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.
This ear-muff is provided with level-dependent attenuation.
The wearer should check correct operation before use. If distortion or failure is detected, please refer to the instructions for
replacement of the battery.
Warning! - Performance may deteriorate with battery usage.
Warning! - The output of the level-dependent circuit of this hearing protector may exceed the external sound level.
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.
Warning! The output of the electrical audio circuit of this hearing protector may exceed the daily limit sound level.
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.
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.
Warning! If the recommendations given in this manual are not adhered to, the protection afforded by the headset will be
severely impaired.
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.
6. TECHNICAL DATA
6:1 Attenuation values, SNR (F)
The attenuation values and noise levels for the headset are tested and approved according to EN 352-1:2002, EN 352-3: 2002,
EN 352-4: 2001/A1:2005, EN 352-6 : 2002. Testing performed and Certificate issued by Combitech AB, Box 168, SE-73223
Arboga, Sweden, ID#2279 .
Explanation of the attenuation data tables:
1. Weight
2. Frequency (Hz)
3. Mean attenuation (dB)
4. Standard deviation (dB)
5. Assumed Protective Value (dB)
6:2 Sound exposure when using the Flex jacket (G)
The earphone level for music is measured at:
Max AUX input signal level = 1,5 V rms
Table (G) gives the Sound pressure values corresponding to the input signal level applied on the Flex jacket (B:6).
G:2 gives the Mean sound pressure value (dBA), and G:3 gives the Sound Pressure Standard Deviation (dBA) at a specified
input signal Voltage level (G:1) (mV, RMS).
AUX input signal level: 32 mV rms = 82dB
