Film Advance Lever (§)
The film advance lever is coaxial w/ith the shutter release button
®
and is specially contoured to fit the thumb. To advance the
film, wind the lever to the right all the way until it stops. It auto­
matically returns to the standoff position the moment you take
your thumb off it. One complete stroke or a series of shorter
ones advances the film by a sihgle frame and simultaneously
cocks the shutter.
At the end of the film roll, the lever stops working. Do not attempt
to wind the lever further; just rewind the film.
Note: If the lever becomes difficult to operate at the beginning of the
roll, this means that the film is not winding onto the takeup spool ® prop­
erly. In this case, rewind the film immediately and load the film again.
