correct operation before use. If distortion or failure is detected, the wearer
should refer to the manufacturers advice.
•
When interference increases or the volume becomes too weak, it is time to
replace the batteries. Never replace or install batteries with the unit switched
on. Ensure that the battery is positioned correctly before using. See the figure
in the CARE section.
•
Do not store with the batteries installed.
•
In extremely cold conditions, warm up the hearing protector before use.
Note: If these recommendations are not followed, attenuation and other func-
tions can be impaired.
WARNING!
The output of the level-dependent circuit of this hearing protection may exceed
the external sound level.
IMPORTANT! For the best protection, brush aside hair around the
ears so the ear cushions fit snugly against the head. Spectacle
frames should be as thin as possible and fit close to the head.
TECHNICAL DATA (B)
(B:1) Attenuation values, SNR
The attenuation values and noise levels for the hearing protector have been
tested and approved according to EN 352-4 2001, EN 352-6 2002 and applica-
ble parts of EN 352-1 2002. Certificate issued by INSPEC (Registered Number
0194), Upper Wingsbury Courtyard, Wingrave, Aylesbury, Buckinghamshire,
HP22 4LW, United Kingdom.
Explanation of the attenuation value table
1. Weight
2. Frequency
3. Average attenuation
4. Standard deviation
5. Expected attenuation
(B:2) Attenuation values, NRR
1. Frequency
2. Average attenuation
3. Standard deviation
(B:3) Noise levels
Relationship between A-weighted sound pressure level outside and inside the
shell.
1. Sound level dB (A) inside the shell
2. Sound level dB (A) outside the shell. Max input signal level in dB (A)
(B:4) Input signal level/usage time
Maximum permitted audio signal in relation to usage time.
To prevent harmful levels, the input signal must not exceed the stated values
(average speech signal level). The earphone level for long-term average value
of music and speech is measured at max 82 dB (A) equivalent noise level ac-
cording to the PPE directive.

2. Average level/electrical signal X=390,5 mV
(B:5) Sound exposure when using the auxilary input
1. Level under the ear-muff [dB(A)]
2. Input voltage [mVrms]
