4. Setup and Operation
4.1 Initial Fit and Adjustment
- Ensure the helmet fits snugly around your head without causing pressure points.

The integrated HJ-V12 sun visor can be deployed or retracted using the slider mechanism located on the side of the helmet. Adjust it to your preferred position for optimal sunlight reduction.
