Functions and Settings
When scanning remains on a non-priority channel, the
radio continues to monitor activities on the priority channel,
and jumps to the priority channel if activity is detected.

nel by preventing transmission if another talk group is
already on the air. The radio will generate a continuous
tone upon PTT press if a transmission is not allowed.
Release the PTT to cancel the tone.
