USER INFORMATION GUIDE (EZ-1B)
workplace may be impaired while during the entertainment facility. You should therefore be
specifically watchful of your surroundings when wearing this hearing protection.
This hearing protector contains batteries and electrical components that may cause ignition in
flammable or explosive atmospheres. Do not use in environments where sparks may cause a fire
or explosion. Misuse can result in injury or death.
The performance may deteriorate with battery usage. The battery life time varies depending on
the mode of use and volume output. For FM radio mode usage time is about 100h.
When calculating the effective attenuation of the hearing protector, consideration should be given
to the output signals of the radio restoration. The calculated total A-weighted sound pressure
level inside the cup should not exceed 85dB.
The output of the electrical audio circuit of this hearing protector may exceed the daily limit sound
level.
Dispose of the product and batteries in accordance with national legislation.
This earmuff 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 manufacturer for
advice.
User is forewarned that the Bluetooth communication system through the smartphone may not
be suitable for essential safety related communication.
