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 proper use, see
supervisor, 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 gunre), 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 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.
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 personal t 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 t, tting 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.
EN
b. Ensure the hearing protector is properly selected, t,
adjusted, and maintained. Improper t of this device will
reduce its effectiveness in attenuating noise. Consult the
enclosed instructions for proper t.
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
exible, low prole 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 rmly 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 gunre), 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 earmuffs will be severely impaired.
EN 352 Safety Statements:
• The tting of hygiene covers to the cushions may affect the
acoustic performance of the earmuffs.
• 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 t the majority of users. ‘Small size range’ or
‘large size range’ earmuffs are designed to t users for
whom ‘medium size range’ earmuffs are not suitable.
• The wireless connection of this product may not be used for
entertainment audio since the output level is not limited to
the necessary innocuousness level.
