Motorola XPR 5550 Desktop Microphone Button Left and Right
My question is: The RMN5050 microphone I'm using for the radio has two buttons on it. The right-side "lightning bolt" button is the PTT button to transmit, but I can't figure out what the left-side "speaker icon" button does. When I try to push it, nothing appears to happen.
Does anybody know what the purpose of the left-side "speaker icon" button is?
