Using the Headset
• Double-click the power button to dim the power and Bluetooth wireless technol-
ogy 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
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 vol-
ume 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:

WARNING: Replace batteries with alkaline batteries only. Do not use any other battery
