4.3 To keep the features of the visor in good conditions over time, let the helmet dry
in a ventilated and dry place with the visor open after use. Keep it away from heat
sources and store it in a place away from direct light.
4.4 Do not use solvents or chemical products.
VISION PROTECTION SYSTEM (VPS)
The exclusive inner VISION PROTECTION SYSTEM (VPS) is a LEXAN™ (*) polycar-
bonate moulded sunscreen with scratch-resistant/fog-resistant treatment. It is very
simple and practical to use: just lower it to activate it or lift it to remove it from the field
of vision. It is useful in all sorts of situations, both on long journeys out of town and
shorter town trips.
Moreover, the innovative fastening system allows you to assemble and disassemble
the sunscreen without the need of any tools for ordinary maintenance and cleaning
operations.
1 VPS OPERATION
The VPS mechanism allows to activate the sunscreen by simply lowering it until it par-
tially covers the visor field of vision. In this way, the desired light transmittance reduc-
tion is achieved.
At any time, without operating the visor, the VPS can be deactivated with a simple
movement and easily lifted up to restore the normal conditions of visibility and protec-
tion guaranteed by the approved helmet visor.
1.1 To activate the VPS, move the slider as in Fig.8A until you hear a click
confirming that the VPS is in the desired position.
The VPS is adjustable in a range of intermediate positions to ensure the best
comfort for the user with respect to the terms of use.
1.2 To deactivate the VPS, move the slider as in Fig.8B.
2 PRECAUTIONS FOR USE OF VPS
The current approval standards (ECE22-05) state that the visor minimum light transmit-
tance levels must be greater than 80% when riding at night and not less than 50% when
riding during the day. For this reason, under particularly bright weather conditions, e.g.
very strong sunlight caused by high intensity and/or incidence of the sunbeams, the
use of sunglasses - which entail a transmittance much lower than 50% - turns out to
be advisable, if not absolutely necessary. This in order to reduce eye fatigue on long
trips. Sunglasses also reduce the risk of direct dazzling as opposed to the use of mere
approved helmet visors. However, the use of sunglasses makes it difficult to perform
emergency manoeuvres when the maximum visibility range of the helmet visor must be
quickly restored. Just think, for example, of what happens when you enter a tunnel or
when unexpected changes in environmental brightness occur. Thanks to its operating
mechanism, the VPS makes these operations much easier.
WARNING
- Use the special slider to activate/deactivate the VPS; do not deactivate the VPS
by handling it directly.
- The VPS can only be used during the day and under the environmental conditions
described before.
