• In Canada, users of hard hats combined with earmuffs must
refer to CSA Standard Z94.1 on industrial protective
headwear.
LABORATORY ATTENUATION
WARNING! 3M strongly recommends individual fit testing
of hearing protectors. If the NRR is used to estimate
typical workplace protection, 3M recommends that the
noise reduction value be reduced by 50% or in
accordance with applicable regulations.
Explanation of attenuation tables
ANSI S3.19-1974
A:1
Frequency (Hz)
A:2
Mean attenuation (dB)
A:3
Standard deviation (dB)
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 23 decibels (dB).
3. The level of noise entering the ear is approximately equal
to 69 dB(A).

FITTING INSTRUCTIONS
Headband
E:1
Slide out the cups and tilt the top of the shell out, as the
cable must be on the outside of the headband.

while holding the headband in place.
E:3
The headband should be positioned across the top of the
head as shown and should support the weight of the headset.

.
E:6
Ventilation mode: To switch the unit from work mode
to ventilation mode, pull outward on the ear cups until you
hear a click

Avoid placing the cups against the hard hat as this
prevents ventilation.
OPERATING INSTRUCTIONS
CHARGING AND REPLACING THE BATTERIES
(fig. 1)
1. Detach the latch on the left cup with your fingers.
2. Open the cup.
3. Insert or replace the batteries. Make sure the polarity

to access the
configuration menu, see “Configuring your headset”.
CAUTION:
Use only 3M™ PELTOR™ USB charger
FR09
and 3M™ PELTOR™ USB wall adapter
FR08
with 3M™ PELTOR™
LR6NM
rechargeable batteries
(or equivalent AA Ni-MH rechargeable batteries.)
CAUTION:
The battery may not be charged if the
ambient temperature e113 °F (45 °C).
NOTE:
- Do not charge alkaline batteries as this may cause damage
to the headset.

®
streaming and level-dependent: approx 78 hours
NOTE:
Depending on the environment, temperature, and battery,
the operation time may vary.
