USER'S MANUAL Acknowledging Special Precautions and the FCC Notice Cautions. Read this information before using your product. Modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. FCC compliance Information This device complies with part 15 of 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. Information to User This equipment has been tested and found to comply with the limits for a Class B digital device, Pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio Frequency energy and, if not installed and used in accordance with th einstruction, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, whic h can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
> Reorient or relocate the receiving antenna.
> Increase the separation between the equipment and receiver
> Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.

RADIO FREQUENCY ENERGY SAFETY INFORMATION This UNIMO transceiver has been tested and complies with the standards listed below, in regards to radio Frequency(RF) energy electromagnetic energy(EME) generated by the transceiver
> FCC RF exposure limits for Occupational use only. RF exposure limits adopted by the FCC are generally based on recommendations from the national council on radiation protection and measurement,
& the American National National Standards Institute.
> FCC OET Bulletin 65 Edition 97-01 Supplement C
> American National Standards Institute(C95.1-1992)
> American National Standards Institute(C95.3-1992) WARNING This UNIMO transceiver generates RF EME while transmitting. RF EME(Radio Frequency Electric &
Magnetic Energy)has the potential to cause slight thermal, or heating effects to any part of your body less than the recommended distance from this radio transmitter's antenna. RF energy exposure is determined primarily by the distance to and the power of the transmitting device. In general, RF exposure is minimized when the lowest possible power is used or transmission time is kept to the minimum required for consistent communications, and the greatest distance possible from the antenna to the body is maintain. The transceiver has been designed for and is classified for Occupational use only. Occupational/controlled exposure limits are applicable to situations in which persons are exposed to RF energy as a consequence of their employment, and such persons have been made aware of the potential for exposure and can exercise control over their exposure. This means you can use the transceiver only if you are aware of the hazards of operating a transceiver and are familiar in ways to minimize these hazards. This transceiver is not intended for use by the general public in uncontrolled environments. Uncontrolled environment exposure limits are applicable to situations in which the general public may be exposed to RF energy ,or in which the persons who are exposed as a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise control over their exposure The following list provides you with the information required to ensure that you are aware of RF exposure and of how to operate this transceiver so that the FCC RF exposure limitations are not exceeded.
> While transmitting(holding the PTT switch), always keep the antenna at least 2.5cm (1 inches) from your body or face ,as well as from any bystanders
> 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
> Use only the specified antenna for this transceiver; this may be either the antenna provided with the transceiver or another antenna authorized by UNIMO. Use only UNIMO authorized accessories (antennas, battery packs, belt clips, Speaker/Mics or headsets etc.):
When worn on the body, always place the radio in a UNIMO recommended clip or carrying case meant for this product. The use of other than recommended or approved body-worn accessories may result in RF exposure levels which exceed the FCC's occupational /controlled environment RF exposure limits.

CAUTION To ensure that your exposure to RF EME is within the FCC limits for occupational use, you must observe and adhere to the above points. Electromagnetic Interference Compatibility Electronic devices are susceptible to electromagnetic interference(EMI)if they are not adequately shielded or designed for electromagnetic compatibility. Because this transceiver generates RF energy, it can cause interference to such equipment.
>Turn OFF your transceiver where signs are posted to do so. Hospitals and health care facilities use equipment that is sensitive to electromagnetic radiation.
> Turn OFF your transceiver while on board an aircraft when so instructed, Use of the transceiver must be in accordance with airline regulations and/or crew instructions.

1.2 LCD DISPLAY 2. HOW TO USE 2.1 POWER ON/OFF, VOLUME CONTROL Turing the power switch clockwise turn power ON and sets the volume level. When the power is on, transceiver's ID and name appear on the LCD 2.2 PUSH-TO-TALK(PTT) SWITCH When depressed and held, engages the transmitter and puts radio in the transmit mode. at that time, TX lamp(red) is lighted. When released, The radio operates in the receive mode. 2.3 MONITOR BUTTON Selects the mode of operation, Carrier squelch or tone squelch. in CASE 1 : In case of pressing the monitor key for less then 2Sec, checks the channel use scanning each channel. Then monitor operation stops as monitor key is released, The receive mode begins. CASE 2 : In case of pressing the monitor key for 2Sec, keeps the receive mode until When the monitor key is pressed, The current operation stop and returns to the receive mode. identifying the next monitor key. stop to the channel in use and 2.4 CHANGE THE CHANNEL Use the channel button for changing the channel. If press the UP[ ] button, channel number increases. If press the DOWN[ ] button, the channel number decreases. If press and hold the button for a while, the channel is rapidly changed. 2.5 CHANGE THE TX OUTPUT The TX output is selected between HIGH(4W) and LOW(1W). If press the UP button with PTT button pressed, it is converted to "H"(High). If press the DOWN button with PTT button pressed, it is converted "L"(Low).

2.6 TRANSMISSION In Tx mode, as soon as pressing the PTT button, DTMF and 5-Tone ID are transmitted. At that time, you can't communicate and the Rx/Tx lamp is lighted. Note) If it is keyed continuously for longer than the programmed time, the transmission is inhibited. (BCLO, TOT feature) Fig.4 Transmission 2.7 RECEIVING You can receive with PTT button released. DTMF or 5-tone sounds and display the caller's name on LCD according to Transceiver.(See Call Mode section) Whether it is in bad condition or has a different tone(CTCSS/DCS) in spite of same frequency, it can't be received. In normal, it can receive all signals by pressing the monitor button and it continues the monitor mode by pressing the button for 2 seconds. Press the monitor button again to release the monitor mode. Select the channel for the call.
