3. 사용 설명서
This section provides a guide to the various functions and operations of your Casio fx-300MS Plus 2nd Edition Scientific Calculator.
3.1 기본 계산
Enter numbers using the numeric keypad and perform operations using the [+], [-], [×], 그리고 [¶] 버튼. 누르다 [=] 결과를 표시합니다.
3.2 과학적 함수
The calculator offers a wide array of scientific functions. Many functions are accessed by pressing the [옮기다] key followed by the desired function key (indicated in yellow above the keys).
- 삼각 함수: 사용 [죄], [코사인], [탠 껍질] 사인, 코사인, 탄젠트에 대한 역함수(sin⁻¹, cos⁻¹, tan⁻¹)를 통해 접근합니다. [옮기다].
- 대수: 사용 [통나무] for base-10 logarithm and [ln] for natural logarithm.
- 힘과 뿌리: 사용 [x²] 정사각형의 경우, [√] for square root, [x³] for cube, and [³√] for cube root. General powers ([^]) and roots ([SHIFT] [^]) are also available.
- 팩토리얼: 사용 [x!] (접근 경로: ) [옮기다]) for factorial calculations.
3.3 Fraction Calculations
The dedicated fraction key [알파벳] allows for easy entry and calculation of fractions and mixed numbers. Use [SHIFT] [a b/c] to convert between improper fractions, mixed numbers, and decimal equivalents.
3.4 통계 계산
To enter Statistics Mode, press [방법] and select the appropriate statistical option (e.g., SD for standard deviation, REG for regression). Follow the on-screen prompts to input data and perform calculations.
3.5 Variable Memory
The calculator can store up to 9 variables (A-F, X, Y, M). To store a value, enter the number, press [스토], and then press the alpha key corresponding to the desired variable (e.g., [ALPHA] [A]값을 불러오려면 누르세요. [RCL] and the variable key.

4. 유지관리
4.1 청소
To clean the calculator, use a soft, dry cloth. For stubborn dirt, lightly dampen the cloth with water and a mild detergent, then wipe dry. Avoid using strong solvents or abrasive cleaners, as these can damage the calculator's surface or display.
4.2 보관
When not in use, store the calculator in its protective hard case to prevent scratches and damage. Keep it away from extreme temperatures, humidity, and direct sunlight. The solar panel requires light to function, but prolonged exposure to intense heat can be detrimental.
4.3 배터리 교체
If the display becomes dim or calculations are slow, even in good lighting, it may be time to replace the LR44 backup battery. Refer to section 2.1 for battery installation instructions.
5. 문제 해결
- 디스플레이가 비어 있습니다: Ensure the calculator is in sufficient light for the solar panel. If it remains blank, replace the LR44 backup battery.
- 잘못된 결과: Check the current mode (e.g., degrees vs. radians for trigonometric functions). Press [SHIFT] [MODE] to access setup and adjust settings. Ensure correct input of numbers and operations.
- 계산기가 멈췄습니다: 를 누르세요 [AC] button to clear the current calculation. If the issue persists, try removing and reinserting the battery to perform a hard reset.
- 버튼이 반응하지 않습니다: Ensure no debris is lodged under the keys. Clean the calculator as described in section 4.1.
