Uniden APCO 25 Scanner User Manual


 
TRUNK SCAN: The scanner moves to a trunked system and looks for IDs in your Scan
List(s) for up to 1 second. If it finds no activity on your programmed talkgroups, it moves
on to conventional channels in the same bank or to the next active bank.
If the scanner finds that a talkgroup in one of your active Scan Lists becomes active, you
will begin to hear that communication and the scanner will display the proper talkgroup
number and any alpha tag. When the communication ends, the scanner will wait for 2
seconds for any further replies and, if none, the scanner will move to the conventional
channels in the same bank or to the next bank. The scanner will not look for any other
IDs within the same trunked system (as this would slow the scan process). If you press
RSM while you are listening to one ID, the scanner will check to see if another ID in your
Scan List is active. It will disregard the ID to which you were just monitoring.
TRUNK SEARCH: This mode works similarly to Trunk Scan. If the scanner finds any (non-
locked-out) ID when it checks the control channel, you will hear it. You will then hear any
replies that follow within 2 seconds. After that the scanner will move on and not
continuously search the system for additional IDs (on busy systems you would never leave
the system if this were the case). If you press the
RSM key while monitoring one ID, the
radio will check if any other IDs are active (it will disregard the ID you just left), and if none
are active, it will move on.
