Tools Required:
1 - Small size Phillips Screwdriver

Procedure:
1. Make sure power is off and remove the
battery.
2. Remove the Ear Pad and Ear Cup.
3. Remove three screws from the Inner Case.
4. Separate the case halves by pulling the Inner
Case down, then apart at the bottom.
Carefully raise the Inner Case just over the
On-Off Button and slide down slightly to
separate. Support the Inner Case so the
speaker cable is not strained.
5. Disconnect the power connector located at the
top of the Main PWA.
6. Carefully pull the power wires out of the top
groove of the Headband Clip as shown in
illustration.
7. Remove the Headband Clip from the
Headband end by rotating it 90 degrees and
pulling it free of the headband.
8. Pull the Headband Assembly and cable out of
the Outer Case.

11. Grasp Headband Clip with open wire groove
up and side slot facing Headband. Insert on
Headband and rotate 90 degrees in place.
12. Carefully press the power wires, one on top of
the other, into the open wire groove of the
Headband Clip. Be sure to press the wires
completely down into the wire groove.
13. Plug the power cable into the connector
located at the top of the PWA. Route the
power cable between the On-Off Button and
the large capacitor on the PWA. The power
cable MUST route down the center of the
PWA or the Headband will not extend
properly.

of the two connectors located near the bottom
of the Main PWA.
15. Assemble the case halves by inserting the tab
at the top of the Inner Case through the slot at
the top of the Outer Case and carefully lower
the Inner Case over the On-Off Button and
snap it shut at the bottom. Care must be taken
not to pinch any wires.
