USER’S INSTRUCTIONS

PRO-LINE: ACTIVATING THE HEARING PROTECTOR/BATTERY INSTALLATION/REPLACEMENT (figure C) The hearing protector requires two standard alkaline 1.5V AAA/LR03 batteries. Rechargeable batteries, for example, NiMH 1.2 V or NiCd 1.2 V, should not be used as they may significantly reduce the operating time of the product. The batteries are protected from moisture and dirt by our unique battery compartment. You can easily install and replace batteries by following the instructions (figure C): Unscrew the battery cover. Insert the first battery with the (–) pole facing inwards. Shake the earmuff lightly so that the battery falls into place inside the earmuff. Then insert the second battery with the (+) pole facing inwards. Refit the battery cover. Note! Always switch off the product before replacing batteries. Make sure that the battery’s polarities are inserted correctly and secure that the battery lid is completely tightened.

FUNCTION KEYS (figure D)

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.

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.

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. If these measures do not help, consult the point of sale.

THE FOLLOWING SUPPLEMENTARY INFORMATION APPLIES TO SUPREME, ONLY IN USA/CAN:

Tested according to ANSI Specifications, ANSI S3.19-1974 Information required by E.P.A: The level of noise entering a person’s ear, when hearing protection is worn as directed, is closely approximated by the difference between the A-weighted environmental level and the NRR. Example: The environmental noise level at the ear is 92 dB(A). The NRR is 23 decibels (dB). The level of noise entering the ear is approximately equal to 69dB(A).

CAUTION:
For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing protection can be recommended for protection against the harmful effect of impulse noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise, such as gunfire.
