Scanning Programmed Channels
Before you start to scan, you must first program channels. See “Programming” on Page 35
and “Programming Conventional Channels” on Page 39 (for conventional channels) or
“Programming Trunked Systems” on Page 41 (for trunking systems) for complete
instructions.
To begin scanning, simply turn on the scanner or, if the scanner is not currently scanning,
press
SCAN
.
The scanner checks each system you have programmed that is not locked out and stops if
there is activity.
SCAN
scrolls across the display, right to left.
When the scanner receives a signal on a programmed channel, it stops on that channel
and displays the channel information.
The bank indicators A – J selected for scanning appear, and the bank you are currently
monitoring flashes. You can deselect banks from active scanning by pressing that bank’s
key (
A
-
J
). The indicator for each deselected bank turns off, and the scanner does not scan
that bank’s channels.
Note
: One bank must always be active. You cannot deselect all ten banks at the same
time. If you try to turn off all the banks, the scanner automatically selects the first bank.
To restore a bank to active scanning, press the bank’s letter. The bank’s indicator appears.
