Checking The Face Shield And Sun Visor - SCHUBERTH M1 Pro Manual

E. BEFORE EVERY JOURNEY

3. CHECKING THE FACE SHIELD AND SUN VISOR

Before every journey, check that the mechanisms of the face shield and sun
visor are working properly and that the face shield and sun visor will provide
sufficiently clear visibility. Any dirt should be removed before riding.
Check the face shield and sun visor for physical damage and cracks. A badly
scratched face shield will considerably impair your vision and should be replaced
before setting off on a journey.
Caution:
Never use tinted face shield or sun visor in conditions of poor visibility,
when riding at night or in a tunnel.
Caution:
Stop riding if visibility is poor.
