APPROVALS

Hereby, 3M Svenska AB declares that the Bluetooth
communication is in compliance with Directive 2014/53/EU and
CE marking. 3M Svenska AB also declares that the PPE type
headset is in compliance with Regulation (EU) 2016/425 or
Community Directive 89/686/EEC.
The applicable legislation can be determined by reviewing the
Declaration of Conformity (DoC) at www.3M.com/peltor/doc.
The DoC will also show if some other type-approvals are also
applicable. When retrieving your DoC, please locate your part
number. The part number of your earmuffs can be found at
the bottom of one of the cups. An example can be seen in the
picture below.
The PPE is audited annually (if Category III products) and
type approved by the Finnish Institute of Occupational Health,
Helsinki, Finland. The product has been tested and approved
in accordance with EN 352-1:2002/EN 352-3:2002, EN 352-
4:2001/A1:2005, EN 352-6:2002, EN 352-8:2008.
A copy of the DoC and additional information required in
the Directives can also be obtained by contacting 3M in the
country of purchase. For contact information, see the last
pages of this user instruction.

LABORATORY ATTENUATION

The attenuation rating (SNR/NRR) was obtained with the
device powered off. Explanation of attenuation tables:
A. European Standard EN 352
Research suggests that users may receive less noise reduction
than indicated by the attenuation value(s) on the packaging, due
to your applicable regulations for guidance on how to adjust
label values and estimate attenuation. In addition, 3M strongly

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 25 decibels (dB).
3. The level of noise entering the ear is approximately equal to
67 dB(A).
CAUTION: For noise environments dominated by frequencies
below 500 Hz the C-weighted environmental noise level should
be used.

were tested in combination with the following industrial safety
different hard hats.
