Casio CZ/ VZ/ FZ - Pro Series

Felipe,

People have talked about isolating the data memory circuit, but I
don't think anyone ever tried it.  See this message:

I don't think you need to isolate the memory circuit, because you can
just connect a small voltage to the battery terminals and it will work
the same.  The battery terminals are already connected to the memory
circuit in the appropriate way!
