600/600 SE Camera
User Guide
Assembly (Picture 4)
Attaching the lens (Model 600 SE only) Insert the lens, aligning the red dot on the lens barrel with the red dot on the camera body (4). Turn the lens clockwise until the red dot is directly on top and the lens locks in place. Screw the end of the cable release into the cable release socket on the lens (5). Before removing a lens, unscrew the cable release from its socket on the lens and hang it on the cable release holder on the hand grip (6). (The cable release is permanently fixed to the handle and cannot be removed.) If there is film in the camera, be sure the dark slide is inserted before removing the lens. To detach the lens, press the lens release button and turn the lens counterclockwise (7). Always place the body cap on the camera when storing it without the lens, and keep both front and rear lens caps on the lens. To attach the body cap, fit it into the lens mount and turn it clockwise one-eighth of a turn (8). Eyecup Fit the rubber eyecup over the viewfinder eyepiece (11).
Lens hood Screw the collapsible rubber lens hood onto the lens (12). For best picture-taking results, a lens hood should always be used. For storage, you may fold it back over the lens barrel and put on the lens cap.
Film holder The removable film holder is attached to the camera by means of two sliding locks on either side of the camera body (13). When attaching the film holder, be sure it is properly seated and that the film tab slot is on the opposite side of the camera from the hand grip (14). If there is film in the holder, be sure the dark slide is inserted before removing the holder.
Neckstrap Attach the neckstrap as shown for the Model 600 (9) and the Model 600 SE (10).
