ity as follows:
Adjust helmet sensitivity in light-
ing conditions helmet will be
used in.
Turn sensitivity control to lowest
setting.
Face the helmet in the direction
of use, exposing it to the sur-
rounding light conditions.
Gradually turn sensitivity setting
clockwise until the lens darkens,
then turn sensitivity control
counterclockwise until slightly
past setting where lens clears.
Helmet is ready for use. Slight
readjustment may be necessary
for certain applications or if lens
is blinking on and off.
