headband rests on the top of the head to support the muffs. 3 Make sure that the headband is evenly adjusted, left to right. The
ear cushion should be a snug fit against the head. 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.
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 continuousnoise

INFORMATION REQUIRED BY EPA.
The level of noise entering a person’s 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. The EF3S82 features an electronic amplification mechanism that clarifies low
pitch sounds, but shuts down within milliseconds when sounds above 85dB occur.
Instructions for Operation.1Turn the switches to the ON position. 2 Place the EF3S82
