Nolan N40 Full Sécurité Et Instructions D'utilisation page 22

The VPS is adjustable in a range of intermediate positions to ensure the best com-
fort for the user with respect to the terms of use.
Precautions for Use
The current approval standards (ECE22-05) state that the visor minimum light tran-
smittance levels must be greater than 80% when riding at night and not less than
50% when riding during the day. For this reason, when riding during the day under
particularly bright weather conditions, e.g. very strong sunlight caused by high inten-
sity and/or incidence of the sunbeams, the use of sunglasses - which have a tran-
smittance much lower than 50% - turns out to be advisable, if not absolutely neces-
sary, to reduce eye fatigue on long trips. Sunglasses also reduce the risk of direct
dazzling as opposed to the use of mere approved helmet visor. However, the use of
sunglasses makes it difficult to perform emergency manoeuvres when the maximum
visibility range of the visor must be quickly restored. Just think, for example, of what
happens when you enter a tunnel or when unexpected changes in environmental bri-
ghtness 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 condi-
tions described before.
- At night and/or in conditions of poor visibility, the VPS must be deactivated.
- Always check that the VPS is properly positioned according to different wea-
ther/environmental conditions and/or the above-mentioned recommendations
for use.
- We recommend using the VPS only and solely together with the approved stan-
dard visor, which has a transmittance value greater than 80%.
- The VPS does not replace the protection guaranteed by the visor.
- Always make sure that the VPS is clean and that it is operating properly 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.
Protracted periods of adverse weather and/or environmental conditions might
cause fogging and/or formation of condensation on the VPS, which entails a
reduction of visibility and/or sharpness of vision: in this case, deactivate the
VPS.
- In case of rain, the direct contact of raindrops with the scratch-resistant/fog-
resistant treated VPS quickly reduces sharpness of vision, thus causing scarce
visibility: in this case, deactivate the VPS.
- The special VPS fog-resistant treatment is usually sensitive to high temperatu-
res or heat sources. In this case, contaminations caused by contact with other
materials might occur. These contaminations will cause marks and stains to
develop. In these cases (e.g. when the helmet is kept in the top case on hot
days), it is recommended to make sure the visor is not touching other materials.
