Auto-Off power feature does not work | Bose A30 Aviation Headset
Check the position of the AUTO-OFF switch in the headset control module.
In the battery compartment on your headset control module, there is a switch to turn on or off the automatic power off feature of your headset. Check that this switch is set appropriately. For more info, see Setting operation switches in your headset control module.
Connect the headset to a different panel jack or, if possible, to another aircraft.
Non-TSO equipment, worn jacks/loose connections, or incorrectly wired jacks (i.e. reversed stereo or mic / ground wires) in the aircraft can cause issues. If available, try connecting the headset to another jack in the aircraft or to jacks in a separate aircraft. If the headset works fine when connected elsewhere, the panel jack or wiring to the jack is the issue.
Determine if the headset turns off when disconnected from the aircraft.
With Auto-Off enabled, the headset will turn off within 3 to 9 minutes after being disconnected from the aircraft. (Note: If disconnected from the aircraft but connected via Bluetooth® to a phone call, the headset will turn off 3 minutes after the phone call is ended.) If the headset does not turn off after 9 minutes while disconnected from the aircraft, there is an issue with the headset; however, if the headset does turn off, there is an issue at the panel connection.
