3M PELTOR WS LiteCom Pro III MT73H7 4D10EU Series Manual page 3

WARNING
Failure to follow these instructions may result in
serious injury or death:
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.
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 dam-
aged, select an undamaged hearing protector or avoid the
noisy environment.
d. When additional personal protective equipment is nec-
essary (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. 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.

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 up to 12-16 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 352-3 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.
• This foldable ear-muff is of large size range. Ear-muffs
complying with EN 352-1 are of medium size range or
small size range or large size range. Medium size range
ear-muffs will fit the majority of wearers. Small size range
or large size range ear-muffs are designed to fit wearers
for whom medium size range ear-muffs are not suitable.
• With Lithium ion batteries, there is a risk of fire and
burns. Do not open, crush, heat above 55°C (131°F),
or incinerate.
CAUTION:
Risk of explosion if battery is replaced by an incorrect type.
NOTE
• When worn according to the 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 perfor-
mance. To learn more about hearing protection for impulse
noise, visit www.3M.com/hearing.
• This earmuff is provided with level-dependent attenuation.
The wearer should check correct operation before use. If
distortion or failure is detected, the wearer should refer to the
manufacturer's advice for maintenance and replacement of
the battery.
• This earmuff is provided with electrical audio input. The
wearer should check correct operation before use. If distor-
tion or failure is detected, the wearer should refer to the
manufacturer's advice.
• This hearing protector limits the entertainment audio signal
to 82 dBA effective to the ear.
