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
while allowing the user to communicate with built-in two-way
radio. All users must 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 Services (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 hear-
ing 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 Ser-
vices. 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.
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 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, ad-
justed, 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,
8
select an undamaged hearing protector or avoid the noisy
environment.
d. When additional personal protective equipment is neces-
sary (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.
CAUTION:
• Risk of explosion if battery is replaced by an incorrect type.
• Do not charge batteries in temperatures above 45°C
(113°F).
• Only use the 3M™ PELTOR™ Power Supply FR08 when
recharging the battery.
• With batteries, there is a risk of fire and burns. Do not open,
crush, heat above 55°C (131°F), or incinerate.
• For noise environments dominated by frequencies below
500 Hz the C-weighted environmental noise level should be
used.
• Always use product-specific 3M replacement parts. Use of
unauthorized replacement parts may reduce the protection you
receive from this product.
NOTE
• When worn according to these User Instructions, this hear-
ing protector helps reduce exposure to both continuous noises,
such as industrial noises and noises from vehicles and aircraft,
as well as very loud impulse noises, such as gunfire. It is
difficult to predict the required and/or actual hearing protection
obtained during exposure to impulse noises. For gunfire, the
weapon type, number of rounds fired, proper selection, fit and
use of hearing protection, proper care of hearing protection,
and other variables will impact performance. To learn more
about hearing protection for impulse noise, visit www.3M.com/
hearing.
• Although hearing protectors can be recommended for
protection against the harmful effects of impulsive noise, the
Noise Reduction Rating (NRR) is based on the attenuation of
continuous noise and may not be an accurate indicator of the
protection attainable against impulsive noise such as gunfire
(wording required by EPA).
• In Canada, users of hard hats combined with earmuffs must
refer to CSA Standard Z94.1 on industrial protective headwear.
• Operating temperature range: -4°F (-20°C) to 131°F (55°C)
• Storage temperature range: -4°F (-20°C) to 131°F (55°C)
