Wearing the Headset
(Note: If mounting the headset to the helmet with the optional Rail Mounting Kit,
please see instructions beginning on page X.)
1. Identify the left and right ear seals. The Power/Volume buttons are on the left
ear cup.
2. Place the headset over the head.
3. Adjust ear cup height by pulling or pushing on the cups until the ear seals are
securely positioned over the ears. Adjustment is accomplished by extending and
contracting the ear cup frames on either side of the ear cups while holding the
headband in place.
4. For effective sound protection, be sure that the ear seals are completely sealed
around the ear and obstacles such as hair, jewelry, or clothing are out of the way.
