OPERATION
SIMPLEX
(
NON-REPEATER
)
OPERATION
FM TRANSMISSION
•
Connect the microphone to the MIC jack, and press
the [FM/AM] key, as necessary, to select the “FM”
operating mode. Set the RF PWR control fully
clockwise.
‚
Close the microphone’s PTT switch to activate the
transmitter, and speak into the microphone in a
normal voice level. Release the PTT switch when
you wish to return to the receive mode.
ƒ
The microphone gain is set to a fixed value at the
factory. However, the Menu system includes pro-
vision for adjusting the microphone gain, if needed.
To adjust the microphone gain:
l Press the [MENU] button to activate the Menu
mode of operation.
l Rotate the SUB-TUNE knob to select Menu #25
(“
FM-PSET
”).
l Rotate the MEM/VFO CH knob to adjust the
mic gain. You may select from the default value
(“
32
”) or a value on an arbitrary scale of
0
~
63
. The “
O
FF
” selection transfers control of the
FM mic gain to the front panel’s MIC (GAIN)
control.
l Press the [MENU] key to exit the Menu mode.
l Close the microphone’s PTT switch, and speak
into the microphone to check the mic gain level.
If further adjustment is required, repeat the
above procedure.
Note: Because of international regulations, the per-
missible deviation on 29 MHz is about one-half
of that typically used on 50 MHz and higher.
Therefore, it is normal for 29 MHz FM signals
not to have as much audio “punch” as do FM
signals on, for example, 2 meters.
