  • Page 3 V4000 SERIES OPERATION: Turn the radio on and operate it as explained in the operating instructions supplied with the radio. Installing the headset bypasses the radio’s speaker and routes the output to the headset’s speaker. The in-line push-to-talk (PTT) switch disables the radio’s microphone and enables the boom microphone.
