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
and/or an external radio and hear the surroundings via the
ambient microphones.
The WS TM models also provide Bluetooth
is expected that all users read and understand the provided
user instructions as well as be familiar with the use of this
device.

IMPORTANT

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.
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. U.S. EPA specifies the NRR as the measure of hearing
protector noise reduction. However, 3M makes no warranties

WARNING
* Only WS
as to the suitability of the NRR for this purpose. 3M strongly
recommends personal fit testing of hearing protectors.
Research suggests that users may receive less noise
reduction than indicated by the attenuation label value(s) on
the packaging due to variation in fit, fitting skill, and motivation
of the user. Refer to applicable regulations for guidance on
how to adjust attenuation label values. It is recommended that
the NRR be reduced by 50% to better estimate typical
protection.
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.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.
Sound levels from any connected external device such as
2-way radios and phones may exceed safe levels and must
be appropriately limited by the user. Always use external
devices at the lowest sound level possible for the situation and
limit the amount of time you are exposed to unsafe levels as
determined by your employer and applicable regulations. If
your hearing seems dulled or you hear a ringing or buzzing
during or after any sound exposure (including gunfire), or for
any other reason you suspect a hearing problem, go to a quiet
environment immediately and consult a medical professional
and/or your supervisor.
g. 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).
• Use only 3M™ PELTOR™ Battery ACK081 charged with
cable 3M™ PELTOR™ AL2AI connected to a 3M™ PELTOR™
Power supply FR08.
• With Lithium-ion 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.
