Peltor ComTac XP MT17H682FB-1000 Bedienungsanleitung Seite 8

Note: If these recommendations are not followed, attenuation and other
functions can be impaired.
WARNING! The output signal from the active-volume circuit in this hearing
protector can exceed the external audio signal 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 35-400, EN 35-6 00 and applicable
parts of EN 352-1 2002. Certificate issued by FIOH (registration no. 0403),
Laajaniityntie , FI-060 Vantaa, Finland.

3. Standard deviation
(B:3) Noise levels
Relationship between A-weighted sound pressure level outside and inside the
shell.
. Sound level dB (A) inside the shell
. 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 music is measured at
max 8 dB (A) equivalent noise level according to the PPE directive.
. Hrs/day
. Average level/electric signal X = 50 mV

. Level inside the shell [dB(A)]
. Input signal
(B:6) Criterion levels
A criterion level is the amount of noise (measured as A-weighted sound
pressure) outside the hearing protector that gives 85 dB(A) inside. The noise
level depends on the type of noise. H is high-frequency dominated noise, M
is noise that is not dominated by any given frequency, and L is low-frequency
dominated noise.
USE (C)
(C:) Open the headband.
(C: ) Slide out the shells. Tilt the top of the shell out, as the wire must be
placed on the outside of the headband.
(C:3) Adjust the height of the shells by pulling the shell up or down while holding
the headband down.
(C:4) The headband should lie across the top of the head.
(C:5) Press the shells in before collapsing. Leave about 4 mm (/8") of the
headband wire visible.
(C:6) Collapse the headband. Check that the ear cushions are not creased
and that they lie flat against one another. NOTE: Make sure to disconnect the
microphone plug for audio input (A:9) before collapsing the headband!
Power On / Power Off
Press and hold the volume up (+) or volume down (–) button for  seconds.
