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.

APPROVALS
Hereby, 3M Svenska AB declares that the PPE type
headset is in compliance with Regulation (EU) 2016/425
or Community Directive 89/686/EEC and other appropriate
directives to fulfill the requirements for the CE marking.
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 cup. An example can be seen in the picture
below. 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 last pages
of this user instruction.
The product has been tested and approved in accordance
with EN 352-1:2002/EN 352-3:2002, EN 352-4/A1:2005,
EN 352-6:2002.
These PPE products are audited annually (if Category
III products) and type approved by Finnish Institute
of Occupational Health, Notified Body No. 0403,
Topeliuksenkatu 41 b, FI-00250 Helsinki, Finland.
This product contains electrical and electronic
components and must not be disposed of using
standard refuse collection. Please consult local
directives for disposal of electrical and electronic
equipment.
LABORATORY ATTENUATION
The attenuation rating SNR was obtained with the device
powered off.
Explanation of attenuation tables:
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 variation in fit, fitting skill, and motivation of the user.
Refer to your applicable regulations for guidance on how to
adjust label values and estimate attenuation. In addition, 3M
strongly recommends fit testing of hearing protectors.
A:1 Frequency (Hz)
A:2 Mean attenuation (dB)
A:3 Standard deviation (dB)
A:4 Assumed protection value, APV (dB)
A:5
H = Hearing protection estimation for high frequency sounds
(ƒ ≥ 2000 Hz).
M = Hearing protection estimation for medium frequency
sounds (500 Hz < ƒ < 2000 Hz).
L = Hearing protection estimation for low frequency sounds
(ƒ ≤ 500 Hz).
A:6 Criterion Level
H = Criterion level for high frequency noise
M = Criterion level for medium frequency noise
L = Criterion level for low frequency noise
A:6 Explanation of the table of electrical audio input level
(headsets only)
1. Model designation
2. External Input Mode: mode 1–3, 0 = product switched off
3. External Input Volume: N = Normal, H = High, 0 = product
switched off
4. Input signal level U (mV, RMS)
5. Mean sound pressure level dB(A)
6. Sound pressure standard deviation, (dB)
7. Input signal level for which the mean plus one standard
deviation equals 82 dB(A).
The failsafe mode, where input signals can also be heard in
off mode, is available only on *-50 models.
A:7 Explanation of the table of criterion levels
The criterion level is the sound pressure level in dB(A) of the
noise environment resulting in 85 dB(A) effective to the ear
while wearing the hearing protectors. Three different criterion
levels are defined related to the frequency content of the noise.
1. Model designation.
H = criterion level for high frequency noise
M = criterion level for medium frequency noise
L = criterion level for low frequency noise
Compatible Industrial Safety Hard Hats
These earmuffs should be fitted to, and used only with, the
industrial safety hard hats listed in Table C. These earmuffs
were tested in combination with the following industrial safety
hard hats, and may give different levels of protection if fitted
to different hard hats.
