scanning a talk group ID list
Press SCAN/MANUAL to begin scanning the lists you have stored.
If an ID is incorrect, Error ashes twice and the scanner beeps
several times, then the scan list numbers appear at the top of the
display. To correct the entry, delete the incorrect ID.
One of the ten scan lists must always be active. You
cannot remove all of them.
To remove a scan list from active scanning, use the number keys to
enter the scan list’s number. The scan list number turns off, and the
IDs in that list are not scanned.
To restore a scan list to active scanning, use the number keys to
enter the number of the list again.
locking out a talk group ID
Many municipal and commercial services use trunk systems to
transmit signals from devices such as water-meter transmitters,
door alarms, and traf c signals. These are not voice signals, but are
assigned talk group IDs. To scan more ef ciently, you can lock out
up to 100 talk group IDs.
To lock out an ID, press L/O when the ID appears. The ID is locked
out, and the next active ID appears. If you lock out an ID while
searching, it is also locked out of the scan list(s).
To unlock a single ID, complete the following steps:
1. Select the trunking programming mode and the bank you want
to review.
