SCANNING
The TX3345 has a SCAN function that allows groups of user
programmable channels to be scanned for signals. Channels
can be scanned at 20 channels per second. When a signal
is found, scanning will pause on that channel to allow the
signal to be heard, then resume scanning when the channel
is clear again.
SCAN GROUPS
The TX3345 features two scan groups by default - Open
Scan and Group Scan.
Open Scan
Allows any of the installed channels to be scanned for
activity. If a busy channel is found, scanning will pause to
allow the signal to be heard. Once the channel has been
clear for 5 seconds, scanning will resume automatically.
e.g. Scanning channels 1-8 in Open Scan.
Group Scan
Also allows any of the installed channels to be scanned for
activity, but in addition, it inserts your Priority Channel into
the scan sequence. This means that your Priority Channel
will be monitored regularly while scanning to ensure that
no calls are missed. Any signals received on your Priority
Channel will take precedence over any signals received on
the other channels.
e.g. Scanning channels 1-8 with Priority Channel 20 in
Group Scan.
