PREPARATION & USE
ADJUSTING THE HEADBAND TO FIT
1. The headband should be
adjusted both in diameter and
height to fit the wearer’s head. To
do this, turn the adjustment knob
on the back of the headband
either left or right to expand or
contract the headband.
2. The top headband can be
adjusted by bending the strap
and positioning the peg in the
appropriate hole.
3. The working position of the
headshield and its raised position
can be pre-set.
4. Loosen the adjusting nuts until you
can lift the adjusting tab and
position it against the backing
plate to set the headband range
of movement. Tighten the
adjusting nut when satisfied.
5. You can remove the headband
completely from the headshield by squeezing the side clips together and
sliding it away from the adjusting knob assembly.
PREPARATION AND TESTING
1. Remove the protective film from the outer lens cover.
