4 BASIC OPERATION N Transmitting CAUTION: Transmitting without an antenna will damage the transceiver. NOTE: To prevent interference, push and hold [SQL] to listen on the channel before transmitting. q Set the operating frequency. (p. 23) • Transmission is available on the 144 MHz/440 MHz amateur bands only. • Select output power if desired. See next page for details. w Push and hold [PTT] to transmit. • Tx/Rx indicator lights red. • S/RF meter shows the output power level. e Speak into the microphone using your normal voice level. • DO NOT hold the transceiver too close to your mouth or speak too loudly. This may distort your speech. r Release [PTT] to return to receive. Tx/Rx indicator Microphone WARNING! NEVER continuously transmit for long periods of time. When the transceiver is used for continuous prolonged transmission at high power, the transceiver radiates heat to protect itself from overheating and transceiver's chassis will become hot. This may cause a burn. DO NOT operate the transceiver in a situation that will obstruct heat dissipation, especially if the transceiver is operated with an external power supply. Heat dissipation may be affected, and it may cause a burn, warp the casing or damage the transceiver. NOTE: Transmit power set 2.5 W (MID) automatically when the transceiver radiates heat. CONNECT the rated range voltage when using external power supply. 26

When the transceiver is used for continuous prolonged
transmission at high power, the transceiver radiates heat
to protect itself from overheating and transceiver’s chassis
will become hot. This may cause a burn.
DO NOT

obstruct heat dissipation, especially if the transceiver is
operated with an external power supply. Heat dissipation
may be affected, and it may cause a burn, warp the casing
or damage the transceiver.
