FITTING INSTRUCTIONS EAR MUFFS
HEADBAND VERSION (fig B)
Place the cups over your ears and adjust the headband and cups to a comfortable position. Make certain that the cushions seal tightly around the ears. The pressure of the band against the head can be
adjusted with our unique adjustment button (fig. B1).The headband is intended to be worn straight over
the top of the head. Make sure that the headband is not stored in a stretched position and that the
cushions are not compressed when the hearing protector is not in use. Keep the cups clean and dry and
store them at normal room temperature. Keep out of direct sunlight.
HELMET MOUNTED VERSION (fig H)
FITTING THE CUPS (figs. H1–H2)
Pull the cup down to the lower position and lift it outwards (fig. H1). Press the cup attachments into the
slots on the sides of the helmet (fig. H2). Detach the harness from the rear of the helmet, place the wires
leading from the cups above the harness’ attachment and reattach the harness. Make sure that the wires
are free.
WORKING POSITION (fig. H3)
Adjust the cups to a comfortable position. Make sure that the cushions seal tightly around the ears.
STAND-BY POSITION (fig. H4)
Lift the cups from the ears to the fixed stand-by position. In noisy environments, always wear the hearing protector in working position.
TRANSPORT POSITION (fig. H5)
First lift the cups into stand-by position. Then rotate them up to the next fixed position. In this position,
the cushions cannot be damaged or dirtied and the cups can dry internally.
STORAGE (fig. H6)
When the helmet is not in use, lower the cups and press them inwards. Keep the cups clean and dry
and store them at normal room temperature. Keep out of direct sunlight.

THE NOISE-CANCELLING BOOM MICROPHONE (fig. C)
The ear muffs are equipped with a noise-cancelling speech microphone that is specially designed to
work in noisy environments. The product is supplied with an electret microphone or dynamic microphone, depending on the intended application.
Adjust the boom microphone so that the microphone is level with your mouth and about 3–5 mm from
your lips (diagram C). It is important not to exceed this distance when working in a noisy environment,
in order to get the best performance from the noise-cancelling microphone. We recommend that you
keep the microphone in this position whether you are talking or not. A wind protector should be used
to prevent interference from wind noise.
CABLE AND CONTACT
The hearing protector is equipped with cable and adapter for connection to external communication
