For best protection, ear cushion sealing rings should seal firmly against head. Anything
that interferes with the seal — such as long hair (pull back to the extent possible),
thick or poorly fitting eyeglass temples, pencils or caps — will lessen the protection.
Do not bend or reshape the headband, as this will cause a loose fit and sound leakage.
Earmuffs must be regularly inspected for cracks or worn parts and replaced as needed.
Typical life for foam cushion sealing rings is six months.
Clean the exterior of the hearing protector regularly with soap and warm water.
Do not immerse in water.
Do not store the hearing protector behind a windshield or at temperatures
above 131°F (55°C).
Certain chemical substances may damage this product. Contact the manufacturer
for more information.

If instructions are not followed, bodily injury may result or protection may be severely affected.
When interference increases or the sound level becomes too weak, it is time to change the batteries.
Do not store with the batteries installed. A leaking battery may cause bodily injury or damage to the
hearing protector.
These hearing protectors help reduce exposure to hazardous noise and other loud sounds. Misuse or
failure to wear hearing protectors at all times when you are exposed to noise may result in hearing
loss or injury.
If there is any drainage from your ear or if you have a hole in your eardrum, consult with your
physician before wearing hearing protection. Failure to do so may result in hearing loss or injury.
