Casio Fx-50fh Ii User Manual [ BEST - 2025 ]

You’ll find a full table in the manual listing constants like:

The manual also covers unit conversions (e.g., °C to K, cm to m, J to eV). Memorizing the constant numbers is a huge time-saver in physics.

The manual clearly explains the calculator’s modes:

Pro tip: The manual points out a common error – forgetting to exit PROG mode before an exam. Stay in COMP unless you’re running a stored formula.

Many students toss the manual aside thinking, “I already know how to type in numbers.” That’s a mistake. The fx-50FH II is different from basic calculators in three key ways: casio fx-50fh ii user manual

Skipping the manual means you’ll waste exam time hunting for keys.

Without a manual, users panic. Here are three "fatal errors" and fixes.

Error 1: Math ERROR

Error 2: Syntax ERROR

Error 3: Low Battery (Even with solar)

Q: Does the manual show how to store constants like the speed of light?
A: Yes. Page 15 covers the 40 built-in constants. Press CONST (orange key above 7) then select from the list. The manual gives the SI values.

Q: Where is the manual’s index for matrix operations?
A: There are no matrix operations. The fx-50FH II is not a graphing calculator. If you need matrices, refer to the manual’s "EQN" mode for linear systems.

Q: Can I get a printed replacement manual in Hong Kong?
A: Yes. Go to any major bookstore (Commercial Press, Joint Publishing) with a calculator section, or contact Casio’s distributor in Tsim Sha Tsui. They often provide free PDFs on USB, but printed copies may cost HKD 30. You’ll find a full table in the manual

Q: The manual mentions "SD Mode" but doesn’t clearly explain how to enter data.
A: Actually, it does on page 18. After pressing MODE + 2 (SD), type a number, then press M+ (the DT key). Repeat. To delete an entry, type the number and press SHIFT + M+. This is critical for statistics.

It is worth noting that the manual explains how to reset the calculator. This is vital because the fx-50FH II is an exam-approved model. The manual correctly instructs users on how to clear memory to comply with exam regulations, but it buries this information. It should be a highlighted "Warning" or "Pre-Exam Checklist" box, rather than a small paragraph in the memory section.

Before diving into key sequences, it is crucial to understand what makes this model unique. Unlike standard scientific calculators, the fx-50FH II is Permitted for HKDSE Examinations. It features:

The official manual glosses over the programming aspect. This guide will focus heavily on that. The manual also covers unit conversions (e

The manual highlights errors that appear on forums again and again:

| Mistake | Fix from manual | | --- | --- | | “Syntax ERROR” in a program | You forgot a colon (:) between commands | | “Can’t solve” in EQN mode | Equation must be arranged as ax²+bx+c=0 first | | Constants don’t match exam data | Use SHIFT + CONST + (number) – verify against your formula sheet | | Program won’t stop | You need ◢ (output) or :0→A to terminate loops properly |
