Setting the control module operation switches

The headset is shipped with factory-set operation defaults. If you want to alter these defaults, you can change the operation switches located inside the control module battery compartment:

Open the battery compartment by pressing firmly on the finger indent and sliding the cover down. The cover is tethered to the module. Do not attempt to detach it

If batteries are installed, remove them. In the battery compartment, you can see and change the switch positions

To change a switch position, use a pen or a small, flat-tipped screwdriver to gently move the switch

Control module operation switches

Reserved for future use.


Auto on (available for aircraft powered headset versions only):
Set at the factory to enable the auto-on function. The headset will turn on when aircraft power is available. To disable auto on, set the switch to off. With the switch in the off position, the user must manually turn the headset on.


Aircraft audio:
Set the sensitivity of intercom audio to Normal or Low (-12 dB).


Intercom (available for headset configurations that support two-channel or stereo intercom systems only):
For most configurations, set at the factory for mono audio systems (to provide audio in both ears). Set it to stereo (ST) if your aircraft has a stereo intercom.


Auto off:
Set at the factory to enable the auto-off function. The headset will turn off after three to nine minutes of inactivity. To disable auto off, set the switch to off. With the switch in the off position, the user must manually turn the headset off.


Tap control:
By default, Tap control is disabled. With Tap control turned on, you can double-tap an earbud to toggle that earbud's noise cancellation mode between Low and the control module Acoustic Noise Cancellation switch setting.
