To use your Casio fx-9860GII for the HAVO or VWO exams, you have :
- either to put it into exam mode if it's running OS version 2.07 or higher
- or to reset its memory
Starting from 2018 for the HAVO and then 2019 for the VWO, the exam mode and thus OS 2.07+ become mandatory.
But don't be eagle to junk your old fx-9860GII, or to buy a brand new one !
You may be able to update it, and this isn't going to cost you anything !
So you may keep your old one or buy a used one for cheap.
You first have to determine your calculator hardware version and thus the used CPU type : either SH3 or SH4.
There are 2 very easy ways for this :
- Look at the label below the screen. It'll be showing :
- USB POWER GRAPHIC 2 for an SH4 calculator
- USB POWER GRAPHIC for an SH3 calculator
- Check the full OS version string in the SYSTEM application :
- type
MENU
, then go into the SYSTEM application - type
F4
to get the system version
You should have the full version string displayed in the XX.XX.XXXX format, with a digit in place of each X character. - Look at the last digit, thus the 8th one with this format. It will be :
- 1 for an SH4 calculator
- 0 for an SH3 calculator
- type
SH3 calculators cannot be updated with the exam mode.
But for SH4 calculators, just download and install the fx-9860GII 2.09 OS update.
