You can reduce the receiver bandwidth and microphone deviation level when operating on
tightly-clustered frequencies (channel spacing of 12.5 or 15 kHz). This will reduce the
transmitter deviation, thus minimizing interference to other users.
To configure for the narrower bandwidth, use the following procedure:
1. Press and hold in the [ MHz ( SET )] key for one second, then
rotate the DIAL knob to select "59 W
2. Press the [ MHz ( SET )] key, then rotate the DIAL knob to
change the display to "NARROW
kHz Bandwidth)".
3. Press and hold in the [ MHz ( SET )] key for one second to save the new setting and exit
to normal operation.
4. To return to wide bandwidth and deviation, repeat the above procedure, selecting "WIDE
(±5 kHz Deviation, 15 kHz Bandwidth)" in step 2 above.
At the factory, a microphone gain has been programmed that should be satisfactory for the
supplied MH-48

you may wish to set a different Mic Gain level, using Set Mode item "27 MCGAIN
1. Press and hold in the [ MHz ( SET )] key for one second, then

set the desired level (Default: LVL 5
3. Press and hold in the [ MHz ( SET )] key for one second to
