1. Turn Switch C so that the red dot lines up with the green dot. This selects continous filming mode.
   
   
2. Turn Switch D so that the 16 on the outside ring lines up with the red dot at the top.
   
   
3. the the inside switch of D back so that the dot on the inside switch lines up with the X on the outside ring.
   
   
4. now turn Switch B counterclockwise so that the left dot on the inner knob lines up with the red dot on the outside. This is what you would do after having put a film in as it trips the film counter mechanism. Apparently an accoustical signal will be given when the film leader is through, then the counter moves further and you should stop shooting at around 7.5 meters (film length) but an audible signal will be given again when you shoot stop filming.
   
   
5. Anyway, you can now wind the clockwork by turning Winding Key A clockwise. Mine seemed to be stuck but a little more pressure solved that. When winding you won't need to let it loose and turn your hand because you can turn it anti-clockwise and then wind further by turning clock-wise.
   
   You can check the status how far it's wound by checking the axis in the center of the winding key. When the red line on the round sides of the axis line up with the winding key, there's only 10 seconds left. When the red line sticks out more, there's less than 10 seconds left and when the axis has retracted inside the winding key, the clockwork is wound and there's over 10 seconds left (up to 2.5 minutes when wound fully).
   
   
6. Of course there are many other settings such as the light meter, lens, aperture and things but this should get you started.
   
   
7. Now, for filming, press the shutter button on the back. The top one, i.e. the one that sticks out, is for manual operation, the bottom one is for fitting a cable release. Now press the manual shutter button and the motor should start running, the film should start winding and your making a movie... :o)
8. All C3 Series film cameras have a single-exposure mode. Simply pull the button with the remote release socket (at the back of the camera) and one single frame is taken. Pushing this button makes for normal filming action.
