A comfortable hearing protector designed for the specific noise level in which it is used is the best guarantee that you will wear the hearing
protector 100% of the time, thereby ensuring protection from permanent hearing loss.
• Ex approval does not apply if technical changes are made in ex-approved products. Only accessories with the same type
designation as the original equipment may be used.
• For the best protection, brush aside hair around the ears so the sealing rings fit snugly against the head. Spectacle frames should be
as thin as possible and fit close to the head.
• For maximum noise compensation, the microphone must be placed about 3 mm from the lips.
• Clean the outside of the headset regularly with soap and warm water. Note: Do not immerse in fluids!
• Despite its quality, the headset can wear out over time. Inspect it regularly to ensure that there are no cracks or sound leakage,
which will reduce its function. If used continuously, check the sealing rings often.
• Do not store the headset in temperatures exc55°C, for example in a windscreen or window.
• Certain chemical substances may be harmful to this product. Contact the manufacturer for more information.
(F) INPUT SIGNAL/PERIOD OF USE
Warning: The sound level from the earphones in this hearing protector can lead to a daily exposure that exceeds the permitted levels. The audio
signal in the earphones must therefore be adapted to the usage time. To prevent harmful levels, the input signal should not exceed 323 mV. At
a higher input voltage, the usage time must be decreased according to diagram D:1 (x = 323 mV). An electrical input signal level of 323 mV
corresponds to 82 dB (A) equivalent sound level (average value plus one standard deviation of the measured sound level. See table D:2).
Note: The maximum output effect of the earphones must not be exceeded.
(E) ATTENUATION VALUES
The hearing protector is tested and approved according to the PPE directive 89/686/EEC and applicable parts of the European standard
EN352-1, EN352-3:2002 and EN352-6:2002. Attenuation values from the test report for certificate issued by the Finnish Institute of Occupa-
tional Health, Topeliuksenkatu 41, FI-00250 Helsinki, Finland, ID# 0403.
Explanation of the attenuation value table:
1) Frequency in Hz.
2) Average attenuation in dB.
3) Standard deviation in dB.
4) Average Protection Value.
Results obtained in accordance with AS/NZS 1270 are listed in Table (F). Hearing protector Class 5 tested to AS/NZS 1270:2002.
When selected, used and maintained as specified in AS/NZS 1269.3:2005, this protector may be used in noise up to 110 dB(A) assuming
an 85 dB(A) criterion. A lower criterion may require a higher protector class.
