Precautions For Use
The current approval standards (ECE22-05) state that the visor minimum light transmittance
levels must be greater than 80% when riding at night and not less than 50% when riding dur-
ing the day. For this reason, under particularly bright weather conditions, e.g. very strong sun-
light 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 environ-
mental brightness occur. Thanks to its operating mechanism, the VPS makes these opera-
tions much easier.
WARNING!
- Sunshield does not comply to AS1609.
- 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/envi-
ronmental conditions and/or to the above mentioned recommendations for use.
- We recommend using the VPS only and solely together with the approved standard 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 main-
tenance and cleaning operations.
- The VPS scratch-resistant and 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 and fog-resist-
ant 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 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 VPS is not touching other materials.
VPS DISASSEMBLY INSTRUCTIONS
To remove the VPS system from the helmet, open the chin guard and lower the VPS by push-
ing the side slider towards the back of the helmet (Fig. 9 B). Hold the right lateral part of the
VPS and lift the VPS to the outside of the helmet (Fig. 10). Repeat the same operation on the
left side of the helmet.
VPS ASSEMBLY INSTRUCTIONS
To fit the VPS system from the helmet, open the chin guard and make sure the side slider is
placed towards the back of the helmet (Fig. 9 B). Insert the VPS left end into the left side guide
until the grip pawl is hooked in shell housing (Fig. 11). Repeat the same steps on the right side.
