TRANSMITTING
1 To 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.
2 When 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
M4 market version only: The output power of M4 market models
cannot be adjusted. It is fixed at 25 W.
You can configure different power levels for transmission.
1 Press [F], [MENU] and turn the Tuning control to
select Menu No. 6 (TXP).
2 Press [MENU] and turn the Tuning control to select
“H” (high; default) or “L” (low) power.
3 Press [MENU] to store the setting or any other key to
cancel.
4 Press any key other than [MENU] to exit Menu Mode.
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
This is the basic mode for changing the operating
frequency. To enter VFO Mode, press [VFO].
Turn the Tuning control clockwise to increase the
frequency and counterclockwise to decrease the
frequency, or use Mic [UP]/[DWN].
Press and hold Mic [UP]/[DWN] to step the frequency
repeatedly.
