5 Before Use Headset Warnings

5.1

Hearing Protector Warnings

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, read user instructions, talk to your supervisor or call 3M™ Technical Service. 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:
• 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:
• 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.
• 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.
• Inspect the hearing protector before each use. If damaged, select an undamaged hearing protector or
avoid the noisy environment.
• 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.
• Do not bend or reshape the headband, and ensure there is adequate force to hold the earmuffs firmly
in place.
• 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.
• The radio level may be above 82dB(A) if the volume control is set a high level. Adjust the audio volume
to the lowest acceptable level.

5.2 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 performance. 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 distortion or failure is detected, the wearer should refer to the manufacturer's advice.
• The hearing protector limits the entertainment audio level to 82dB(A).
