Casio CZ/ VZ/ FZ - Pro Series

Now I had read installation manual for Artefacts battery mod.

Questions:

Are you absolutely sure you followed all steps during the  
installation, and everything is well done, jumper desoldered and away  
from the instrument, traces cut properly, cables well soldered where  
they should be, no short circuit or something like this?

Does instrument work without the cartridge connected as it should work  
- especially writing the patches into internal RAM, keeping the memory  
contents after switching off and so...

Have you checked and set 3.2 Volts with that trimmer described in the  
installation manual?
