• Taking good general care of the helmet reduces its obsolescence to a minimum, both from a use and a helmet component point of view.
• Regularly clean the filter surface with a soft cloth and a non-aggressive cleaning solution, for example one for cleaning glass (do not
pour the product directly onto the filter).
• Get into the habit of making sure that the solar cells and the sensors have not darkened or are not covered in dirt. If they have or if they
are, clean them with a soft paper tissue, if necessary slightly dampened with a preparation for cleaning glass (do not pour the product
directly onto the filter).
ASSEMBLY
