the Exposure Meter

near the right-hand edge
of the transparent window.
Should this occur, place
your hand close in front
of the Exposure Meter
Window and watch the

needle moves when you
block the meter cell the
exposu re meter is able to

movement occurs when
you place your hand in
front of the meter cell the
existing light is
insufficient and the
exposure meter cannot
be used. In this event,
either a time exposure
or use of a flash gun is
recommended.
