IMPORTANT
Please read, understand, and follow all safety information in these instructions prior to use. Retain these instructions for
future reference. For additional information or any questions, contact 3M Technical Service (contact information listed on
the last page).
WARNING
This hearing protector helps reduce exposure to hazardous noise and other loud sounds. Misuse or failure to wear
hearing protection at all times when exposed to hazardous noise may result in hearing loss or injury. For
proper use, see supervisor, User Instructions or call 3M Technical Service. If your hearing seems dulled or you hear a
ringing or buzzing during or after any noise exposure (including gunfire), or for any other reason you suspect a hearing
problem, leave the noisy environment immediately and consult a medical professional and/or your supervisor.
WARNING
Failure to follow these instructions may result in serious injury or death:
Listening to audio communication may reduce your situational awareness and ability to hear warning signals. Stay alert
and adjust the audio volume to the lowest acceptable level.
Failure to follow these instructions may reduce the protection provided by the earmuff and may result in hear-
ing loss:
a. 3M strongly recommends individual fit testing of hearing protectors. If the NRR or SNR is used to estimate typical
workplace protection, 3M recommends that the noise reduction value be reduced by 50% or in accordance with ap-
plicable regulations.
b. Ensure the hearing protector is properly selected, fit, adjusted, and maintained. Improper fit of this device will
reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit.
c. Inspect the hearing protector before each use. If damaged, select an undamaged hearing protector or avoid the
noisy environment.
d. When additional personal protective equipment is necessary (e.g. safety glasses, respirators, etc.), select flexible,
low profile temples or straps to minimize interference with the earmuff cushion. Remove all other unnecessary articles
(e.g. hair, hats, jewelry, headphones, hygiene covers, etc.) that could interfere with the seal of the earmuff cushion and
reduce the protection of the earmuff.
e. Do not bend or reshape the headband, and ensure there is adequate force to hold the earmuffs firmly in place.
f. Earmuffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for
cracking and leakage, for example. When used regularly, replace the ear cushions and foam liners at least twice a year
to maintain consistent protection, hygiene, and comfort.

• The output of the level-dependent circuit of this hearing protector may exceed the external sound level.
• The fitting of hygiene covers to the cushions may affect the acoustic performance of the earmuffs.
• Performance may deteriorate with battery usage. The typical period of continuous use that can be expected from
the earmuff battery is approximately 20 hours.
• This product may be adversely affected by certain chemical substances. Further information should be sought from
