Instructions for Operation.

The level of noise entering a persons ear, when Hearing protector is worn as directed, is closed approsimately by the difference between the A-weighted environmental noise and the NRR.These specially deisgned over-ear hearing protectors not only protect your hearing from loud sources such as gunfire, but also allow you to hear normal conversation, range commands, even the sound of game in the woods.

For noise environment dominated by frequencies below 500Hz, the C-weighted environmental noise level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing protection can be recommended for protection against the harmful effects of impulse noise, the Noise Reduction Rating is based on the attenuation of continuous noise.
INFORMATION REQUIRED BY EPA.

4. Make sure to get as little air as possible between the ear cushions and your head. Muffs should be cleaned regulary with soap and water.
CAUTION.

3. Make sure that the headband is evenly adjusted, left to right. The ear cushion should be a snug fit against the head.
