Uniden BC785D Scanner User Manual


 
You can program conventional frequencies in the same bank as trunking systems.
After the scanner finishes checking a trunked system for activity, it will conventionally
scan the other frequencies in the bank (remember, only trunking frequencies are
programmed in Trunk mode).
To scan a mix of trunking and conventional banks, select the banks you wish to be active,
and then press SCAN. The scanner will instantly begin scanning. If you have not
programmed a trunking bank with talkgroup IDs, you will receive NO ID (----)
message for that bank. You can switch to Search mode and the scanner will search for any
active IDs on the system.
Note: To switch ID Scan or ID Search, press and hold TRUNK in the trunked system.
Multi-Track Operational Details
When more than one trunk system is active (for example two or more trunked systems or a
trunked system and one or more conventional frequencies), the radio jumps between
systems/frequencies as follows:
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, you will begin to hear
that communication and the scanner will of course display the proper talkgroup number
and any alpha tag. When the communication ends, the scanner will wait for the specific
periods 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 the specific periods. 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.
