Problem

Low rumbling sound with

headset turned on in a

quiet environment

Crackling sound audible

with headset turned on in a

loud environment, or ANR

is intermittent.

No active noise reduction and

no communication

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, battery, battery cover,

wind screen, 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 General Care and Maintenance.

What to do

• Adjust the earcup fit to create a better seal on the head.

The headset's low-force design makes it sensitive to

items that interfere with the seal around the ear.

Ensure that the ears are completely inside the ear

cushions and that items such as 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. If the ear cushion has surface tears, torn

stitching joints, large wrinkles, or a surface which has

become dried and stiff, replace the ear cushions.

• Adjust the earcup fit to eliminate the sound. See

Wearing the Headset.

• If battery powered, check to see if the battery is low, red

light is on.

• If aircraft powered, check 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,

without gaps. If the ear cushion has surface tears, torn

stitching joints, large wrinkles, or a surface which has

become dried and stiff, replace the ear cushions.

• Check boom microphone cable connection on the

bottom of the earcup.
