Lock Out. By locking out selected talk groups, the “chatter” of the locked-out talk groups cannot be heard. This
focuses the user’s scanning resources to calls only on desired talk groups.
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 gr
not retained between profile changes or when the radio is power cycled.
Lock out is a listening (receive) function and only blocks received calls on locked out
talk groups. Lock out does not affect transmit capability. The above methods 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.
If the Scan Mode is “Fixed,” P1 and P2 groups CANNOT be locked out. See Section
6.25 for more information.
The default emergency and emergency-capable talk groups can be locked out if they are NOT in an
emergency state. If a talk group is locked out and is subsequently changed to the currently selected talk
group, it will automatically be unlocked by the radio so the user can hear calls on the talk group. The
radio may be configured so all talk groups are automatically locked out by default. In this case, they must
be manually unlocked, if desired.
