Headset Care and Maintenance 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 access cover replacement Replace the microphone assembly or connector access 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. 28 - English
