Inserting and replacing the batteries

Caution: If the batteries do not fit correctly, do not force them in. Forcing an

improper connection will cause permanent damage to the control

module.

Turn off headset power.

Press down firmly on the battery compartment cover and slide the cover to

release. The battery door is tethered. Do not detach the door from module.

Insert two alkaline AA batteries into the control module, observing proper

polarity.

Replace the battery compartment cover.

Warning: Replace batteries with alkaline batteries only. Do not use any other

battery chemistries.

Note: For aircraft-powered versions (5-pin XLR, 6-pin, 8-pin) batteries are not

required for operation if aircraft power is available.

The headset can be configured to either plug into aircraft power or rely entirely on

battery power.

A single 6-pin plug inserted into the 6-pin connector provides the headset with

aircraft power and intercom audio.

If your headset is aircraft-powered, a 6-pin connector may be installed and mount-

ed to an aircraft panel. See "Mounting the aircraft panel connector" on page 35.

Note: An adapter is available from Bose to convert a 6-pin connector to a dual G/A

or U174 plug for additional connection flexibility for users who fly multiple

aircraft and require other connector types.

To connect the headset

Align the 6-pin plug to the connector keyway by matching the narrow bar on the

plug to the slot on the connector.

Firmly press the plug into the connector jack.

Align keyway
