C. THE HELMET
Aeroacoustically uncritical zone
NOISE-REDUCTION-SYSTEM (N.R.S)
The innovative noise-reduction system allows the noise level in
the helmet to be varied, thus enabling sounds to be experienced
at different intensities. Two settings are available.
Race (N.R.S open): In this setting, acoustic
signals are perceived with a heightened
intensity. Recommended for race
conditions.
Street (N.R.S closed): In this setting, the
acoustics in the helmet are reduced to the
perception of important traffi c and warning
signals. Recommended for longer journeys.

9. WIND DEFLECTOR
By fi tting the wind defl ector supplied, undesired entry of wind
from the airstream can be prevented. The device also further
reduces the noise level in the helmet.
To fi t, slide the retaining pocket of the
wind defl ector gradually outwards from
the centre into the guide gap between the
interior of the helmet and the outer shell.
Tip: The fi t of the underside of the helmet is very important
for further reducing the noise level in the helmet. Take care
to ensure that the helmet is properly closed. For smaller neck
sizes we recommend that you wear a scarf.
