MAINTENANCE AND CLEANING

For your headset to perform properly, always comply

with the following:

1. Never alter or modify your headset. If you re-form the headband or muff, cut

or punch holes in the ear seal, drill or punch holes in the ear cup insert, paint

or coat the device, you will seriously jeopardize the hearing protection it

affords and hearing damage could occur.

2. Use of ear seals, other than those supplied by David Clark Company, may

adversely affect both your comfort and the headset’s overall performance.

3. Seek repair or replacement of the headset immediately if you see a defect,

such as any sign of cracks or splits in domes, ear seals, headbands, or

other parts.

4. Storage in direct sunlight or at high temperatures, or cleaning in non-

recommended cleaning solutions, may shorten the useful life of the headset.

5. Each individual’s body chemistry is different. Perspiration, body oils, and hair

grooming cosmetics may affect materials; loss in elasticity or softness of ear

cup seals and of the foam pads inside ear cups may result. Replace parts

immediately if these signs of wear occur.

Cleaning Instructions:

1. Headpad cover can be removed for washing. Ear seals can be removed and

cleaned using mild soap and water. Be sure to dry thoroughly.

2. DO NOT SUBMERGE IN WATER!

Alert: Do Not Use Comfort Covers. Your headset came with form

fitted ear seals. Do not use “comfort covers” of any kind.

Any disruption to the seal around the ears will result in

the reduction of effectiveness in the ENC performance.
