Nolan N21 VISOR Sécurité Et Instructions D'utilisation page 6

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 during the day. For this reason, under particularly bright
weather conditions, e.g. very strong sunlight caused by high intensity and/or incidence of the sunbeams, the use of sun-
glasses - 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 environmental brightness occur. Thanks to its operating mechanism,
the VPS makes these operations 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 poor visibility conditions, 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 recommendations for use.
- We recommend using the VPS only and solely together with the approved standard visor, which has a transmittan-
ce 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 anoma-
lous 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.
5. VPS Disassembly
To remove the sunscreen from the helmet, open the visor completely and lower the VPS by pushing the slider complete-
ly upwards (Fig. 7 B).
Hold the left lateral part of the sun screen and pull it toward the outside of the helmet (Fig. 8). Repeat the same opera-
tion on the right side of the helmet.
6. VPS Assembly
To remove the sunscreen, open the visor completely and push the slider completely upwards (Fig. 7 B).
Insert the sun screen left end into the left side guide until the grip pawl is hooked in shell housing (Fig. 8).Repeat the same
operation on the right side of the helmet.
