Warning!

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 a 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.

• or some individuals, excessive sound pressure from earphones and headphones may cause hearing loss.

• 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.

• 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 spectacle 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. When damp, turn the shells outwards and remove the cushions so they can dry. Remove the batteries. The hearing protector must be stored in a dry and clean environment out of direct sun light, e.g. in its original packaging.

• This hearing protector is provided with level-dependent attenuation. The wearer should check correct operation before use. If distortion or failure is deteced, the wearer should refer to the manufacturers advice for maintenance and replacement of the battery.

• Warning! Performance may deteriote with battery usage. The typical period of continuous use that can be expected from the hearing protector is 120/130/1000 hours.

• Warning! The output of the level-dependent circuit of this hearing protector may exceed the external sound level. Fitting & adjustment (A)
  Brush away all hair from the ears and place the hearing protectors over the ears so that they fit comfortably and snugly. Ensure that the ears are completely enclosed by the hearing protectors and that you have even pressure around the ears.

• Headband (A1)

• Helmet/Cap mount (A2)
  Push the hearing protectors helmet attachment into the helmet slot until it locks into position. Place the hearing protectors over the ears and press inwards until you hear a click. Adjust the hearing protector and helmet so that they fit comfortably on your head.
