w
Set the squelch level.
➥
Rotate the main band’s [SQL] fully counterclockwise in
advance, then rotate the [SQL] clockwise until the noise
just disappears.
• When interference is received, rotate the [SQL] clockwise
again for attenuator operation. (p. 17)
e
Set the operating frequency in the main band. (pgs. 11–13)
r
When receiving a signal on the set frequency, squelch
opens and the transceiver emits audio.
• “BUSY” appears and the S/RF
indicator shows the relative
signal strength for the re-
ceived signal.
✔
CONVENIENT!
The main band’s audio and squelch level can also
be adjusted with [
VOL
Y
(TONE-1)]/[
VOL
Z

This function is used to listen to weak signals without disturb-
ing the squelch setting.
➥
Push [DUP•MONI] for 1 sec. to open the squelch.
• Push [MIN•BAND] to select the desired band (left or right) as the
main band in advance.
• “BUSY” blinks.
• Push [DUP•MONI] for 1 sec. again to cancel the function.
