IMPORTANT USER INFORMATION
The headset must be worn, adjusted, cleaned and maintained in accordance with this manual. As with any hearing
protector, incorrect use or failure to follow the instructions supplied with this product could result in permanent disability due
to exposure to noise.
NOTICE! 100% use of a proper hearing protector is the only certain protection from hearing loss.
In environments with more than 82 dB A-weighted noise level, you need to protect your hearing. The hearing receptors in
your inner-ears may be irreparably damaged if you lift a cup of your hearing protectors for even a very short time in a noisy
environment.
The use of a comfortable hearing protector, designed for the specific noise level in which it is used, is the best guarantee to
that you will wear the hearing protector 100% of the time to protect yourself from permanent hearing loss.
For best protection, brush aside excess hair around your ears so the cushions fit snugly on your head. The arms/bands of
any spectacles or goggles worn should be as thin as possible to allow the hearing protector to fit closely to the head.
MAINTENANCE / CLEANING
After prolonged use, or other situations in which the headset attracts moisture inside the cups, remove the cushions and
inserts to allow the hearing protector to dry before its next use.
Do not store the headset in temperatures exceeding +55°C, for example on a car dashboard/hat shelf or window sill.
The headset (especially the ear cushions) can eventually wear out. Inspect regularly for signs of any physical damage and
replace if necessary. Certain chemical substances may be harmful to this product. Contact 3M for more information.
Clean/disinfect the shells, headband and ear cushions regularly with soap and warm water. Notice! Do not immerse in
water or fluids.
