trunking operation
setting squelch for trunk scanning
For optimal receiver performance when scanning both
trunked and conventional systems, we recommend that
you set the squelch close to threshold. Navigate to a
programmed channel in manual mode. While the channel
is idle, turn the squelch control fully counterclockwise. You
will hear a loud rushing noise from the speaker. Turn the
squelch control clockwise until the noise stops. You may fi nd
it necessary to set the control a bit further in the clockwise
direction to prevent very weak signals or interference from
stopping the scan operation.
talkgroup ID hold
You can set your scanner to follow a trunking signal that you
want to track during scanning.
1. While the scanner is stopped on a voice channel (VC
appears), hold down TRUNK (or press and release PAUSE)
until ID hold ON appears on the display.
2. To manually activate ID hold mode on a selected ID, enter
the ID list, scroll to the desired ID, then press FUNC TRUNK.
The scanner will initiate ID hold operation on the selected
talkgroup.
3. When ID hold is activated and the scanner receives a
voice channel, the scan indication S at the fi rst digit in
the top line changes to H to indicate that the call is being
monitored while the scanner is in ID hold.
4. To release ID hold, press SCAN, PAUSE, or TRUNK.
