Volume control

Control of the volume level of the Bose Aviation Headset X requires

adjustments at both the aircraft intercom or radio and at the headset

installed control module.

Note:

Avoid setting the volume levels too high. Exposure to loud

sounds may cause hearing damage. The headset volume control

cannot completely turn off the volume.

• Turn on the power switch located on the control module.

• Set the aircraft communication system to a safe

operating level.

• Set the volume levels for the left and right earcups

by rotating the thumb wheels as needed.

Note:

The microphone and cable assembly can be attached to either

earcup. Thumb wheel #1 will always control the volume level of the

earcup with the microphone and cable assembly attached. Thumb

wheel #2 will always control the volume level of the earcup without the

microphone and cable assembly attached.

Note:

If you are connecting the headset to your aircraft for the first

time, turn down the master output level of your radio/intercom system

to avoid exposure to high volume levels.
