The handset will transmit only to phones set to receive on the selected channel. The
Priority Channel transmits to all channels.
Subscribed Channels
Displays all enabled PTT channels. The handset will receive PTT transmissions on all

PTT Vibrate
To enhance the alerting of a PTT call, PTT Vibrate may be enabled. When PTT Vibrate is
enabled, the handset will vibrate three times whenever a PTT broadcast is received,
whether the handset is in standby or in a call. If in a call, the chirp alert will also sound.
The vibration does not replace any PTT tone volume already set.
To set the handset for PTT vibrate only, enable PTT Vibrate and set the tone volume to
zero.
