Convert a Casio fx-350MS Calculator into fx-570MS

In secondary school, the scientific calculator usually used by students include Casio fx-350MS and fx-570MS. Casio fx-570MS has more functions than fx-350MS. Students who had bought Casio fx-350MS may regret. However, it is possible to convert a Casio fx-350MS into fx-570MS.

After the conversation, however, not all fx-570MS functions will be available. The keys layout will change, some following fx-350MS, some following fx-570MS and some different from both 350MS and 570MS. You have to test it out by yourself. These are the functions added to the fx-350MS calculator after conversation.

COMP, SD and REG mode: Added CONST and CONV function only. Other fx-570MS functions are still unavailable.
CMPLX and EQN mode: All functions will be available.
BASE-N mode: All functions will be available except some LOGIC functions.
MAT and VCT mode: No function available. Matrix and vector cannot be used.

To convert, follow these steps:

1. Press [MODE] and select 2 (SD).
2. Press 1.
3. Press [M+] eighty-two times until it displays "EditOFF ESC"
4. Select 2 (ESC).
5. Press ^ (REPLAY UP).
6. Press 131313131... until no more numbers could be entered.
7. Press [=] two times. It should display "EditOFF ESC"
8. Press [0] followed by [1]. Note that you must press [0].
9. It should display "1          _". Press [AC].
10. Press [MODE] and you will notice that your calculator has the fx-570MS functions. Well done.

To cancel and return to fx-350MS, just press [ON]. Start over from step 1 to convert again. So if you want to remain in fx-570MS, you can only press [AC].

NOTE:
1. The method above may not work for some older or non-original versions of fx-350MS calculators. For those calculators, you may not be able to press [MODE] at step 10, or the screen may show some strange displays. In that case, it is not possible to convert the 350MS calculator into 570MS.
2. The method above will not work for fx-350ES (Natural Display) calculators.
3. As I stated above, after converting your fx-350MS calculator into fx-570MS, only some but not all fx-570MS functions will be available. Also, the keys layout will change.
