Olympus OM-2 - Manual (Page 14)

SETTING THE SELECTOR LEVER
The selector lever on top of your camera has four
positions as follows (with click stops at
AUTO-OFF-MANUAL):
1) AUTO — Automatic exposure control; you
preset the F stop and the camera automatical-
ly sets shutter speed for proper exposure.
2) OFF — Camera turned completely off to avoid
battery drain. Always store your camera with
the selector lever in this position.
3) MANUAL — Zero-method exposure operation;
set shutter speed and F stop for proper ex-
posure (see page 17).
4) CHECK•RESET — Battery test position simul-
taneously with release of mirror lock-up.
The three-position viewfinder control center
allows you to see the operating mode of your
camera without checking the position of the
selector lever.
NOTE: If you release the shutter with the selector
lever at OFF in normal lighting condition, the
built-in automatic exposure control is activated
to take a properly-exposed picture, so as not to
miss optimum exposure opportunity, at any mo-
ment. The difference between the automatic ex-
posures in the OFF position and the AUTO posi-
tion, however, is that the OFF mode exposure
stops in 1/30 sec. maximum to save battery ex-
haustion, and the AUTO viewfinder scale does
not appear.
