LOCKINg/UNLOCKINg CHANNELS
You can lock channel so that they are not scanned, even if their bank is
turned on. Simply press L/O when the scanner stops on a transmission on
the frequency or manually select the channel, then press L/O. The
L / O
icon
displays when it is set to a locked out channel.
To unlock a channel, manually select the channel then press
L/O. The scanner
turns off the
L / O
icon and includes the channel when scanning its bank.
To unlock all channels related to a specific bank in Scan mode, press
and hold L/O for 2 seconds. The scanner beeps twice and the
L / O
icon
disappears.
USINg PRIORITY SCAN
You can set one channel in each bank as a priority channel. If you turn on the
Priority feature, the scanner will check the priority channel in enabled banks
every 2 seconds, even if it has stopped on a transmission on another channel.
To set the channel in a bank to be the priority channel, manually select the
channel; then, while holding on the memory, press E/PgM to put the scanner
in Program mode and press PRI. The scanner turns on the P icon when it is
stopped on a channel designated as priority.
To switch between Priority Scan/Priority DND/Off, press
PRI while the
scanner is scanning or holding on a channel (but not in Program mode). You
will notice a short break in audio every 2 seconds as the scanner checks
the enabled priority channel. If there is a transmission on a priority channel,
the scanner will immediately tune to that channel. If Prirority DND is set, the
scanner does not check Priority channels during receiving.
SETTINg CHANNEL DELAY
You can set the scanner to pause for 2 seconds at the end of a transmission
on a channel. This is useful to help prevent missed replies. Delay is turned on
by default when you program a channel. To turn Delay off (or back on), select
the channel and then press DELAY. The scanner turns on the
D E L A Y
icon
for channel that have been programmed with Delay.
SEARCHINg FOR ACTIVE FREQUENCIES
Many people enjoy searching for the unknown frequencies that are in use in
their area but are not posted to any site or in any publication. The BC345CRS
has two ways to search:
x Limit Searcing. Searches between two designated frequencies, creating
upper and lower limits.
x Service Searching. Searches for specific types of agencies based on the
FCC’s standard frequency allocation for such services.
