SAFETY LOCK
When the Safety-lock is set at "l", the run-button cannot be
depressed. Therefore, before taking pictures the Safety-lock has to
be set at "R". To set for continuous exposure depress the run-button
and push the Safety-lock to "l". After the shot, be sure to push
the continuous run lock back to "R", or the camera will run while
you are winding the motor.
SINGLE FRAME EXPOSURE
By inserting a standard cable release into the socket marked "I",
you can trip the shutter to expose one frame at a time.
IA) With single-frame exposures you can make an animated cartoon
movie, or create time-lapse movies (of flower opening, for example),
or even make snapshots for enlargement.
(8) If the use of a cable release is preferred, screw the cable
releas3 into the socket provided in the run-button. The use of a
self-timer in the <:r:tf,'lO manner will enable you to get in the picture
yourself-
