THE FOLLOWING SUPPLEMENTARY INFORMATION APPLIES ONLY TO VERSIONS
75301, 75302, 75302-X, 75302-X LED, 76302 & 76302-X:
Connection
The product has one input, 3.5 mm, for connecting an external acoustic source, e.g.: communication radio,
hunting radio, mobile phone, etc. We recommend that you connect the angled jack plug to the hearing
protectors as this gives the most secure connection and is least interfering. Refer to the operating instructions
for the external audio equipment to ensure that it is correctly connected. The impedance of the product is 32
Ohms. The circuit must not be subjected to a signal greater than 5 volts to prevent permanent damage. If the
audio signal level does not exceed:
75301: 244 mVrms
75302, 75302-X, 75302-X LED, 76302 ja 76302-X: 926 mVrms
(rms =root mean square of signal strength), the sound pressure level inside the hearing protector will not
exceed 82 dB(A). Note! Please see Table 1.1, 1.2, 1.3 and 1.4 for more detailed information.
THE FOLLOWING SUPPLEMENTARY INFORMATION APPLIES ONLY TO VERSIONS 75302-X LED

MAINTENANCE

The outside of the muff and the cushion can easily be cleaned with soap and water. Earmuffs 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 or gel and are replaceable. Worn or damaged parts are easily replaced
(figure B). Use only hygiene kits from the manufacturer, designed for electronics, order number 60089-S or
60092-S. The hygiene kit should be replaced at least twice a year for standard use to ensure that the noise
attenuation performances are maintained. The fitting of hygiene covers to the cushions may affect the
acoustic performance of the hearing protectors.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 protector:
• fits properly and is adjusted and maintained in compliance with our instructions
• are worn at all the time 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 inserts are regularly removed to
allow the muffs to dry, e.g., overnight (figure B). When removing the cushion and insert 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 hearing protectors must not be immersed in water!
STORAGE
When the hearing protector is not in use, the headband or neckband should not be extended or the cushions
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, the attenuation values ability could deteriorate considerably.
