IMPORTANT: To listen to the transmission, the mode setting of the trunking control or system channels
must match the mode setting of the associated ID list (MOT for Motorola and APCO-25, or ED for EDACS).
When an ID code is received, the ID list for the bank is searched, and if found, the text name stored for the
ID appears in the scanner’s display. If not found, scanning resumes immediately unless the bank is in open
trunking mode.
Setting Squelch for Trunking
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 find 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.
While the scanner is stopped on a voice channel (VC appears next to the frequency in the display), hold
down TRUNK (or press and release PAUSE) until ID hold ON appears in the scanner’s display.
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.
When ID hold is activated and the scanner receives a voice channel, the scan indication S at the first digit
in the top line changes to H to indicate that the call is being monitored while the scanner is in ID hold.
To release ID hold, press SCAN, PAUSE, or TRUNK.
Turning an ID Sub-Bank On or Off
Follow these steps to turn the ID sub-bank on or off during the program mode:
1. Press TRUNK repeatedly to select the desired sub-bank.
2. Press FUNC then 1 to toggle the sub-bank on or off. The on/off state of the sub-bank will appear in the
scanner’s display.
Follow these steps to turn the ID sub-bank on or off during the scan mode:
1. The channel storage bank must be set to Closed Mode to change the state of a sub-bank while
