Winding the motor
Move the side release to STOP and the motor dis-
engaging lever to MOT. Lift the motor winding handle,
which automatically engages with the spindle, and
turn anti-clockwise. Wind the spring motor fully but
without forcing it, then lower the handle and secure
it on catch (a). Otherwise, there is a risk of it turning
with the motor during filming.

Filming speeds
The camera has seven filming speeds: 12, 16, 18, 24,
32, 48 and 64 frames per second.
To select the desired speed, turn the control knob (b)
until the corresponding figure is opposite the red dot.
When the film is projected at normal speed (18 or
24 f.p.s.), a lower filming speed will produce an accel-
erated motion effect while a higher filming speed will
give a slow motion effect. When chan in filmin seed,

changing from 24 to 32 f.p.s., the diaphragm should
be opened half a stop, from 24 to 48 f.p.s. by a whole
stop and from 24 to 64 f.p.s. by 1% stops (see page 12).
