RANSMISSION
To transmit, simply close the
PTT
( P ush T o T alk) switch on the microphone when the
frequency is clear. Hold the microphone approximately 25 mm (1”) from your mouth, and
speak into the microphone in a normal voice level. When your transmission is complete,
release the
PTT
switch; the transceiver will revert to the receive mode.
During transmission, the “main” band
BUSY/TX
indicator changes from Green to Red, and
the S&PO meter segments rise up according to the power output selected.
Power Output Setting
Four power output levels are available on this transceiver: 5 watts (LOW), 10 watts (MID 2),
20 watts (MID 1) and 50 watts (VHF) or 35 watts (UHF) on HIGH.
To change the power level, press the [ LOW
] key. Each time you press the [
LOW
] key, the
new power level will be displayed for a few seconds, then the regular display mode will
reappear.
The power level can be set independently for each band. Also, the power level may be stored
in a memory register, if desired.
