WARNING!
This hearing protector is intended to protect the wearer from hazardous noise levels when fitted in accordance with this user
instruction. Any other use is not intended and therefore not permitted. It is important that the instructions for use are followed.
Failure to do so could result in a drastic decrease of the noise attenuation and may lead to serious injury.
Read these user instructions carefully!
•The hearing protector must be worn at all times in noisy environments to provide full protection! Only 100% wear time provides
full protection.
•Do not remove the headset to change settings in a noisy environment. Use menu system with guide voice while wearing the
headset.
•The audibility of warning signals at a specific workplace may be impaired due to over-protection, when using a hearing
protector with too high a noise attenuation performance in relation to the noise environment.
•When using hearing protection with entertainment audio features, remember to adjust the volume when working in noisy
environments so that any warning signals etc. can be heard.
•In some individuals, excessive sound pressure from earphones and headphones may cause hearing loss.
•This hearing protector features the level-limiting of audio signals from the speakers to a maximum of 82 dB(A) at the ear.
•Do not use this product in a potentially explosive atmosphere.
•This product may be adversely affected by certain chemical substances. Further information should be sought from the
manufacturer.
•The earmuff is provided with safety related audio input. The user should check correct operation before use. If distortion or
failure is detected the user should refer to the manufacturers advice for maintenance.
•The hearing protector's noise attenuating properties can dramatically decrease when used with, for example, thick eyeglass
frames, ski masks/balaclavas, etc.
•Use of perspiration/hygienic protection over the sealing rings can reduce the hearing protector's noise attenuation properties.
•Earmuffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for cracking and
leakage.
•Immediately discard the product if it shows any signs of cracking or damage.
•Hygiene kit should be changed at least twice a year. Make sure you choose the correct hygiene kit for your hearing protector.
•Clean the product with mild soap. You must be sure that the detergent you use does not irritate the skin. Do not dip the product
in water.
•The hearing protector must be stored in a dry, clean environment out of direct sunlight, e.g. in its original packaging.
•Ensure battery condition and state of charge to ensure capacity is sufficient throughout a critical task. Battery capacity may
deteriorate over time.
•Ensure matching configuration by testing communication before commencing critical task
•Note, on communication radio, only one unit can transmit at the same time. A unit can not receive a message while
transmitting.
•Ensure that the used radio frequencies are license-free or obtain a license in the region you operate.
FITTING & ADJUSTMENT
Brush away all hair from your ears and place the earmuffs over your ears so they fit comfortably and snugly. Ensure your ears
are completely enclosed by the earmuffs and that you have an even pressure around your ears.
Headband (pic. C1)
Adjust the headband size so that it rests lightly against the crown of your head.
Helmet mount (pic. C2, C3)
Push the hearing protectors' helmet attachment into the helmet slot until it locks into position. Place the hearing protectors over
your ears and press inwards until you hear a click. Adjust the hearing protectors and helmet so they fit comfortably.
Boom microphone (pic. C4)
The boom microphone (A:6) should be placed approximately 1 cm from the mouth for best noise suppression and clear speech
intelligibility. Make sure the microphone is facing the mouth, with the TALK text imprint towards the mouth. Attach the Windshield
(B:3) for use in windy environments.
