Volume control

The left and right volume control wheels on the control module adjust the volume of the corresponding earcup. With Acoustic Noise Cancelling® off, volume control will be set to the maximum level.

CAUTION: Avoid setting the volume levels too high. Exposure to loud sounds may cause hearing damage.

Holding the control module upright and facing you:

Use the left wheel to adjust volume of the left earcup.

Use the right wheel to adjust volume of the right earcup.

Overall headset volume control requires adjustments at both the aircraft intercom or radio and at the headset control module. Even at its lowest setting, neither volume control wheel can completely turn off the volume.
