• Should dust, foreign bodies or film residues
collect on the film holder or within the film holder
chamber of the camera body, they may
inadvertently register photographically; clean
them off carefully to prevent problems. Should
film residue or dust collect at the contact point
Ifor film detection) located on the pressure plate
side of the film holder, the motor will continue to
rotate idly after all remaining frames have been
exposed. However, in approximately 30 secs., the
motor will stop turning. When the motor
stops and the ON-OFF operation of the main
switch is repeated, the motor will again be
activated in idle rotation; however, avoid doing
this, since it may cause problems with the film
winding mechanism. After switching off, remove
the film holder and clean the contact point of
the pressure plate.
• Should the film winding operation stop before all
available frames have been exposed, recheck the
batteries in order to locate the possible cause of the
problem
• When using accessories without information
contacts, set the aperture ring to the appropriate
f/stops, with the exception of the "A" (auto)
position which cannot be used under this
situation.
