8.22 TALK GROUP LOCK OUT
There are two ways to focus voice communications by suppressing calls from talk groups in the active
profile.
•
No Scan
. By changing the Scanning Mode to “No Scan” only the selected talk group is scanned.
•
Lock Out.
By locking out selected talk groups, background noise or chatter can be eliminated and
scanning resources can be focused on just those groups whose calls you wish to monitor.
Lock out is a listening (receive) function and only blocks received calls on locked out talk
groups. Lock out does not affect transmit capability. “No Scan” and “Lock Out” do not
apply to recent emergency lock outs.
Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice
calls can be heard on the radio. Talk group lock out is a scan-related feature. With lock out, one or more
talk groups in the active profile can be temporarily disabled from being scanned. Calls are not received on
locked-out talk groups. Lock out settings are not retained between profile changes or when the radio is
power cycled.
