Nolan N43 AIR Sécurité Et Instructions D'utilisation page 21

Keep it away from heat sources and store it in a dark place.
Do not use solvents or chemical products.
USE CONFIGURATIONS Fig. 23
Using the helmet in its full configuration (chin guard attached and visor closed)
obviously guarantees the best protection when compared to the other configurations.
• VENTILATION SYSTEM Fig. 24
The exclusive ventilation system, complete and extremely effective, makes the best
use of three different air flows: one front air intake, two upper ones and two rear air
extractors. These ensure optimum air circulation inside the helmet.
A Completely closed system (Closed front air intake and closed upper air intakes).
B Completely open system (Open front air intake and open upper air intakes).
