FITTING INSTRUCTIONS
A.
The IMPAC P Sport amplifies surrounding sounds such as voices , machines and warning signals to safe levels yet it prov i des
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 , enhanc i ng 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 pos i tion to obtain the best listening conditions
(picture A) .
3. Adjust the earmuff fit position by sl idi ng 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 part i cular 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 hyg i ene 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 restorat i on 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 no i se em i ssion by the sound
amplification should be taken into account. The estimated A-weighed noise lev el under the earmuff in passive mode should
not be greater than 82 dB(A) .
The microphone 's wind protector, which elim i nates wind noise etc ., should be kept clean .
Th is earmuff is provided with an electrical audio input jack . The wearer should check for c orrect operat i on before use . If
distortion or failure is dete c ted , the w earer 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 impai r ed .
AUDIO INPUT LEVELS: The audio level in the earphones is dependent on the audio input level . To prevent harmful noi se
le vels in the earphones never exceed the values and us age 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 wi th _ your thumbs . Le t ii
s lide off of the ear cup . Remove the old batteries. Insert two new 1.5V 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 _ age . Chan _ ge

The level of noise e ntering a person 's ear, when hearing protection is worn as directed , is closely appro x imated by the
di fference between the A- weighted environmental level and the NRR .
Example : /. The env i ronmental 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 no i se . 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 .
