• Double-click the power button to dim the power and Bluetooth
technology indicators. To toggle the indicators between dim and bright,
rapidly press the power button twice.

Volume control

The left and right volume control wheels on the control module adjust the
volume of the corresponding earcup. With Acoustic Noise Cancelling
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.

Power indicator

New alkaline AA batteries will generally supply at least 45 hours of power for
the headset. Battery life varies with the ambient noise level of the aircraft,
temperature, ear cushion condition, use of the Bluetooth feature, and age of
the batteries. The power indicator changes color to indicate the power status,
as follows:
