When conventional channels are programmed, the squelch level can
be set the AUX1 or AUX2 switch programmed to select the squelch
adjust function. If this switch is not programmed, the squelch level is
fixed at a default setting. Proceed as follows:
1. Select a conventional channel that is not busy. Take the microphone
off-hook to enable monitoring.
2. Press the AUX1 or AUX2 switch (whichever is programmed for
squelch adjust) and the appropriate decimal point lights to indicate that
the squelch adjust mode is enabled.
3. Within 8 seconds, press the CHL down switch until noise is heard and
then press the CHL up switch until the noise just mutes.
4. To select the current level and exit this mode, press the AUX1/AUX2
switch again. This also occurs automatically 2 seconds after a change
is made or 8 seconds after no activity.
5. If both narrow band and wideband channels are programmed, perform
this adjustment with each channel type selected because separate
settings are maintained for each.
NOTE: If weak messages are not heard or if unsquelching occurs when
no messages are present, slight readjustment may be required.
