VPS operation
The VPS mechanism allows to activate the sunscreen by simply lowering it until it
partially covers the visor field of vision. In this way, the desired light transmittance
reduction is achieved. At any time, without operating the visor, the VPS can be deac-
tivated with a simple movement and easily lifted up to restore the normal conditions
of visibility and protection guaranteed by the approved helmet visor.
To deactivate the VPS, push the side slider completely downwards (Fig.7A).
To completely activate the VPS push the side slider completely upwards (Fig.7B).
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.
Precautions for use
The current approval standards (ECE22-05) state that the visor minimum light trans-
mittance 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 direct sunlight, the use of sunglasses - which have a transmittance much
lower than 50% - turns out to be advisable, if not absolutely necessary, 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 brightness occur.
Thanks to its operating mechanism, the VPS makes these operations much easier.
WARNING
- 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 weath-
er/environmental conditions and/or the above-mentioned recommendations for
use.
- We recommend using the VPS only and solely together with the approved stand-
ard 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. Pro-
tracted 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-re-
sistant 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 temperatures
or heat sources. In this case, contaminations caused by contact with other mate-
rials 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.
