ensure that the noise attenuation performances are maintained. This product may be adversely affect-
ed by certain chemical substances. Further information should be sought from the manufacturer.
The user must ensure that the hearing protector:
– fits properly and is adjusted and maintained in compliance with our instructions
– is used all the time in noisy environments
– is inspected regularly to ensure good condition.
If the above recommendations are not adhered to, the protection afforded by the earmuffs can be
severely impaired. Moisture may occur inside the hearing protector muffs if used for long periods. To
avoid long-term affects of moisture on the electronic components it is recommended that the acoustic
absorbent is regularly removed to allow the muffs to dry, eg, overnight (figure C). When removing the
sealing ring and absorbent take great care not to touch the electronics board or cables. Changes in
position of cables could cause disturbance in the system. Do not subject the hearing protector to
rough handling, which can damage the electronics.
The earmuffs must not be immersed in water!
STORAGE
When the hearing protector is not in use, the headband should not be extended or the sealing rings
compressed. Keep the muffs dry and clean and keep them in normal room temperature. Do not allow
the hearing protector to lie in direct sunlight. If the product is to be stored for a longer period it is
recommended that the batteries be removed from the battery holder to prevent damage.
If the above recommendations for the hearing protectors are not adhered to the attenuation values
ability could deteriorate considerably.
LIMITED TROUBLE SHOOTING/CARE ADVICE
If the electronics cease to function it may be easy to rectify the problem. Please check the following:
• Replace the batteries with new ones.
• Ensure that the batteries are correctly fitted in the hearing protector.
• Ensure that the battery plates make good contact with the batteries.
• Ensure that the battery plates have not become coated with verdigris.
• When the hearing protector is worn for long periods, moisture may build up inside the earmuffs.
To prevent long-term effects of moisture on the electronic components we recommend that the inserts
are removed regularly to allow the inside of the earmuffs to dry out, overnight for example.
If these measures do not help, consult the point of sale.
WARNING!
• These earmuffs reproduce ambient sound electronically. The user must check the function before
using the product. If distortion or other fault is detected, follow the instructions for changing and
maintenance of the batteries. If this does not help, consult an authorized agent.
• The function can deteriorate in step with discharging of the battery. In normal use, the estimated life
of the batteries is about 150 hours (Basic Line) and 600 hours (Pro Line).
• The estimated A-weighed sound level inside the muff, with consideration taken to attenuation val-
ues (table, fig. K), shall not exceed 82 dB(A).
• Remember that hearing protectors generally can shut out ambient sound, such as warning shouts,
alarms and other important signals. Be therefore extra cautious of your surroundings when wearing
hearing protectors.
• The integrated microphones for reproduction of ambient sound increase safety considerably in your
daily work. NOTE. It is possible to disconnect the level dependent function, which means that warn-
ing signals and warning shouts would be much more difficult to hear. To minimize the risk of acci-
dents we therefore recommend that the level dependent function be connected as far as possible.
• The output signal from the level dependent function can exeed the actual external sound level.
• The level dependent function may deteriorate in rain or moist conditions and the user should there-
fore be aware of the possible deterioration. If deterioration occurs, immediately allow the micro-
phones in the hearing protector to dry (with open muffs for 24 h) until the function is fully restored.
• The product and the batteries are to be disposed of in conformance with national regulations.
