FUNCTION
The IMPACT Sport amplifies surrounding
®
sounds such as voices, machines and
warning signals to safe levels yet it
provides good hearing protection. Loud
impulse sounds are effectively blocked
out and limited to safe levels. The unique
stereo microphones (3) allow detection
of the direction of ambient sounds,
enhancing communication abilities and
awareness of surroundings. This earmuff is
provided with electrical audio input.
INSTRUCTIONS FOR USE
Open the battery lid (1) by pushing the lid
up with your thumbs. Let it slide off of the
ear cup. Insert the two enclosed 1.5 V AAA
batteries. Make sure that the + and - poles
are in the correct position. Ensure that the
battery lid is closed completely.
1. Extend the headband before use.
2. Place the earcups over the ears with the
microphones (3) in the forward position
to obtain the best listening conditions
(picture A).
3. Adjust the earmuff fit position by sliding
the ear cups up or down on the side of
the headband (picture B).
4. The ear cushions should seal firmly
against the head (picture C). For
best results, remove all hair under
the cushion. Noise reduction will be
adversely effected by anything that
impairs the seal of the earmuff cushions
against the head, such as thick
spectacle frames, balaclavas, etc.
5. Turn on the volume control (2) and
adjust to a pleasant listening level.
6. After automatic power-off (4 hours),
turn the volume control off, wait 5
seconds, turn it on again to get another
4 hours of working time.

IMPORTANT USER INSTRUCTIONS
1. The earmuffs should be fitted, adjusted and
maintained in accordance with the instructions.
2. The earmuffs should be worn at all times in noisy
surroundings.
3. The earmuffs should be regularly inspected for
serviceability.
4. The earmuffs should be cleaned and disinfected with soap
and warm water. They must not be dipped into water.
5. Earmuffs and in particular cushions may deteriorate
with use and should be examined at frequent intervals
for signs of wear, for example, cracking or sound
leakage. Replacement cushions are available. For
cushion replacement, just pull off the old ones and
snap-in the new ones. To order new ear cushions please
see information about the hygiene kit.
6. The fitting of hygiene covers to the cushions may
affect the acoustic performance of the earmuffs.
7. Before and after usage, store in a dry place. The
temperature should not exceed +55°C (130°F).
8. The product may be adversely affected by certain
chemical substances. Further information should be
sought from the manufacturer.
9. The earmuff is provided with electronic restoration
of surrounding sound. The wearer should check
for correct operation before use. If distortion or
failure is detected, the wearer should refer to
the manufacturer's advice for maintenance and
replacement of the batteries.
10. Warning – performance may deteriorate with battery
usage. The typical period of continuous use that can
be expected is 350 hours.
11. The output signal of the sound restoration circuit of
this hearing protector does not exceed the values
known to constitute a risk to hearing.
12. Warning—for lower external levels, the sound level
under the earmuff can exceed the external level
(amplification). See "Sound restoration characteristics"
graph next page.
13. For the estimation of the effective attenuation of this
earmuff, the additional noise emission by the sound
amplification should be taken into account. The
estimated A-weighed noise level under the earmuff in
passive mode should not be greater than 82 dB(A).
14. The microphone's wind protector, which eliminates
wind noise etc., should be kept clean and changed
when necessary.
15. This earmuff is provided with an electrical audio input
jack. The wearer should check for correct operation
before use. If distortion or failure is detected, the
wearer should refer to the manufacturer's advice.
16. If the above mentioned recommendations are not
followed, the protection and function afforded by the
earmuffs may be severely impaired.
