The camera can be loaded under ordinary soft
lighting conditions in the following way:
by turning the nut on the case bottom
unscrew the tripod screw retaining the camera;
remove the camera from the case. Raise the lock
shackles with the nail and turn them half-way
round as far as they go.
Then, pressing with the thumbs, shift the
camera back in such a way that its edge comes
out of the camera slot and remove it.
Take the take-up reel and the magazine out of
the camera. The reel is removed with a certain
amount of effort.
Load the magazine with a film (the magazine
is loaded in the darkness).
Having pulled out the free end of the film
about 10 cm long from the magazine, fasten it
on the reel in such a way that the spring tooth
enters one of the film perforations.
