Intercom Audio Gain Jump
- The Intercom Audio Gain Jump switch is an incremental
gain increase of the intercom sound level. Each headset is also equipped with an in-
dependent volume control. If an overall higher intercom sound level is desired, the
Intercom Audio Gain Jump switch may be used. The gain is increased when the
switch is in the “up” position and decreased in the “down” position.

- The Transmit Audio Adjust is a rotational adjustment of the audio broadcast
