BASIC OPERATION

N Transmitting

(BAND) to listen on the frequency before transmitting.

Microphone

[PTT]

q  Set the operating frequency. (p. 20)

• Transmission is available on the 

144 MHz/400 MHz amateur bands only.

• Select output power if desired. See pre-

vious page for details.

w  Push and hold [PTT] to transmit.

• “

” appears.

• 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.

rRelease [PTT] to return to receive.

R 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 ob-
struct heat dissipation, especially if the transceiver is oper-
ated with an external power supply. Heat dissipation may 
be affected, and it may cause a burn, warp the casing or 
damage the transceiver.

NOTE: When the transceiver becomes hot from continuous 
transmission, etc., the transceiver’s heat protection gradu-
ally reduces the output power to 2.5 W (Mid), then it stops 
transmission after that, to protect the transceiver itself until 
it has cooled down.

• “M” (Power icon) blinks during the heat protection reduces the 

output power.

• “Hot” is displayed during the heat protection inhibits the transmis-

sion.

CAUTION: Transmitting without an antenna will damage the 

transceiver.
