INSERTION OF FILM
The Arelte is designed for the perforoted miniqlure film (35 mm)
normolly supplied by lhe lrode in rolls ol 20 or 35 exposures (size
24X36 mm).
To operr lhe bock of fhe comero fhe lwo milled knobs ore pressed
ogoinst eoch olherwilh thetlrumb ond index f inger of lhe right hond.
The lopered end of lhe film, projecling from the film corfridge, is
.folded lhrough lhe middle ol the fhird perforolion hole (A) in such
o woy thot, when lopered end of lhe film is pushed through lhe slof
(morked wifh o red dot) of lhe foke-up spool, fhe red clip of this
lotler enlers inlo lhe soid lhird perforolion hole (B). The film lhus
is proiected ogoinsl ifs being pulled oul during the winding operotion.
The film cortridge is lhen inserled inlo lhe cossetfe chomber of lhe
comercr, sller the bockword winding knob (10) hos been fully
exlended. A.s soon os lhe cosselfe is in its correcl posilion, lhe re-
wind knob (10) is pushed bock ond by lurning in the direclion o{
the orrow lhe film is stioighlened, so lhot it lies on lhe focol plone.
The bock woll con now be reploced. Before loking phologrophs
lhe film should be odvonced os described on poge 5.View original page 6Page 7 · Read text
FILM TRANSPORT
To odvonce film, move tronsport lever (2) os for os it will go. The film con be odvonced
only by fhe lenglh of one frome ol o time, since the buill-in inferlocking device prevents
double exposure. To ensure uniform spocing of exposures on your film, foke core lo
move the quick-oction universol lever (2) to its full exlent. The frome-counler (22) moy
otherwise foil lo show the correcl number, lhough this is o minor moller with no beoring
wholsoever on lhe performonce of the ARETTE, being complelely concelled oul on the
nexl winding oction.
FRAME COUNTER
When the film hos been inserled, the film slrip prolruding from lhe cosselfe will olwoys
olreody hove been exposed. Belore lhe first exposure is mode, lhis seclion of the film
should be odvonced by lwo or lhree lurns (lronsport ond releose). Only when fhis hos
been done should lhe frome counler disc (221 be brought to ils slorting position by de-
i pressing the knurled knob wilh lhe finger tip ond setting the disc, by movement lo righl or left, of "O".
FILM INDICATOR
lmmediolely ofler inserlion of f ilm, the lilm indicolor (23) must be set ot
its correcl volue. To do this, depress the smoll knurled bullon wilh lhe
lip of your finger. The indicolions "Colour posilive", ond "Colour
