Introduction
Congratulations and thank you for choosing 3M™ PELTOR™
Communication Solutions! Welcome to the next generation of
protective communication.
Intended Use
These 3M™ PELTOR™ headsets are intended to provide
workers with protection against hazardous noise levels and
loud sounds while allowing the user to communicate with
built-in Bluetooth . It is expected that all users read and
®
understand the provided user instructions as well as be
familiar with the use of this device.
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
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 58 hours.
• This product may be adversely affected by certain
chemical substances. Further information should be
sought from the manufacturer.
• The helmet mounted earmuffs are of large size range.
Earmuffs complying with EN 352-1 and EN 352-3 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.

WARNING
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 and may result in
hearing 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
applicable 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.
g. If the recommendations above are not adhered to, the
protection afforded by the ear-muffs will be severely
impaired.
CAUTION
To reduce the risks associated with fire, explosion and
burns, which if not avoided, could result in minor or
moderate injury or property damage:
a. Use only 3M™ PELTOR™ USB charger FR09 EU and
3M™ PELTOR™ USB wall adapter FR08 with 3M™
PELTOR™ LR6NM rechargeable batteries (or equivalent AA
Ni-MH rechargeable batteries.)
b. The battery may not be charged if the ambient temperature
exceeds +45°C +113°F
CAUTION:
Risk of explosion if battery is replaced by an incorrect type.
