MAINTENANCE
The outside of the muff and the sealing ring can easily be cleaned with soap and water. Ear muffs and in particular cushions
may deteriorate with use and ageing and should be inspected regularly for cracks and leakage. The cushions are filled with
foam and are replaceable. Worn or damaged parts are easily replaced (figure C). Use only hygiene kits from the manufacturer,
designed for electronics, order number 60085 Basic Line, 60084 Pro Line. The hygiene kit should be replaced at least twice a
year for standard use to ensure that the noise attenuation performances are maintained. This product may be adversely affected
by certain chemical substances. Further information should be sought from the manufacturer. The user must ensure that the
hearing protectors or hearing protector/helmet combination:
- fit properly and are adjusted and maintained in compliance with our instructions.
- is always used in noisy environments.
- is inspected regularly to ensure good condition.
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 ear muffs must not be immersed in water!
STORAGE
When the hearing protector is not in use, store it in such a way that the headband is not stretched and the cushions are not
compressed. Helmet mounted ear muffs must always be stored in the working position. Keep the ear muffs dry and clean, and
store them at normal room temperature. Do not place the hearing protector in direct sunlight. In the case of helmet mounted
hearing protection, lower the ear muffs and press them inwards (figure B7). If the product is to be stored for a longer period, it
is recommended that the batteries are removed from the battery holder to prevent them from damaging the product. If the
above recommendations are not followed, the protection afforded by the hearing protector may be severely impaired.
LIMITED TROUBLE SHOOTING
If the electronics cease to function 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.
Ensure that there is no moisture inside the muffs. If there is, remove the insert to allow the muffs to dry, e.g. overnight (figure
