TURN RING
Place the helmet on your head. Turn the ring clockwise
until the headband is firm yet comfortable.If you need
to loosen the headband, TAKE HELMET OFF, turn the
ring counterclockwise. All fit adjustments must be made
with the helmet in the proper position. Failure to do this
will result in a poor fit. A poor fit will allow the helmet
to move out of position or come off in an accident.For
a proper turn ring operation, refer to Figure 1. For a
proper position, please refer to Figure 8.
