• 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 exceeding +55°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 hear-
ing 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 70 mV. At a higher
input voltage, the usage time must be decreased according
to diagram D: (x = 70 mV). An electrical input signal level
of 70 mV corresponds to 8 dB (A) equivalent sound level
(average value plus one standard deviation of the measured
sound level. See table D:).
Note: The maximum output effect of the earphones must
not be exceeded.
Sound level at 0.5 V/ kHz: 8 dBA
Max output, continuous: 0 mW
short-term: 00 mW
(G) ATTENUATION VALUES
The hearing protector telephone is tested and approved according
to PPE directive 89/686/EEC and applicable parts of the European
EN 352-1:1993 standard. Attenuation values from the test report
for certificate issued by the Department of Physics, Finnish Institute
