ECEPTION
Rotate the
VOL
knob for a comfortable listening level on the incoming signals or
noise present on the speaker.
When no signal is present on the channel, press the [
SQL
] button (the [
P
ROGRAM

MABLE
] button which assigns the “Squelch” func-
tion: the factory default is [
P2

vate the “Squelch Adjusting” mode, then press
the [
]/[ ] button to the point where the background noise is just silenced; finally
press the [ P2

Unless you are responsible for listening for very weak signals (very near the back-
ground noise), silencing the receiver using the circuitry is usually preferable in most
applications.
When a signal strong enough to override the squelch threshold is received, the incom-
ing signal will be heard in the speaker, and the
TX/BUSY indicator glows green.
When the incoming signal is disappeared, the green TX/BUSY indicator will disap-
peared.
When a signal is being received, the S/PO meter will become illuminated according
to the incoming signal strength. You may use this S/PO meter reading to compare
communications path effectiveness on different
channels, or to assist with optimum antenna ro-
tation, if a directional antenna is being used.
When receiving an impulse noise, such as that from a power line or a vehicle, press
the [
NB
] button (the [
P

function: the factory default is [ S2
] button) to reduce the noise level. When the noise
blanker is activated, the “ ” icon will be illu-
minated. Press the [ NB
] button again to disable
the noise blanker.
If the station you are listening to should drift or otherwise be unclear (the voice may
sound too high-pitched or too low-pitched), press the [
