Always put on the ear defenders before exposing yourself

allow them to expand to their normal size.
4. Extend the headband and place the cups over your ears.
5. Adjust the headband so that it rests on the top of your head.
6. Adjust the cups until they feel comfortable and are a snug fit.
Important:
• The ear defenders can deteriorate over time and can even
be damaged by certain chemicals etc.
• Check your ear defenders regularly. The cushions should be
intact, the cups free from cracks and the headband should
be flexible.
• Always put on the ear defenders before exposing yourself to
noise and wear them at all times.
• The ear defenders are of normal size range according to
EN352-1, designed to fit the majority of wearers.
• Wash the ear defenders with soapy water; do not use
strong detergents or alcohol etc.
• Store the ear defenders in a clean, dry and cool place when
not in use.
• The ear defenders should be fitted, adjusted and maintained
according to the information from the manufacturer.
• Failure to follow the recommendations will seriously impair
the protective effect of the ear defenders.
• The cushions and liners are not replaceable and therefore
there are no replacement cushions for sale.

If these directions are not followed, the noise
reduction capability can be impaired.
