3M™ PELTOR™ ComTac™ VI NIB Headset
MT20H682**-**N**
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
protection against hazardous noise levels and loud sounds
while allowing the user to hear the surroundings via the
ambient/environmental microphones, listen to connected
communication devices and communicate face-to-face with
integrated Natural Interaction Behavior (NIB) Technology in high
levels of steady state noise. 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 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 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 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.
All manuals and user guides at all-guides.com
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 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:
• LDF and NIB: 30 hours
• LDF: 50 hours
• This product may be adversely affected by certain chemical
substances. Further information should be sought from the
manufacturer.
• These earmuffs are of small 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.
• The product is not suited for high continuous low frequency
noise levels.
CAUTION:
• Risk of explosion if battery is replaced by an incorrect type.
• 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 hearing
protector helps reduce exposure to both continuous noises,
such as industrial noises and noises from vehicles and aircraft,
