5. IMPORTANT USER INFORMATION

The headset must be fitted, adjusted and maintained in accordance with the instructions given in this manual.
The headset must be worn at all times in noisy surroundings and be inspected regularly for serviceability.
NOTICE! 100% use of a proper hearing protector is the only certain protection from hearing loss.
In environments with more than 82 dB A-weighted noise level, you need to protect your hearing. The hearing receptors in
your inner-ears may be irreparably damaged if you lift a cup of your hearing protectors for even a very short time in a noisy
environment.
The use of a comfortable hearing protector, designed for the specific noise level in which it is used, is the best guarantee to
that you will wear the hearing protector 100% of the time to protect yourself from permanent hearing loss.
For best protection, brush aside excess hair around your ears so the cushions fit snugly on your head. The arms/bands of any
spectacles or goggles worn should be as thin as possible to allow the hearing protector to fit closely to the head.
This hearing protector provides an entertainment audio facility. The the entertainment audio signal is limited to 82 dB(A)
effective to the ear for a maximum input signal level over the Bluetooth protocol.
Warning! The audibility of warning signals may be impaired while using the entertainment facility. This ear-muff is provided
with electrical audio input. The wearer should check correct operation before use. If distortion or failure is detected, the wearer
should refer to the manufacturers advice.
IMPORTANT! For the best protection, brush aside hair around the ears so the ear cushions fit snugly against the head.
Spectacle frames should be as thin as possible and fit close to the head to minimise acoustic leakage.
