HOW IT WORKS
A silver battery is packed separately.  Be sure to insert it into the
battery housing before operating the camera.  For insertion, refer to
page 19.
1.  Load your film and set ASA
film speed.
2. Keep this at "1x" for normal
exposure.
3. Pre-select f/stop
4. Set shutter speed dial at
"AUTOMATIC".
5. Keep this lever down for open-
aperture exposure reading.
(Lens aperture stays fully open,
and stops down to pre-selected
f/stop as you depress shutter
release.)  Move it up for depth-
of-field preview or for stop-down
exposure reading.  (Lens
aperture actually stops down to
pre-selected f/stop.)
