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.
