SCANNING
OVERVIEW
The TX4600 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 TX4600 features two scan groups - 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.
eg: 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 also 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.
