PTT button
When you press and hold the push-to-talk (

call or to end the call, release the
PTT
button.
The
PTT
button can also be used to initiate an express call.

Emergency button
Depending on how your organisation has configured the physical
Emergency
button, the pressing of this red button initiates an emergency
group call to the selected group or a duplex individual call.
Volume buttons
The
Volume
buttons can be used for:
•
Controlling the volume level.
During a call, you can adjust the volume level of the incoming audio. If the
screen is on, the volume slider is shown; you can check the current volume
level there.
Note:
If there is no ongoing call or an active application with audio
focus, you can use the volume buttons to adjust the audio level of
incoming group calls and semi-duplex calls to a suitable level
beforehand. To adjust the audio level of duplex calls and 3GPP
calls, use the Android audio settings.
•
Changing the group when the PMR Status Bar is activated.
