C. THE HELMET
Note:
To avoid scratching the visor, never remove or fit the anti-fog lens unless
the visor unit is clean and dry.
When fitting the anti-fog lens, check that neither dust nor moisture are
able to get between the two surfaces.
When removing or fitting the anti-fog lens, it is always best to lay the visor
unit on a clean, dry cloth.
Note:
In view of the strong air pressure acting when travelling with an open visor,
we recommend riding with a closed visor at all times to prevent any dirt or
moisture from getting inside the helmet.
Note:
Never press the locking pins out with your fingers as they may break.
Caution:
As a result of the double lens structure, there is a possibility of greater
light reflection in the face schield, especially when riding at night. As a
rule, such light reflection is regarded as uncritical due to the absence of
fog with this type of visor. However, if this light reflection should cause
you difficulties – because of particular sensitivity to it, for example – you
should refrain from using the anti-fog lens.
Caution:
If moisture is present in or has penetrated the airtight area between the
two plates, you should remove the anti-fog lens immediately in order to
prevent any interference with visibility. Do not re-fit it until both plates are
completely dry (we recommend air-drying). If you should subsequently
detect any further penetration of moisture, the anti-fog lens should not be
used on any account and must be replaced.
Safety note
Check before each journey that the visor and sun visor mechanism are
functioning correctly and that the visor and sun visor will provide good visibility.
Any dirt should be removed before setting off. Check the visor and sun visor for
physical damage and cracks. Severely scratched or scuffed visors will seriously
impair visibility and should be replaced before setting off on a journey.
