Trunk Scanning
Trunk Scanning
In each bank, you can mix conventional channels and frequencies
in a bank. However, you can scan only one trunking mode at a time,
either EDACS, Motorola, or LTR.
Press SCAN. The scanner scans through unlocked channels in
active banks. To focus on trunk scanning, you can turn off banks
that contain only conventional channels. To change the scanning
direction, press S or T.
For Motorola channels, your scanner displays the Talk Group ID
memory location, received frequency, voice channel (VC), and the
Motorola ID number.
Notes:
• Your scanner automatically mutes the audio while it decodes
control channel data. However, we recommend you turn SQ
clockwise and leave it set to a point just after the hiss stops.
This lets the scanner quickly acquire the data channel.
• For Motorola trunking systems, more than one talk group
can transmit at a time. If you manually tune the scanner, you
will hear the talk group on that channel, but the display will
alternate between all active Talk Group IDs.
• For EDACS and Motorola (above 406 MHz range), the scanner
monitors the control channel between each transmission to
identify talk groups. For some Motorola (under 512 MHz range)
and LTR systems, the scanner uses the subaudible data sent
with each transmission to identify talk groups.
Trunking Delay
You can set a Talk Group ID delay separately from the channel
delay. When active, the scanner checks the Talk Group ID for the
delay time when a transmission ends.
To set a Talk Group ID delay:
1. Press FUNC then •/DELAY while you are programming the
Trunk Group ID.
“ENTER key saves. 2.0 seconds”
appears.
2. Use S or T to set ID Delay: None, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5,
or 4.0 seconds.
3. Press ENT.
Locking Out Talk Group IDs
You can only lock out Talk Group IDs when the scanner is in the
Closed mode.
To lock out Talk Group IDs:
1. Press PROG then TRUNK.
2. Press FUNC, S or T to move to the desired bank.
3. Press S or T to select the ID.
4. Press L/OUT to lock out the ID.
“lo”
changes to
“LO.”
5. To remove the lockout from a trunking ID, manually select the
ID memory, and press L/OUT.
“LO”
changes to
“lo.”
Note: You cannot clear all lockouts from a talk group at the
same time.
To review locked-out Talk Group IDs:
1. Press PROG then TRUNK.
2. Press FUNC then L/OUT. The first locked out ID appears. If the
ID memory bank has no locked-out ID, you hear the low beep
tone.
3. Press S or T to scroll through the list.
4. Press PROG to exit.
