Olympus AZ-4 Zoom - Manual (Page 17)

Unloading the Film
When you reach the end of the film, it will
rewind automatically. You will hear the
"beep-beep" sound indicating that the film
has been rewound fully.
If you want to rewind the film in the
middle of a roll, open the mode cover and
press the rewind button.
* The final reading of the exposure counter
prior to rewinding may be more than the
number of exposures specified for the
film.
