retention system
With the micrometric adjustment
retention system, the strap must
be adjusted before being fas-
tened.
Following the indications of the
figure below, adjust the length of
the strap, lengthening or shorten-
ing the portion of tape that passes
through the metal ring (1) until the
helmet fits snugly when the strap
is fastened.
To fasten the helmet, slot the ser-
rated tab into the metal buckle (2)
3
and push it as far as possible (3)
until the strap presses against the
jaw. The micrometric adjustment
system enable further, more pre-
cise "calibration" of comfort and
fit thanks to the possibility to use
the preferred number of positions
on the serrated tab (It is best to
insert the tab as far as possible
into the buckle).
Check that the helmet fits snug-
ly (see the paragraph entitled
"Choosing the right helmet" in the
"Safety Warning" booklet).

lever using the ribbon (4) and then
open the buckle (5) as shown in
figure below.
N.B. BUTTONS/VELCRO POSI-
TIONED ON THE RETENTION
SYSTEM ARE NOT FASTEN-
INGS BUT ARE ONLY TO PRE-
VENT FLAPPING: THEY MUST
NOT BE USED AS AN ALTER-
NATIVE TO FASTENING THE
STRAP.
