LOADING OF CAMERA
The ARETTE tokes the perforoted minioture fllm (35 tt),
ovqiloble in the stondord cossette for 20 or 36 exposures
(24x36 mm).
                                                                    toTo open the comero bock the two locking buiions Q\ ore

your right hond. The topered end, overlopping from the cos-
setie hos to be folded through the middle of the third perforo-
tion hole (A) thotwhen inserting the folded end into the slot of
the spindle the red hook will feed the third perforotion hole.
This ovoids ony pulling out of the fllm when winding up.
The fllm coriridge hos to be inserled into the cossette chomber
of the comero ofter therewinding knob (23) hos been fully pull-
ed out. Hoving inseried the cossette the rewinding knob hos to
be pushed in ogoin ond by turning the knob in the direction of
the orrow the fllm is stroightened ond lies on the focol plone.
Now the comero bock will be closed. Before toking the first
picture the film should be qdvonced os described on poge 6.

 For sofety tronsport the ropid lever wind (25) must be turned uniil the stop. At the
some time the film will be tronsported, the shuiter cocked, ihe exposure counter
operoted qnd the double exposure lock put in. The reverse motion of the ropid lever
wind works outomoticolly.
EXPOSURE COUNTER
The film which is pre-exposed by inserting some must be removed by 3 blonk
exposures (tronsport ond releose) in order to hove unexposed film on the focol plone
for the first exposure. The exposure counter (26) will be put into its bosic position "0"
by pressing ond iurning to the left or right.
Accurote counting is only guoronteed by in-
serted film. Moreover it shows - before snopp-
ing-which picture is reody for exposure.
