During Use
If the Helmet is not secure and comfortable on the head, it may be
necessary to change the Height Adjustment. The Height Adjustment
raises and lowers the rear headband and the angle of the helmet with
respect to the head, and properly positions the DLC Lens from the
chin. This optimizes a secure and comfortable fit in conjunction with the
Adjustment Knob for optimizing the circumference of the Headband. It
also aids in proper positioning for easy visualization of the LED Safety
Status Indicators. If necessary, unsnap the Height Adjustment tabs on
each side of the Helmet Liner and reposition upward or downward, until
the optimum fit for comfort and security is determined.

CAUTION
Optimum setting is achieved
when the helmet is secure on
the head for all movements
required and the front headband
is within 1/2 inch of the eye-
brows to allow good visualiza-
tion of the LED Safety Status
Indicators in the upper periph-
eral vision. Be sure to have both
Height Adjustment tabs in the
same position.
