Some of the older Casio Chinese-English dictionaries have the ability to change the Menus to either Japanese, English, or Chinese
(maybe E-A99, E-G200, etc?
). The older Casio Japanese-English dictionaries don't typically have this feature although newer ones might. This is instructions to change the menus to English:

There is a different Casio electronic dictionary
(E-A10
) that has English menus. I think these were only sold to schools but maybe there is something used available in Vietnam.
