Scanning - GME GA9800 Instruction Manual

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.

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 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.
