Dismantling for internal inspection.

Well, I have to see my ophthalmologist. When I replaced the old batteries for new ones, I didn't notice a small amount of battery leakage in one of them.
Nothing serious, as the main board has got a plastic protection under the battery compartment for such eventualities.

Time for reassembling.
Working with these Casio machines is as easy as it gets on small pocket machines.
A few screws to be set and that's about it.
If done carefully, there will be are no traces left that the machine was opened.
