®
microphones. It is expected that all users read and
understand the provided user instructions as well as be
familiar with the use of this device.

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 correct use, consult
supervisor and User Instructions, or call 3M Technical
Services. 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.
Failure to follow these instructions may result in serious
injury or death:
a. Listening to music or other 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. The audibility of warning signals at a specific
workplace may be impaired while using the entertainment
facility.
b. To reduce the risks associated with igniting an explosion,
do not use this product in a potentially explosive atmosphere.
Failure to follow these instructions may reduce the
protection provided by the earmuff/earplug and may
result in hearing loss:
a. 3M Research suggests that users may receive less noise
reduction than indicated by the attenuation value(s) on the
packaging due to variation in fit, fitting skill, and motivation of

the user. Refer to your applicable regulations for guidance on
how to adjust label values and estimate attenuation. In
addition, 3M strongly recommends fit testing of hearing
protectors.
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 or neckband, 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.
g. The output of the electrical audio circuit of this hearing
protector may exceed the daily limit sound level. Adjust the
audio volume to the lowest acceptable level.
EN 352 Safety Statements:
• 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 18 hours.
• This product may be adversely affected by certain chemical
substances. Further information should be sought from the
manufacturer.
• These neckband earmuffs are of large size range.
Earmuffs complying with EN 352-1 are of "medium size range"
or "small size range" or "large size range". "Medium size
range" earmuffs will fit the majority of wearers. "Small size
range" or "large size range" earmuffs are designed to fit
wearers for whom "medium size range" earmuffs are not
suitable.
• These helmet mounted earmuffs are of "large size range".
Helmet mounted earmuffs complying with EN 352-3 are of
"medium size range" or "small size range" or "large size
range". "Medium size range" helmet mounted earmuffs are
designed to fit the majority of wearers. "Small size range" or
"large size range" helmet mounted earmuffs are designed to fit
wearers for whom "medium size range" helmet mounted
earmuffs are not suitable.
