SUOMY MX SPEED PRO Manual Del Usuario página 23

The only function of the press stud fitted on the chin strap is to
avoid fluttering of the end part while riding. The fact the press stud
is fastened is no guarantee that the helmet has been positioned
and closed correctly: the correct fastening of the strap must be
verified exclusively through the operations described in the previous
paragraphs.
To release the retention system, unfasten the press stud and pull the
tongue to loosen the closure. Slide out the end part of the strap from
the «D Rings ».
Use the unlocking tongue only to remove the helmet! Never unlock
while riding. If the retention system does not work correctly, do not
use the helmet and contact Suomy authorized personnel only.
