INTENDED USE:
The Tactix earmuff is designed to help reduce exposure to loud sounds and hazardous noise levels produced
during activities such as using power tools, lawn mowers, leaf blowers and vacuums. For very loud sounds or
higher noise levels Tactix recommends wearing earplugs in addition to the earmuffs for additional noise
reduction.
Hearing protection should be suitable for the application, worn for the duration of the noise exposure, fitted
correctly and replaced when necessary.
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.
Place the earmuff on the head with the band at the crown (top) of the head.
Pull the cups apart and place the earmuff over your ears so that the ear cushions fit snugly to form a seal.
It is important that the cups fully enclose the ears and that the cushions exert equal pressure
around the ears.
Adjust the height of both cups for comfort while holding the headband in place.
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.
Do not bend or reshape the headband, as this will impact the fit and effect the noise reduction performance.
Do not store the hearing protection device at temperatures above 50 degrees Celsius.
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.
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 of your environment.
For Example: An environmental noise level of 90dB measured at the ear, with SNR 26dB protection device
worn the level of noise entering the ear is approximately 64dB.
The sound attenuation values for the hearing protection device are measured in accordance with EN24869-1.
