RECEIVE AND TRANSMIT
n Functions for transmit
D Output power
The transmit output power can be continuously adjust-
ed with [RF PWR].
Available power
144 MHz band
430(440) MHz band : 5–75 W
1200 MHz band
n Transmission via
microphone
When transmitting with a microphone, push [PTT] and
speak into the microphone at a normal voice level.
To maximize the readability of your transmitted sig-
nal (voice), pause a few sec. after pushing [PTT]. Do
not hold the microphone too close to your mouth.
D Microphone gain
Rotate [MIC GAIN] clockwise to increase, counter-
clockwise to decrease the microphone gain.
9–12 o'clock position is recommended for [MIC
GAIN].
n Indications during transmit
D Transmit indicator
The MAIN band indicator lights red while transmitting.
However, the SUB band indicator lights red during sat-
ellite operation.
D RF power indicator
The S-meter for the MAIN band is used as the RF
power indicator to indicate the relative output power
level. However, the S-meter for the SUB band is used
as the RF power indicator during satellite operation.
D Time-out timer
The time-out timer limits the continuously transmitta-
ble time period, and is selectable from 3, 5, 10, 20, 30
min. and OFF in TRANSMIT set mode. (p. 66)
D PTT lock function
Deactivate [PTT] and [TRANSMIT] switches. The func-
