of vision. It is useful in all sorts of situations, both on long journeys out of town and
shorter town trips.
Moreover, the fastening system allows you to assemble and disassemble the sun-
screen for ordinary maintenance and cleaning, using no tools.
1 OPERATION
The VPS mechanism allows you to activate the sunscreen by simply lowering it until the
visor field of vision is partially covered. In this way, the light transmittance is reduced
as desired. 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
protection guaranteed by the approved helmet visor.
1.1 To activate the VPS, move the slider as in Fig.10A 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.10B.
2 PRECAUTIONS FOR USE
Current homologation standards (ECE22-06) establish that the minimum light transmit-
tance levels of visors should be no less than 80%; for homologated sunscreens, the
minimum transmittance level should be no less than 20%.
This regulation also provides for the simultaneous use of the visor and sunscreen, both
as standard.
WARNING
We recommend you to use the VPS only and solely together with the homologat-
-
ed standard visor, which has a transmittance value greater than 80%.
- The VPS does not replace the protection guaranteed by the visor.
- The VPS can only be activated during daytime and in weather and environmental
conditions with a particular light, for example, strong brightness caused by high
intensity and/or incidence of sunlight.
- At night and/or in conditions of poor visibility, the VPS should be deactivated.
- Should sunglasses and/or photochromic lenses be used, the VPS should be de-
activated.
- Always check that the VPS is properly placed according to the different weather/
environmental conditions and/or to the above mentioned recommendations for use.
- Use the special slider to activate/deactivate the VPS; do not deactivate the VPS
by handling it directly.
- Always check that the VPS is clean and that it is properly working in order to avoid
scratches and/or anomalous wear on it every time it is activated.
- As for VPS and visor maintenance and cleaning operations, please refer to the
appropriate section in the helmet user's manual.
- The VPS scratch-resistant/fog-resistant treatment highly reduces fogging. Howev-
er, protracted periods of adverse weather and/or environmental conditions might
cause fogging and/or formation of condensation on the VPS, which entails a re-
duction of visibility and/or sharpness of vision: in this case, deactivate the VPS.
