Use PTT Vibrate
To enhance the alerting of a PTT call, PTT Vibrate may be enabled on the Config menu.
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.
PTT Vibrate is disabled by default.
