Headband cushion replacement
The headband cushion is designed to give the maximum level of comfort to your
headset.
Bose recommends that you replace the cushion after regular care and maintenance
fails to restore the wool pile to its original size and shape.
To replace the cushion:
1. On a protected surface, turn the headset upside down. Remove the old
cushion from the headband.
2. While still holding the headband open, align the center of the new cushion
with the center of the headband and press firmly from the center toward the
outside.
Microphone assembly or terminator cover replacement
Replace the microphone assembly or terminator cover as described in
“Attaching the microphone assembly” on page 10.
Storage
• Store the headset in a ventilated area away from direct sunlight.
• Remove the batteries before storing the headset for extended periods.
