CAUTION: Do not attempt to disassemble or service the inside of the earcups or other parts of
the headset. Only the boom microphone cable, connector access cover, batteries, battery
cover, windscreen, and ear cushions are replaceable by the user. For instructions on how to
care for the headset and how to replace the ear cushions, refer to "Headset Care and Mainte-
nance" on page 25.
• If your aircraft has a mono audio system, verify that the stereo/
mono configuration switch is set to mono. See "Changing the
optional operation switches" on page 13. If the switch is set to
stereo, and the headset is plugged into a mono audio system,
you will hear only through the left earcup.
• Check to see if the protective inner screen is damaged.
• Adjust the earcup fit to create a better seal on your head. The
headset's low-force design makes it sensitive to items that
interfere with the seal around your ear. Make sure that your
ears are completely inside the ear cushions, and that a hat or
eyeglasses with thick temples do not interfere with the seal.
• Check ports at the outside surface of each earcup to ensure
they are not blocked. If dust or dirt is present, carefully remove
the debris using tweezers. Do not blow out or vacuum debris.
• Inspect the seal between the ear cushion skirt and the earcup.
The skirt should enclose the earcup evenly, without gaps.
Replace any cushions that have surface tears, torn stitching
joints, large wrinkles, or have become dried and stiff.
• Adjust the earcup fit to eliminate the crackling sound. Refer to
"Wearing it properly" on page 19.
• If your headset is battery powered, check to see if the battery is
low (indicated by fast blinking red LED).
• If your headset is aircraft powered, make sure that the voltage
powering the headset is greater than 10 VDC.
• Inspect the seal between the ear cushion skirt and the earcup.
The skirt should fit into the slot on the earcup with no gaps.
Replace any cushions that have surface tears, torn stitching
joints, large wrinkles, or have become dried and stiff.
• Check boom microphone cable connection on the bottom of
the earcup.
