WHAT TO DO
Make sure the Intercom operation switch is correctly set for your
intercom system. See "Operation Switches" on page 23.
Make sure the terminator cover is securely installed. See "Move the
microphone" on page 26.
Depending on how your audio jacks are wired, there may be
only one channel of audio supplied to the headphone jack. If the
Intercom (MON-ST) operation switch is set to ST and you only hear
communications on one side, set the operation switch to MON to
play audio on both sides. 5-pin XLR models are mono audio only.
