Congratulations and thank you for choosing this
communication solutions headset!
1.1. INTENDED USE
These headsets are intended to provide workers with
protection against hazardous noise levels while allowing the
user to communicate with built-in Bluetooth technology and
hear the surroundings via the ambient microphones. It is
expected that all users read and understand the provided user
instructions as well as be familiar with the use of this device.
3M PSD products are occupational use only.
In Europe, some 3M PELTOR products may also be
appropriate for certain non-work uses. Always read and follow
User Instructions.
1.2. CARRIER
The word carrier used in this document refers to head
protection, face protection and/or non-protective devices.
2. SAFETY

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. This hearing protector provides an entertainment audio
facility. Listening to music or other audio communication may
reduce your situational awareness and ability to hear warning
signals at a specific workplace. 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 non-intrinsic safe products and accessories 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 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 and guidance on
how to adjust attenuation label value(s). In the absence of
applicable regulations, it is recommended that the attenuation
label value(s) be reduced to better estimate typical protection.
b. U.S. EPA specifies the NRR as the measure of hearing
protector noise reduction. However, 3M makes no warranties
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 and guidance on
how to adjust attenuation label value(s). It is recommended
that the NRR be reduced by 50% to better estimate typical
protection.
c. 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.
d.
Inspect the hearing protector before each use. If
damaged, select an undamaged hearing protector or avoid the
noisy environment.
e. 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.
f. Do not bend or reshape the headband or neckband, and
ensure there is adequate force to hold the earmuffs firmly in
place.
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.
h.
If the requirements above are not adhered to, the
protection afforded by the hearing protectors will be severely
impaired.
EN 352 Safety Statements:
•
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 75 hours.
• This product may be adversely affected by certain chemical
substances. Further information should be sought from the
manufacturer.
• These earmuffs attached to head protection and/or face
protection devices are of large size range. Earmuffs
attached to head protection and/or face protection devices
complying with EN 352-3 are of ‘medium size range’, ‘small
size range’ or ‘large size range’. ‘Medium size range’
earmuffs will fit the majority of users. ‘Small size range’ or
‘large size range’ earmuffs are designed to fit users for
whom ‘medium size range’ earmuffs are not suitable.
• The output of the audio circuit of this hearing protector may
exceed the exposure limit level.
• The entertainment audio signal does not exceed 82 dB(A).
The maximum SPL is 77,6 dB(A) at – 10 dBFS.
