• Only use approved and compatible 3M™ PELTOR™ Communications Eartips.
• If the requirements above are not adhered to, the protection afforded by the earplugs will be severely impaired.

2.2. CAUTION
• Risk of explosion if battery is replaced by an incorrect type.
•
With Lithium ion batteries, there is a risk of fire and burns.
Do not open, crush, heat above 122°F/50°C, or incinerate.
• Do not charge batteries in temperatures above 113°F/45°C
or below 32°F/0°C.
• For greater comfort and safety when using the
three-flange
3M UltraFit Communication Eartips, remove the eartip slowly
with twisting motion to gradually break the seal.
•
Always use product-specific 3M replacement parts. Use of
unauthorized replacement parts may reduce the protection
you receive from this product.
2.3. NOTE
• When worn according to these 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 earplug 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.
• If using an external power supply for charging the earplugs,
only connect to a listed power supply certified to IEC/UL/
CSA 62368-1 or an equivalent local safety standard. The
power supply shall have a rated output of 5Vdc, 200mA
(minimum).
2.4. U.S. EPA REQUIRED STATEMENTS
Improper fit of this device will reduce its effectiveness in
attenuating noise. Consult the enclosed instructions for
proper fit.
Although hearing protectors can be recommended for
protection against the harmful effects of
impulsive
noise, the
Noise Reduction Rating (NRR) is based on the attenuation of
continuous
noise and may not be an accurate indicator of the
protection attainable against
impulsive
noise such as gunfire.
The level of noise entering a person’s ear, when hearing
protector is worn as directed, is closely approximated by the
difference between the A-weighted environmental noise level
and the NRR.
Example:
1. The environmental noise level as measured at the ear is
92 dBA.
2. The NRR is 30 decibels (dB).
3. The level of noise entering the ear is approximately equal to
62 dB(A).
CAUTION:
For noise environments dominated by frequencies
below 500 Hz the C-weighted environmental noise level should
be used.
