Once you have the official Casio fx-50FH II manual PDF, you can solve the language change problem even if your calculator's screen is frozen in a foreign script.

Since you are dealing with manuals and settings, here are three advanced tips to make your fx-50FH II experience better:

First, a crucial clarification. Unlike scientific calculators sold in Europe (which often feature English, French, German, and Spanish menus), the fx-50FH II is a region-specific model designed primarily for the Hong Kong and China markets.

The core menu of the fx-50FH II is predominantly English. It displays words like "COMP", "STAT", "EQN", and "MATRIX". However, the calculator does support two specific language variations in its setup menu:

The "language change" users are searching for usually refers to switching the displayed language of messages, error alerts, and input prompts from Chinese back to English, or vice versa.

If your calculator is currently displaying Chinese characters for terms like "Syntax Error" (语法错误) or "Math Error" (数学错误), you need to perform a language reset or modification via the system settings.


The official PDF is great for syntax, but it does not teach you exam strategy. Because the fx-50FH II is programmable, the manual shows you how to enter formulas (via [PRGM] mode), but it does not tell you that you must clear your memory before an HKDSE exam. (Check the latest HKDSE regulations, but usually the examiner requires a memory clear – [SHIFT] [CLR] [1] (Mode)).

If you lost your physical manual, you do not need to panic. Follow these keystrokes exactly. Even if your screen is currently in Chinese, the button locations are identical.

If your screen is stuck in Chinese and you cannot navigate the menus, a factory reset will force the calculator back to its default language (English).
