Hi,


Interesting images.

On the fx-82 ES, it was possible to change the calculator model and unlocking new functions by closing some P0-P7 jumpers.


On my fx-82 ES Plus, the P0-P7 jumpers are still there, but none of them is closed - as we can see on an above image.


I allready tried to randomly close some jumpers but couldn't notice any change in the calculator behaviour.


Is there a way? Why are those jumpers here if they are useless?


Thanks.

Hi,

The program in PLUS series are different(We can learn it from diagnostic MODE, the SUM are different, but you could see the Pd are different with different jumpers closed).
Also, the CASIO Customer support center gives the following answer:
"
As you question is about overseas' products,

we would like to answer your question in English

from us.



If you are talking about FX-82ES PLUS and FX-991ES PLUS,

both models' program is different.

However,BASE-N MODE is basic function.

"
We had found that the 82ES PLUS only has the extra BASE-N mode in 2012(Video Link, the first one:http://tieba.baidu.com/p/1422515868).
So the jumper didn't work at all because of the different program.
