!
WARNING
To reduce the risk of igniting an explosion which, if not

• Ensure that the 3M™ PELTOR™ Headset and any
intrinsically safe accessories are only used and stored in
the classified areas consistent with the marked equipment
ratings.
• Never connect electronic components or devices to the
headset in a potentially explosive environment.
• Only connect to the headset the 3M™ PELTOR™ Spare
Parts and Accessories listed in the user instructions.

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.
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.
Failure to follow these instructions may reduce the
protection provided by the earmuff and may result in
hearing loss:
a. 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.
h. If the requirements above are not adhered to, the
protection afforded by the earmuffs will be severely impaired.
EN 352 Safety Statements:
• The fitting of hygiene covers to the cushions may affect the
acoustic performance of the earmuffs.
• This product may be adversely affected by certain chemical
substances. Further information should be sought from the
manufacturer.
• These 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' ear-muffs
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.
CAUTION:
• For noise environments dominated by frequencies below
500 Hz the C-weighted environmental noise level should
