WARNINGS

This headset will only provide the hearing protection as indicated by the SLC80
rating when it is maintained in good working order and fitted correctly. Other
factors affecting the noise attenuation characteristics of the headset are items
which affect the seal between the Ear Cushion and the head e.g. thick framed
glasses, protective clothing such as balaclavas, thick beards, etc.

It is vitally important that you give consideration to the sound output produced
by the earphones in the headset itself. You must ensure that the volume setting
of the radio, or other connected device, is adjusted to a safe listening level as
there are no output limiting devices included within the electronic circuitry of the
headset.

For correct care of this Headset, you must refer to the Care and Maintenance
Instructions on page 7.

adjusted slightly forward or rearwards for maximum comfort. See figure D below.
