TRANSMITTING
1To transmit, hold the microphone approximately 5 cm
(2 inches) from your mouth, then press and hold Mic
[PTT] and speak into the microphone in your normal
tone of voice.
•“ ” and the RF Power meter appears. The RF
Power meter shows the relative transmit output power
().
•If you press Mic [PTT] while you are outside the
transmission coverage, a high pitched error beep
sounds.
2When you finish speaking, release Mic [PTT].
Note: If you continuously transmit for longer than the time specified in
Menu No. 21 (default is 10 minutes) {page 62}, the internal time-out
timer generates a warning beep and the transceiver stops
transmitting. In this case, release Mic [PTT] and let the transceiver
cool down for a while, then press Mic [PTT] again to resume
transmission.
SELECTING AN OUTPUT POWER

◆Do not transmit at high output power for an extended period of
time. The transceiver could overheat and malfunction.
◆Continuous transmission causes the heat sink to overheat. Never
touch the heat sink when it may be hot.
Note: When the transceiver overheats because of ambient high
temperature or continuous transmission, the protective circuit may
function to lower transmit output power.
SELECTING A FREQUENCY
VFO MODE
