IC-M90.qxd 04.8.23 3:53 PM Page i SAFETY TRAINING INFORMATION Your Icom radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as Occupational Use Only, meaning it must be used only dur-

ing the course of employment by individuals aware of the haz-

ards, and the ways to minimize such hazards. This radio is NOT intended for use by the General Population in an un-

controlled environment. W ARNING This radio has been evaluated for compliance at the distance of 2.5 cm with the FCC RF exposure limits for Occupational Use Only. In addition, your Icom radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for ex-

posure to humans:

FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electro-

magnetic Fields. American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Elec-

tromagnetic Fields, 3 kHz to 300 GHz. American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields RF and Microwave. The following accessories are authorized for use with this product. Use of accessories other than those specied may result in RF exposure levels exceeding the FCC requirements for wireless RF exposure.; Belt Clip (MB-

86/103), Rechargeable Ni-Cd Battery Pack (BP-225) and Alkaline Battery Case (BP-223). To ensure that your expose to RF electromagnetic en-

ergy is within the FCC allowable limits for occupational use, always adhere to the following guidelines:

DO NOT operate the radio without a proper antenna attached, as this may damaged the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the man-

ufacturer or antenna specically authorized by the manufacturer for use with this radio. DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting more than 50% of the time can cause FCC RF expo-

sure compliance requirements to be exceeded. The radio is transmitting when the TX indicator lights red. You can cause the radio to transmit by pressing the PTT switch. ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and only use the Icom belt-clips which are listed on page 33 when attaching the radio to your belt, etc., to ensure FCC RF ex-

posure compliance requirements are not exceeded. To provide the recipi-

ents of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and slightly off to one side. The information listed above provides the user with the information needed to make him or her aware of RF exposure, and what to do to assure that this radio operates with the FCC RF exposure limits of this radio. Electromagnetic Interference/Compatibility During transmissions, your Icom radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites. Occupational/Controlled Use The radio transmitter is used in situations in which persons are exposed as consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure.

NEVER hold the transceiver so that the antenna is closer than 2.5 cm (1 inch) from exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm

(2 to 4 inches) away from the lips and the transceiver is verti-

cal. NEVER connect the transceiver to a power source other than the BP-225 or BP-223. Such a connection will ruin the transceiver. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below 20C (4F) or above

+60C (+140F): MARINE, 30C (22F) or above +60C

(+140F): LMR. KEEP the transceiver out of the reach of children. KEEP the transceiver at least 0.9 meters (3.0 ft) away from your vessels magnetic navigation compass. MAKE SURE the exible antenna and battery pack are securely attached to the transceiver, and that the antenna and battery pack are dry before attachment. Exposing the inside of the transceiver to water will result in serious damage to the transceiver. BE CAREFUL! The IC-M90 employs waterproof con-

struction, which corresponds to JIS waterproof specication, Grade 7 (1 m; 3 ft depth for 30 min.). However, once the transceiver has been dropped, waterproong cannot be guar-

anteed due to the fact that the transceiver may be cracked, or the waterproof seal damaged, etc. For U.S.A. only CAUTION: Changes or modications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations.

priorities and keep an up-to-date copy handy. Safety and distress calls take priority over all others.

(2) OPERATORS LICENSE A restricted Radiotelephone Operator Permit is the license most often held by small vessel radio operators when a radio is not required for safety purposes. 1 You must monitor Channel 16 when you are not operating on another channel. False or fraudulent distress calls are prohibited under law. D Privacy Information overheard but not intended for you cannot law-

fully be used in any way. Indecent or profane language is prohibited. D Radio licenses

(1) SHIP STATION LICENSE When your craft is equipped with a VHF FM transceiver, you must have a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed. Inquire through your dealer or the appropriate government agency for a Ship-Radiotelephone license. This license in-

cludes the call sign which is your crafts identication for radio purposes. The Restricted Radiotelephone Operator Permit must be posted near the transceiver or be kept with the operator. Only a licensed radio operator may operate a transceiver. However, non-licensed individuals may talk over a transceiver if a licensed operator starts, supervises, ends the call and makes the necessary log entries. A current copy of the applicable government rules and regu-

lations is only required to be on hand for vessels in which a radio telephone is compulsory. However, even if you are not required to have these on hand it is your responsibility to be thoroughly acquainted with all pertinent rules and regulations. NOTE: Even though the IC-M90 is capable of operation on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83, according to FCC regulations these simplex channels can-

not be lawfully used by the general occupational in USA waters. 1 IC-M90.qxd 04.8.23 3:53 PM Page 2 2 SUPPLIED ACCESSORIES AND ATTACHMENTS I Supplied accessories The following accessories are supplied:
