Fitting Instructions

Improper fitting of this hearing protection device will reduce its effectiveness. Fit your earmuff correctly before any exposure to noise and replace if the earmuff is damaged.

Important: For a proper fit, ear cushions should seal firmly against the head. Anything that interferes with the seal, such as long hair, thick eyeglasses, pens, or caps, will lessen the earmuff's effectiveness.

Care and Cleaning

Sponge clean with warm, soapy water on the ear cushions only. Do not use solvents. Ensure the ear cushion is completely dry before use. Earmuffs must be regularly inspected for cracks or worn parts and replaced as needed. The earmuffs must not be immersed in water!

Noise Attenuation (Reduction)

Noise exposure over 80 decibels (dB) may cause permanent hearing loss. Ensure the hearing protection device selected meets the needed noise attenuation for your environment.

For Example: An environmental noise level of 90 dB measured at the ear, with an SNR 29 dB protection device worn, the level of noise entering the ear is approximately 61 dB.
