WARNINGS

Read, understand, and follow these instructions to ensure safe

operation. Keep these instructions for future reference.

These hearing protectors help reduce exposure to hazardous noise and other

loud sounds. Misuse or failure to wear hearing protection at all times that you

are exposed to noise may result in hearing loss or injury.

• Inspect earmuffs before each use; damage to the earmuffs can reduce noise

reduction performance.

• Improper fit of this device will reduce its effectiveness in attenuating noise.

Consult the FITTING/ADJUSTMENT section for proper fit.

• Avoid overprotection in minimal noise environments: using noise reduction

equipment can reduce awareness of the surrounding environment.

MAINTENANCE

STORAGE: Regularly inspect earmuffs and ear cushions for excessive

wear such as tears and/or visible cracks. Do not reshape the wire arms as

this will cause a loose fit and reduce noise reduction rating.

Replace earmuffs if tears and/or cracks are visible on the shell and/or

cushion. Replace earmuffs if there is a noticeable change in the fit and

no longer seal firmly against your head.

CLEANING: The earmuff shell and cushion can be gently wiped clean with

lukewarm mild soapy water and dried with a soft cloth without rubbing.

Do not submerge earmuffs in water or treat with abrasive cleaners or

solvents.
