Page 17

For normal operation set the White Dot of the Shutter Release Selector

(A)against the White Square Dot Cl. When set to the Red Dot 0, the Release Button is locked.

*Select this mode if the camera will be idle for a period and to prevent accidental shutter re- lease. Also when the Power Drive Grip is used.

When set to the yellow clock symbol 0 the self-timer is operative. See page 27 and 28 for further instruc- tions.

Operating the shutter Release Button

1.The Shutter Release Button @ functions in two steps. Gentle pres- sure will light the metering informa- tion display if the AE Prism Finder is used. Continued pressure will re- lease the electromagnetic shutter.

2.If the film is not completely ad- vanced, if the Dark Slide is not with- drawn or if the battery is dead, the shutter will not function, even when the Shutter Release Button is pressed. This will also be the case if the Shutter Speed Dial is set to “A” or “AEL”when the AE Prism Finder is not attached.

3.After releasing the shutter, the Film Advance Crank will automati- cally unlock and be ready to advance the film.
