Canon V - Manual (Page 27)

For copying stand work, etc. the Manual Film
Winding Knob (1) is used instead of the Rapid Wind
mechanism.
Align the three engraved black dots on the top of
the Manual Film Winding Knob and rai.se this Knob
to facilitate control.
Turn the knob clockwise until it locks into position.
Your film has then been advanced one frame, the
shutter has been rewound and the Film Frame Dial
set to the next number. Keep the Rapid Wind Trigger
in its bed.
Before using the Rapid Wind Mechanism again, be
sure to return the Manual Film Winding Knob back
into its lowered position, by first depressing the Manual
Film Winding Knob Release Button (29).
