TX3345 INSTRUCTION MANUAL PAGE 11
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.
