REPARING THE

EADSET FOR

The battery compartment

The Bose

A20™ Aviation 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. If you do not

want to change any of the operation switches, skip ahead to "Inserting and

replacing the batteries" on page 10.

You must open the battery compartment to access the operation switches.

Press down firmly on the battery compartment cover finger indent and slide the

cover down. The cover is tethered to the module. Do not attempt to detach it.

Note: The battery compartment cover is designed to remain securely closed. You

may need to use additional force when pressing down and releasing cover.

The operation switches control the Auto Off function and whether you hear

audio in one or both ears.

Operation switches

To change the operation switches

1. Open the battery compartment.

2. If batteries are installed, remove them.

In the battery compartment, you can observe and change the switch positions.
