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).

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. 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, 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,

WARNING
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 backband, 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. Ensure that you have positioned the external input cable
correctly when using the backband version, to avoid a potential
reduction of sound attenuation and hearing protection. Refer to
illustration D:9 and D:10.
i. Do not use the headset in ear-plug mode without properly fitted
earplugs under the earcups, as the increase in audio volume
may reach an unsafe level.
CAUTION:
• Risk of explosion if battery is replaced by an incorrect type.
• 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 hearing
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).
• Operating temperature range: –20 °C (–4 °F) to 55 °C (131 °F)
• Storage temperature range: –20 °C (–4 °F) to 55 °C (131 °F)
• Weight of hearing protector: MT20H682FB-**N** = 351 g,
MT20H682BB-**N** = 313 g, MT20H682FB-**N**(HY80) = 390 g,
MT20H682BB-**N**(HY80) = 324 g
• Shelf life: 5 years, excluding batteries.
