Functions for transmit
Output power
The transmit output power can be continuously ad-
justed with [RF PWR].
Available power
144 MHz band : 5100 W
430(440) MHz band : 575 W
1200 MHz band : 110 W (optional)
NOTE: To prevent interference, listen on the fre-
quency to make sure the frequency is clear before
transmitting by pushing [CHECK 7].
[RF PWR]
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.
Microphone gain
Rotate [MIC GAIN] clockwise to increase, counter-
clockwise to decrease the microphone gain.
912 oclock position is recommended for [MIC GAIN].
[PTT] switch
HM-12
Indications during transmit
Transmit indicator
The MAIN band indicator lights red while transmitting.
However, the SUB band indicator lights red during
satellite operation.
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.
Time-out timer
The time-out timer limits the continuously transmittable
time period, and is selectable from 3, 5, 10, 20, 30 min.
and OFF in TRANSMIT set mode. (p. 66)
PTT lock function
Deactivate [PTT] and [TRANSMIT] switches. The func-
tion can be switched ON and OFF in TRANSMIT set
