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.
1. Turn off headset power.
2. 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.
3.
Insert two alkaline AA batteries into the control module, observing proper
polarity.
4.
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.

Connecting the headset to the aircraft

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

Using the 6-pin plug

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
mounted 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.
