Using the Headset
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
power indicator changes color to indicate the power status, as follows:

Warning: Replace batteries with alkaline batteries only. Do not use any other
battery chemistries.
*When the batteries reach this level, the Bluetooth feature is disabled to conserve
remaining power. You will hear a tone, indicating that your Bluetooth device is
being disconnected and the Bluetooth feature is turning off.
Intercom volume controls
The left and right volume control wheels on the control module adjust the intercom
volume of the corresponding earcup. With Acoustic Noise Cancelling
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.
