Occasionally, the exposure meter gets out
of adjustment, This is due to altitude, tem-
perature or a slight jar. Red pointer on
LIGHT VALUE scale should be at "zero"
when meter is held in horizontal position,
and no light is falling on photo-cell window
(A). To reset, cover the window with your
hand. Then turn screw (E), either right or
left, until red pointer is exactly on zero.
