FILM MAGAZINES
Changing the magazines (Figs. 28—29)
Make sure the indicator windows (19 and 20)
are displaying white signals whenever maga-
zines are changed. Insert the magazine slide
(41). Slide the magazine release catch (28) to
the right and swing down the magazine on the
two lower support catches (40). The magazine
slide protects the film from fogging if the
magazine is detached from the camera. The
magazine is attached to the camera as
follows:
Hook the magazine onto the lower magazine
support catches (40) and make sure the con-
nection is secure. Then swing the top of the
magazine up against the upper catches (A)
while simultaneously pushing the magazine
release catch (28) to the left. Release the catch
and then push it to the left to make sure the
magazine is securely locked in place. Remove
the magazine slide.
NOTE А magazine can only be detached
when the magazine slide is inserted.
No exposure can be made until the
magazine slide is withdrawn from the
attached magazine.
Loading the magazine
The magazine can be loaded on or off the
camera. When the magazine is loaded off the
camera, the magazine slide (41) must be in-
serted with the curl of its handle retainer
facing the roll holder key (42).
