From CASIO FAQ:


How do change the currency rate?

When you press the [M/EX] key, it toggles between conversion mode and memory mode. You will see "EXCH" on the display when in conversion mode.
C1, C2, and C3 are three conversion rates. C1 is your home country currency, and so it is always set to 1. C2 and C3 are rates for two other countries, which you can change.
For example, if you want to set a conversion rate of $1 to 0.95 euros, here is what you would do (using C1 for US dollars and C2 for euros):
1. Press [AC]
2. Hold [SET/%] for about two seconds until "SET" appears
3. Press [C2] to select currency 2
4. Input the conversion rate (0.95) and then press [SET/%] to store it in memory
You can check the currently set rate at any time by pressing [AC] and then [C2].


How do I perform a currency conversion?

If you want to convert 100 euros to US dollars, you would do the following (assuming you are using C1 for US dollars and C2 for euros):
1. Press [AC]
2. Enter 100 and then press [C2]
3. Press [C1] to convert to dollars
4. To convert back to euros again, press [C2]
You can also perform a currency conversion within a calculation. How much in US dollars would five items selling at 100 euros cost?
1. Press [AC]
2. Enter 5 [×] 100 and then press [C2]
3. Press [C1] [=]

1. Press [AC]
2. Hold [SET/%] key for about 2 seconds
3. Press [TAX+]
4. Input the tax rate
5. Press [SET/%]

For the MS-80TE and MS-100TV this suggestion works - with the MODE select the EXCH than hold down the SET button. on the screan SET EXCH will appear, press the C2 /the C1 is by default 1/ and set the rate, press SET again and you are done
