene, and comfort. If an ear cushion is damaged, it should be replaced. See Spare Parts Section below. REMOVING AND REPLACING THE EAR CUSHIONS E:1 To remove the ear cushion, slide your fingers under the edge of the ear cushion and firmly pull straight out. E:2 Replace the foam liners. E:3 Fit one side of the ear cushion into the groove of the earcup and then press on the opposite side until ear cushion snaps in place. E:1 E:2 E:3 CHARGING THE BATTERY The LiteCom Plus headset uses the ACK081 rechargeable battery, which can be charged using the included AL2AI charging cable and the FR08 Power Supply. The ACK081 battery can be recharged either when connected or disconnected from the headset. To remove the ACK081 battery, first ensure the headset is powered off, then insert your finger under the edge of the battery clamp and pull up and outwards. A low battery level is indicated by a voice message of low battery, repeated every 5 minutes. If the batteries are not recharged, a battery empty message will sound and the unit will automatically switch off. If interference increases or the sound level becomes weak, try recharging the batteries. NOTE: Remove the batteries when storing the headset for extended periods of time. REPLACING THE HARD HAT ATTACHMENT PLATE For proper fitting on different industrial safety hard hats, the hard hat attachment plate may need to be replaced. The headset comes assembled with P3E hard hat attachment. Plates for P3K hard hat attachment assembly are also included in the box. A screwdriver is needed to replace the hard hat attach-

ment plate. F:1 Loosen the screw holding the plate and remove the plate.

La inobservancia de estas instrucciones puede reducir la proteccin proporcionada por las orejeras y comporta riesgo de prdida auditiva:

a. 3M recomienda encarecidamente probar el encaje de los protectores auditivos. Si se usa NRR o SNR para estimar una proteccin tpica en lugar de trabajo, 3M recomienda bajar el valor de reduccin en un 50% o segn la normativa aplicable. b. Comprobar que el protector auditivo se selecciona, encaja, ajusta y mantiene correctamente. IUn encaje inadecuado de este aparato reducir su eficacia atenuadora de ruido. Consultar las instrucciones adjuntas para un encaje adecuado. c. Inspeccionar el producto cuidadosamente antes de cada uso. Si el protector auditivo se daa, elegir un protector auditivo en perfecto estado o evitar el entorno ruidoso. d. Cuando es necesario usar equipo de proteccin individual adicional (p.ej., gafas protectoras, mscaras respiratorias, etc.), usar patillas o cintas flexibles de perfil bajo para minimizar la interferencia con la almohadilla de la orejera. Quitar todos los artculos innecesarios (p.ej., cabello, sombrero, joyas, auriculares, cubiertas higinicas, etc.) que puedan interferir con el sello de la almohadilla de la orejera y reducir la proteccin de la misma. e. No doblar ni cambiar la forma de la diadema, y asegurar que haya fuerza suficiente para retener la orejera firmemente colocada. f. La orejera, y especialmente las almohadillas, pueden deteriorarse con el uso y deben revisarse con frecuencia para ver si tienen grietas y fugas, por ejemplo. Cuando la orejera se usa regularmente, cambiar los revestimientos de espuma y las almohadillas por lo menos dos veces al ao para mantener una atenuacin, higiene y confort constantes. g. La salida del circuito de audio elctrico de este protector auditivo puede exceder el nivel sonoro lmite diario. Regular el volumen de audio al nivel ms bajo aceptable. PRECAUCIN:

Riesgo de explosin si la batera se sustituye por una de tipo incorrecto. NOTA:

Este protector auditivo, cuando se usa segn este manual de instrucciones, ayuda a reducir la exposicin a ruidos continuos como ruidos industriales, ruido de vehculos y aviones y ruidos impulsivos fuertes como disparos. Es difcil pronosticar la proteccin auditiva necesaria y/o real obtenida durante la exposicin a ruidos impulsivos. Para el ruido de disparo, afectan al rendimiento factores como el tipo de arma, el nmero de tiros, la seleccin correcta, la colocacin y uso de protector auditivo, el cuidado adecuado del protector auditivo y otras variables. Para ms informacin sobre proteccin auditiva contra ruido impulsivo, visitar www.3M.com/hearing. Aunque es posible recomendar protectores auditivos para proteccin contra los efectos dainos del ruido impulsivo, el nivel de reduccin de ruido (NRR) se basa en la atenuacin del ruido continuo y podra no ser un indicador preciso de la proteccin posible contra ruido impulsivo como, por ejemplo, disparos de armas de fuego (redaccin requerida por EPA). La batera no se debe cargar si la temperatura ambiente sobrepasa 45 C (113 F). Intervalo de temperaturas de funcionamiento: entre 20 C (-4 F) y 55 C (131 F) Intervalo de temperaturas de almacenaje: entre -40C (-40F) y 55 C (131 F) 14 ES ATENUACIN EN LABORATORIO MT7H7A4610-NA ANSI S3.19-1974 NRR Frecuencia de prueba (Hz) 1.000 2.000 3.150 4.000 6.300 8.000 125 250 500 Atenuacin media (dB) 17,8 23,0 32,1 36,2 Desviacin normal (dB) 4,4 3,2 2,8 3,0 35,1 2,4 39,0 3,8 38,7 3,0 38,3 3,5 36,5 3,9 25 MT7H7B4610-NA ANSI S3.19-1974 NRR Frecuencia de prueba (Hz) 2.000 3.150 1.000 4.000 6.300 8.000 125 250 500 Atenuacin media (dB) 18,9 25,9 35,2 37,0 Desviacin normal (dB) 5,2 3,2 3,3 2,9 34,9 2,5 40,6 3,6 39,9 3,0 39,7 2,3 39,7 2,5 26 MT7H7P3E4610-NA*

*El modelo para fijar en casco de seguridad de LiteCom Plus, MT7H7P3E4610-NA, se ha probado con el modelo de casco de seguridad 3M PELTOR G3001. 3M recomienda encarecidamente probar el encaje de los protectores auditivos. El valor de reduccin de ruido (NRR) se calcula sobre la base de datos de atenuacin en laboratorio. La investigacin sugiere que muchos usuarios recibirn una reduccin de ruido menor que la indicada por NRR. Si se usa NRR para estimar una proteccin tpica en lugar de trabajo, 3M recomienda reducir NRR en un 50% o segn la normativa aplicable. El valor de reduccin de ruido (NRR) se ha obtenido con el aparato apagado. El nivel de ruido que entra en el odo de una persona cuando se usa un protector auditivo tal como est indicado es muy aproximado a la diferencia entre el nivel de ruido ambiental con ponderacin A y el valor NRR. Ejemplo:

1. El nivel de ruido ambiental medido en el odo es de 92 dB(A). 2. El valor NRR es de 25 decibelios (dB). 3. El nivel de ruido que entra en el odo es aproximadamente igual a 67 dB(A). PRECAUCIN: Para entornos ruidosos en que predominan frecuencias de menos de 500 Hz debera usarse el nivel de ruido ambiental con ponderacin C. 15 ES COMPONENTES A.

All data per ANSI S3.19-1974. CSA Class A A A The NRR calculated from these laboratory-based attenuation data is 25. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the fitting instructions for proper fit. The level of noise entering a persons ear. when a hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Example:

1. The environmental noise level as measured at the ear is 92 dBA. 2. The NRR is 25 decibels (dB). 3. The level of noise entering the ear is approximately equal to 67 dBA. Caution: For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the noise reduction rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the fitting instructions for proper fit. 4

FCC Regulations and Licensing Application Information 6.1 FCC Warning This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) this device must accept any interference received, including interference that may cause undesired operation. Any Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Before any station transmits on any channel authorized in the GMRS from an point (a geographical location) within or over the territorial limits of any area where radio services are regulated by the FCC, the responsible party must obtain a license (a written authorization from the FCC for a GMRS system . 6.2 FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Do not transmit for more than 50% of the total transceiver use time; transmitting over 50% of the total use time may exceed the limits in accordance to the FCC RF exposure requirements. Nominal transceiver operation is 5%

transmission time, 5% reception time and 90% stand-by time. 6.3 IC Warning This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:

(1)This device may not cause interference and

(2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that, the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. 7.CAUTION When set to full gain the earphones can produce an equivalent sound level of up to 87dB(A). This is considered safe for daily 8-hours use, as long as the time spent in receiving mode does not exceed 2,5 hours. If the time spent listening to the earphones exceeds 2,5 hours per day the gain setting must be reduced below maximum. One step below maximum gain produces an equi-

valent sound level of 82 dB(A), considered safe even if used in the listen mode, in noise, for a full 8-hours day.

Federal Communications Commission DA 13-431 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended WT Docket No. 99-87 Promotion of Spectrum Efficient Technologies on Certain Part 90 Frequencies RM-9332

) ORDER Adopted: March 15, 2013 Released: March 18, 2013 By the Chief, Wireless Telecommunications Bureau, Chief, Public Safety and Homeland Security Bureau, and Chief, Office of Engineering and Technology:

1. Introduction. In this Order, we grant in part and deny in part a Petition to Delay Indefinitely Implementation of Section 90.203(j)(5) of the Commissions Rules filed by Ritron, Inc.

(Ritron) on September 21, 2012.1 Pursuant to Section 90.203(j)(5) of the Commissions rules, the Commission no longer accepts applications for certification of Part 90 private land mobile radio (PLMR) equipment in the 150-174 MHz and 450-512 MHz bands that cannot operate in a 6.25 kHz mode or with equivalent efficiency.2 Ritron requests that implementation of this requirement be delayed indefinitely. We conclude that the requirement should be waived only until January 1, 2015. 2. Background. In 1995, the Commission adopted rule changes to promote the efficient use of the PLMR service and facilitate the introduction of advanced technologies.3 To promote the transition to a more efficient narrowband channel plan, the Commission provided, inter alia, that only increasingly efficient equipment would be approved.4 The Commission did not set a date after which it would no longer approve equipment with a wideband (25 kHz) mode, or after which such equipment could no longer be manufactured or used.5 The Commission contemplated that, as systems reached the end of their service life and new radios were needed, users would migrate to the narrower bandwidth multi-mode radios in order to avoid the adjacent-channel interference that could occur from systems using the adjacent narrowband channels.6 3. Subsequently, the Commission determined that the 1995 rules failed to provide adequate incentive to realize the Commissions spectrum efficiency goals in these bands, and stronger measures 1 See Petition to Delay Indefinitely Implementation Section 90.203(j)(5) of the Commissions Rules (filed Sept. 21, 2012) (Petition). 2 See 47 C.F.R. 90.203(j)(5). 3 See Replacement of Part 90 by Part 88 to Revise the Private Land Mobile Radio Services and Modify the Policies Governing Them, Report and Order and Further Notice of Proposed Rule Making, PR Docket No. 92-235, 10 FCC Rcd 10076, 10077 1 (1995). 4 Id. at 10081 7. 5 Id. at 10100 40. 6 Id. Federal Communications Commission DA 13-431 would be required to bring about a timely transition to narrowband technology.7 The Commission therefore amended the rules to provide that, by January 1, 2013, Industrial/Business and Public Safety Radio Pool licensees in the 150-174 MHz and 421-512 MHz bands must migrate to 12.5 kHz channel bandwidth or utilize a technology that achieves equivalent efficiency.8 4. The Commission also adopted interim deadlines to facilitate this transition to narrowband technology. Among other rules, the Commission provided that, beginning January 1, 2011, it would no longer accept applications for certification of equipment that cannot operate in 6.25 kHz mode or with equivalent efficiency.9 In 2010, the Commission temporarily waived this requirement until January 1, 2013,10 but stated, If 6.25 kHz standards still are not in place at that date, interested parties may request a further extension.11 5. Ritron, a manufacturer of wireless products, contends that standards for 6.25 kHz technology are not yet in place and that other issues exist that justify delaying implementation of mandatory 6.25 kHz certification by manufacturers. Ritron states that no one 6.25 kHz equipment standard exists and that, in the Industrial/Business sector of the market, two incompatible and proprietary technologies have emerged.12 It also argues that 6.25 kHz equipment is still unduly expensive.13 Finally, Ritron asserts that using the equipment authorization process to facilitate the transition to narrowband technology has been largely unsuccessful.14 It concludes that the implementation of Section 90.203(j)(5) should be delayed until (a) a real need has been established for additional PLMR frequencies beyond those created by the transition to 12.5 kHz channels; (b) the benefits of 6.25 kHz outweigh the associated research and development, manufacturing, and product costs; and (c) a standard has emerged for a more cost-effective voice compressor/decompressor (vocoder).15 6. The Wireless Telecommunications Bureau, Public Safety and Homeland Security Bureau and the Office of Engineering and Technology sought comment on Ritrons request.16 We asked commenters to address whether the public interest would be served by further delaying implementation of 7 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Second Report and Order and Second Further Notice of Proposed Rulemaking, WT Docket No. 99-87, 18 FCC Rcd 3034, 3038 12

(2003). 8 See 47 C.F.R. 90.209(b)(5). The January 1, 2013 deadline for converting to 12.5 kHz technology has been waived for licensees in the 470-512 MHz segment of the UHF band (the T-Band). See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Order, WT Docket No. 99-87, 27 FCC Rcd 4213

Ritron argues that the equipment authorization process does not motivate licensees to adopt narrowband technology because they gain no advantage from doing so. 15 See id. 16 See Wireless Telecommunications Bureau, Public Safety and Homeland Security Bureau and Office of Engineering and Technology Seek Comment on Petition to Delay Indefinitely Implementation of Section 90.203(j)(5) of the Commissions Rules, Public Notice, WT Docket No. 99-87, 27 FCC Rcd 14893

(WTB/PSHSB/OET 2012). 2 Federal Communications Commission DA 13-431 the requirement that applications for equipment certification demonstrate capability to operate on 6.25 kHz channel bandwidths or with equivalent efficiency, and whether any additional waiver should be indefinite or tied to a specific date. Six parties filed comments or reply comments. Commenters generally favor temporarily or permanently delaying the implementation of Section 90.203(j)(5). 7. Discussion. We deny Ritrons request that we indefinitely delay implementation of mandatory 6.25 kHz certification by manufacturers, but we conclude that a temporary waiver is appropriate. As noted above, Ritron argues that the benefits of 6.25 kHz operation do not outweigh the associated research and development, manufacturing, and product costs, and that current 6.25 kHz vocoders are not cost-effective. We do not find this persuasive, for Ritron does not explain why, if this is the case, many manufacturers (including Ritron)17 have been able to develop equipment that is capable of operating in 6.25 kHz mode.18 Ritron has also not quantified its claim that 6.25 kHz-capable radios are disproportionately more costly than non 6.25 kHz-capable radios nor balanced any increased cost for 6.25 kHz-capable radios against the spectrum efficiency benefits inherent in 6.25 kHz technology. 8. Ritron also argues that no need has been established for additional PLMR frequencies beyond those created by the transition to 12.5 kHz technology. The Commission has already concluded, however, that 12.5 kHz technology is only a transitional step in the eventual migration to 6.25 kHz technology,19 and has indicated that it will in the future establish a timeline for PLMR licensees to migrate.20 Pursuant to the 1995 rules, the Commission in 1997 stopped accepting applications for certification of Part 90 PLMR equipment in the 150-174 MHz and 450-512 MHz bands that could not operate in a 12.5 kHz mode or with equivalent efficiency.21 When the Commission subsequently enacted a deadline for mandatory migration to 12.5 kHz technology, it noted that the wide availability of 12.5 kHz-capable equipment resulting from the 12.5 kHz requirement for new equipment certifications in the preceding years would facilitate licensees migration.22 Just as the timeline for mandatory migration to 12.5 kHz technology was predicated on 12.5 kHz-capable equipment already being available, we expect the availability of 6.25 kHz-capable equipment to be an important prerequisite to the adoption of a timeline for mandatory migration to 6.25 kHz technology.23 Ritron provides no basis for us to abandon the Commissions plan. 9. Finally, Ritron argues that implementation of the requirement that applications for equipment certification demonstrate 6.25 kHz capability should be delayed until a single industry-wide standard emerges in the marketplace. We disagree. As Ritron notes, manufacturers have developed multiple standards, as the Commission anticipated when it suggested in 2010 that it would entertain a request for a further extension of the deadline if 6.25 kHz standards had not been developed by 2013.24 Indeed, the Commission has never suggested that it foresees or will require adoption of a single 17 See, e.g., FCC ID # AIERIT28-150. 18 See Comments of Icom America, Inc. at 3-4. 19 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Fourth Memorandum Opinion and Order, WT Docket No. 99-87, 23 FCC Rcd 8042, 8044-45 8 (2008). 20 See Third Report and Order, 22 FCC Rcd at 6088-89 10-11. 21 See 47 C.F.R. 90.203(j)(3). 22 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Third Memorandum Opinion and Order, Third Further Notice of Proposed Rule Making and Order, WT Docket No. 99-

87, 19 FCC Rcd 25045, 25056-57 25 (2004) (Third MO&O). 23 See Third Report and Order, 22 FCC Rcd at 6088-89 11. 24 See Order, 25 FCC Rcd at 8866 n.41. 3 Federal Communications Commission DA 13-431 mandatory standard, and we do not expect such a development to occur in the Industrial/Business sector.25 10. We do, however, anticipate the development of a single standard in the Public Safety sector, for which the ANSI 102 Project 25 Phase II standard (P25 Phase II) is being completed.26 This standard will help ensure that public safety radios are interoperable, a critical goal of public safety communications.27 We find that it is in the public interest to allow standards bodies to complete the P25 Phase II standard before imposing the requirement that radios be capable of operating on 6.25 kHz channels, and extend the implementation of Section 90.203(j)(5) until January 1, 2015. 11. When the Commission extended the implementation of mandatory 6.25 kHz certification by manufacturers from 2011 to 2013, it noted commenters arguments that requiring applications for equipment certification to specify 6.25 kHz capability as of January 1, 2011 would increase equipment cost, and that compelling the purchase of more expensive equipment that may need to be replaced once a public safety standard was developed would burden public safety resources.28 In addition, proliferation of 6.25 kHz equipment that is incompatible with the P25 Phase II standard could undermine interoperability,29 which would be contrary to the public interest and the Commissions goals.30 Therefore, we conclude that a temporary extension of the waiver of the requirement that applications for equipment certification demonstrate 6.25 kHz capability, to allow completion of the ANSI 102 Project 25 Phase II standard, is appropriate. 12. We note that as of January 1, 2015, the Commission will no longer accept applications for certification of Public Safety equipment in the 700 MHz band that cannot operate in a 6.25 kHz mode or with equivalent efficiency.31 We therefore grant a waiver until that date, rather than the indefinite waiver requested by Ritron. Specifically, we grant a waiver of the requirement in Section 90.203(j)(4)(iii)-(iv) and (j)(5) that VHF and UHF equipment operating on 25 kHz channels be capable of operating with the equivalent of four voice channels.32 We will continue to accept applications for certification of equipment operating on 25 kHz channels if it is capable of operating with two voice channels until January 1, 2015.33 In addition, we waive the requirement in Section 90.203(j)(4)(ii) that 25 Ritron itself observes that a consolidated standard may never exist in the Industrial/Business sector. See Petition at 2. 26 See Third MO&O, 19 FCC Rcd at 25060 37. 27 See The Development of Operational, Technical and Spectrum Requirements for Meeting Federal, State and Local Public Safety Communications Requirements Through the Year 2010, Fourth Notice of Proposed Rule Making, WT Docket No. 96-86, 15 FCC Rcd 16899, 16916 42 (2000). 28 See Order, 25 FCC Rcd at 8865 11. 29 See Comments of Association of Public Safety Communications Officials-International, Inc. at 1-2. 30 See Order, 25 FCC Rcd at 8864 8 (When the Commission adopted the 2011 deadlines, it specifically stated that the narrowbanding schedule was designed to avoid complicating efforts to establish public safety interoperability.)

(citing Third MO&O, 19 FCC Rcd at 25022 22). The Commission places great importance on facilitating public safety interoperability. See, e.g., The Development of Operational, Technical and Spectrum Requirements For Meeting Federal, State and Local Public Safety Agency Communication Requirements Through the Year 2010, Fourth Memorandum Opinion and Order, PR Docket No. 96-86, 17 FCC Rcd 4736, 4746 24 (2002). 31 See 47 C.F.R. 90.203(m). 32 See id. 90.203(j)(4)(iv), (j)(5). We hereby clarify that we do not waive the requirement that equipment with a channel bandwidth of more than 6.25 kHz that is capable of transmitting data must be capable of supporting a minimum data rate of 4800 bits per second per 6.25 kHz of channel bandwidth. See 47 C.F.R. 90.203(j)(5); see also 47 C.F.R. 90.203(j)(3). Ritron did not request a waiver of the data efficiency standard, and the record does not support such a waiver. 33 See 47 C.F.R. 90.203(j)(3). 4 Federal Communications Commission DA 13-431 equipment operating with a channel bandwidth of 12.5 kHz also be capable of operating with a channel bandwidth of 6.25 kHz.34 13. It would be impractical to regulate equipment at the certification stage based on whether the equipment will be used by Industrial/Business or Public Safety licensees. Moreover, the narrowbanding rules have consistently been applied in the same manner to both groups of licensees.35 Consequently, this waiver applies to certification of all PLMR equipment in the 150-174 MHz and 450-

512 MHz bands regardless of end user-licensee. 14. Conclusion. We grant Ritrons request to the extent that we waive until January 1, 2015 the requirement that applications for equipment certification demonstrate 6.25 kHz voice capability. We deny Ritrons request for an indefinite waiver. We conclude that it would be contrary to the underlying purpose of the Commissions narrowbanding rules to delay the implementation of the 6.25 kHz voice capability requirement beyond the temporary waiver granted herein. 15. Accordingly, IT IS ORDERED pursuant to Sections 4(i), 11, 303(g), and 303(r) of the Communications Act of 1934, as amended, 47 U.S.C. 154(i), 161, 303(g), and 303(r), that the instant Petition filed by Ritron, Inc. on September 21, 2012, IS GRANTED IN PART and DENIED IN PART, to the extent set forth above. 16. This action is taken under delegated authority pursuant to Sections 0.31, 0.131, 0.191, 0.241, 0.331, and 0.392 of the Commissions Rules, 47 C.F.R. 0.31, 0.131, 0.191, 0.241, 0.331, 0.392.
