AGFA Automatic 66 Instructions For Use Manual page 14

The release button (10) situated next to the transport knob should on no account be
pressed during film winding, as this interferes with the counting mechanism.
After closing the back, the transport knob should be wound on until resistance is felt, or
until the knob can no longer be turned in the direction of the arrow. At the same time,
the counter window (11) next to the transport knob shows that the counting mechanism
has moved from 'A' to the number 1, and the film is ready for the first exposure. For
each following exposure, the transport knob should be wound on to a stop; numbers 1 –
12 will then appear automatically in the counter window.
Note! The frame counter, as
well as the shutter release only
work with film in the camera.
Neither can be tested with an
empty camera.
