FITTING INSTRUCTIONS
A.
The IMPACP 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 A). 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, hats, 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:
The earmuffs should be fitted, adjusted and maintained in accordance with the instructions.
The earmuffs should be worn at all times in noisy surroundings.
The earmuffs should be regularly inspected for serviceability.
The earmuffs may be cleaned with mild soap and water. They must not be dipped into water.
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.
The fitting of hygiene covers to the cushions may affect the acoustic pertormance of the earmuffs.
Before and atter usage, store in a dry place. The temperature should not exceed 130' F (+55' C).
The product may be adversely affected by certain chemical substances. Further information should be sought from the
manufacturer.
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.
The output signal of the sound restoration circuit of this hearing protector does not exceed the values known to constitute
a risk to hearing. 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).
The microphone's wind protector, which eliminates wind noise etc., should be kept clean.
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.
If the above mentioned recommendations are not followed, the protection and function afforded by the earmuffs may be
severely impaired.
AUDIO INPUT LEVELS: The audio level in the earphones is dependent on the audio input level. To prevent harmful noise
levels in the earphones never exceed the values and usage described in figure A:1. Mean/average level of electrical input.
Maximum permitted audio input level for 8 hours of usage time, compressed speech and music U; 138 mV. See FigureA-1.
BATTERY REPLACEMENT: Open the battery lid (1) by pushing the lid up with_ your thumbs. Let ii
slide off of the ear cup. Remove the old batteries. Insert two new 1.5 V AAA-alkaline batteries mto the
battery compartment (1 ) in accordance with the instructions inside the compartment. Ensure that the
battery lid is closed completely. Warning - pertormance may deteriorate wrth battery us_ a ge. Chan_ ge

The level of noise entering a person 's ear, when hearing protection is worn as directed, is closely approximated by the
difference between the A-weighted environmental level and the NRR.
Example: /. The environmental noise level at the ear is 92 dB (A).
2. The NRR is 22 decibels (dB).
3. The level of noise entering the ear is approximately equal to 70 dB (A).
/,\ WARNING: For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise
L.D.
level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing
protectors can be recommended for protection against the harmful effects of impulse noise, the Noise Reduction Rating
(NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable
against Impulse noise, such as gunfire.
NOTE: The Noise Reduction Rating is derived from testing procedures at an independent laboratory and in accordance to
acceptable A.N.S.I. standards. Actual noise reduction can vary from laboratory results as labeled. Protection is maximized
when: proper protector is selected for application, a good training program is utilized and proper fitting techniques are followed .
