VPS operation
The VPS mechanism allows you to activate the sunscreen by simply lowering it until
it partially covers the visor field of vision. 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. 11A).
To completely activate the VPS, push the side slider completely upwards (Fig. 11B).
The VPS can be adjusted to 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 particu-
larly 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 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
- 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 above.
- 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 solely together with the approved standard vi-
sor, 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.
