To activate the VPS, push the slider upwards (Fig. 7B) until you hear the click which
means the slider and VPS are correctly in place.
The VPS has been designed to ensure an easy, quick and tool-free disassembly.
Precautions for use
The current approval standards (ECE 22-05) state that the 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, when riding during the day under partic-
ularly bright weather conditions, e.g. very strong sunlight caused by high intensity
and/or incidence of the sunbeams, the use of sunglasses - which have a transmit-
tance much lower than 50% - turns out to be advisable, if not absolutely necessary,
to reduce eye fatigue on long trips. Sunglasses reduce the risk of direct dazzling as
opposed to the use of mere approved visors. However, the use of sunglasses makes
it difficult to perform in emergency situations 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 be used only during the day and under the environmental conditions
described before.
- At night and/or in conditions of scarce visibility, the VPS MUST be deactivated.
- Always check that the VPS is properly positioned according to the different
weather/environmental conditions and/or to the above mentioned recommenda-
tions 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 doesn't 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.
- Please refer to the proper section in the helmet user's manual for the VPS and
visor maintenance and cleaning operations.
- The VPS antifog/antiscratch treatment remarkably 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 visibil-
ity and/or sharpness of vision: In this case, deactivate the VPS.
- In case of rain, the direct contact of raindrops with the antifog/antiscratch-treat-
ed VPS quickly reduces sharpness of vision, thus causing scarce visibility: In this
case, deactivate the VPS.
- The special VPS antifog treatment is usually sensitive to high temperatures or
heat sources. In this case, contaminations caused by contact with other materi-
als 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), it is recommended to
make sure the visor is not touching other materials.
