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.

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 earmuffs 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. 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. 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.
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.
