HEADSET AND NOISE ATTENUATING HEARING PROTECTOR
This hearing protector allows communication and music streaming via Bluetooth®. The headset features wireless
communication and music streaming via units that are compatible with Bluetooth® and A2DP.
Warning!
This hearing protector is intended to protect the wearer from hazardous noise levels when fitted in accordance with this user
instruction. Any other uses are not intended and therefore not allowed. It is important that the instructions for use are followed.
Failure to do so could result in a drastic reduction in the noise attenuation and may lead to serious injury.
Carefully read these user instructions!
• The hearing protector must be used at all times in noisy environments to provide full protection effect! Only 100% wear time
provides full protection.
• The audibility of warning signals at a specific workplace may be impaired if over protected, when using a hearing protector with
too high 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.
• For some individuals, excessive sound pressure from earphones and headphones may cause hearing loss.
• This hearing protector features level-limiting of audio signals from the speakers to maximum 82 dB(A) at the ear.
• Do not use this product in a potentially explosive atmosphere.
• It is recommended that any machinery is switched off, and/or that you walk away from the noisy area when answering a phone
call from the headset.
• Certain chemical substances can have a destructive effect on this product. More information is available from the
manufacturer.
• Ensure that the hearing protectors are regularly inspected for serviceability.
• The hearing protector's noise attenuating properties can dramatically decrease with usage of 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 showing signs of cracks or damage.
• Hygiene kit should be changed at least twice per 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 and clean environment out of direct sun light, e.g. in its original packaging
