 Preparing the Headset for Use

This table shows possible positions, default setting, and purpose for each 

 operation  switch.

PRIORITY
(Available for 
Bluetooth

®

 

 headsets  only)

Establishes priority between two secondary audio 

 sources. Select BT to give the Bluetooth (wireless) 

connection higher priority. Select AUX to give the wired 

connection higher priority. 
See “Setting the Priority (BT-AUX) switch” on page 25.

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 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 OFF position, the user must manually turn the 

headset on.

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 OFF position, the user must manually turn the 

headset off.

With aircraft powered versions (5-pin XLR, 6-pin, and 8-pin) the headset will turn 

on automatically when aircraft power is available. If you do not want the headset to 

turn on automatically, set the switch position to OFF.

The Auto Off feature detects when the headset is not in use and shuts it off after 

several minutes to preserve battery power. The exact time it takes to shut off varies 

and can range between three to nine minutes after you stop using the headset.
When the headset is running on battery power and is not plugged in to a  powered 

intercom, it will shut off, unless there is an active AUX audio source  present.
If you are on a phone call and unplugged from the intercom, the headset will allow 

you to complete your call, then it will turn off approximately three minutes after the 

call is ended.
