the battery chamber cover is reinstalled, the zoom lens
and motor operate for a few moments.)
Notes on replacing the batteries:
• Make sure there is no film loaded.
if the batteries are replaced with film already loaded the
camera behaves as if just loaded. Film advances
several frames, and the film counter will read / .
• Sometimes when the loaded film is at its end. no
indication will appear on the exposure counter of the
LCD panel, because the camera is unable to detect the
film. In such cases, press the auxiliary rewind button
before removing the film.
