down the radio automatically.
Just press and hold in the

You can reduce the microphone input level when operating on tightly-clustered frequencies
(channel spacing of 12.5 or 15 kHz). This will reduce the transmitter deviation, thus mini-
mizing interference to other users.
To configure for the narrower bandwidth, use the following procedure:
1. Press and hold in the [
BAND
(
SET
)] key for 1/2 second to enter the Set mode.
2. Rotate the
DIAL
knob to select Menu #47 (
WID.NAR
).
3. Press the [
BAND
(
SET
)] key momentarily, then rotate
the
DIAL
knob to change the display to “
NARROW
.”
4. Press the [
BAND
(
SET
)] key momentarily to save the
new setting, then press and hold in the [
BAND
(
SET
)]
key for 1/2 second to exit to normal operation.
To restore the normal (higher) microphone input level, select “
WIDE
” in step 3 above.
