1. INTRODUCTION
Congratulations and thank you for choosing 3M™ PELTOR™ protective communication solutions! Welcome to the next
generation of protective communication.
1.1. INTENDED USE
These 3M™ PELTOR™ headsets are intended to help protect against hazardous noise levels and loud sounds while allowing
the user to hear the surroundings via the ambient/environmental microphones, listen to connected communication devices, and
communicate face-to-face with integrated Natural Interaction Behavior (NIB) Technology in high levels of steady state noise. It is
expected that all users read and understand the provided user instructions as well as be familiar with the use of this device.
2. SAFETY
2.1. IMPORTANT
Please read, understand, and follow all safety information in these instructions prior to use. Retain these instructions for future
reference. For additional information or any questions, contact 3M Technical Services. Refer to contact information listed on
the last page of this manual.
• 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:
• 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.
• 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:
• 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 for guidance on how to adjust attenuation label values.
It is recommended that the NRR be reduced by 50% to better estimate typical protection.
• 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.
• DO NOT use the headset in Earplug Mode without properly fitted earplugs under the earcups, as the increase in audio volume
may reach an unsafe level. Failure to wear properly fitted earplugs while operating in Earplug Mode may result in hearing loss or
injury.
• 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 or neckband, 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 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,
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.
