Change battery on a Fujifilm FOTONEX 1000ix MRC TIARA

Hi
I've been trying to figure out how to change the battery on my Fujifilm1010ix MRC TIARA.
I tried to google for a manual but nothing came up.
All that I could find is that I need to take the camera apart.
Anybody here who has changed the cattery in this type of camera before?

Never even heard of that model...

But when extracted, at the back there seems to be a flap (with that sliding switch), with a groove as those to insert a coin to make a flap spring open.

No slot for a coin on my model.
There is a flap that awings open but that is for loading the film in to the camera.

Great, super thanks that was it.

Got an error message after loading the film though, but after some light investigation it seems like the previous owner already exposed the roll that came with the camera.
Need to find a new roll of APS-film and develop the old.
