Turning the Speaker On/Off
On the Call screen, there is a toggle that indicates whether the speaker is ON or OFF for PTT calls.
When the speaker is OFF, you hear the PTT call audio in the phone’s earpiece, and when it is ON
the audio is heard through the speaker.

volume up and down keys. When the volume is adjusted during a PTT call, that setting is retained
for subsequent calls, including cellular calls.
