설정
전원
The Sharp EL-W531TG-WH calculator operates using both solar power and a backup battery (1 LR44 battery included). The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions.
배터리 설치/교체
- 계산기가 꺼져 있는지 확인하십시오.
- 계산기 뒷면에서 배터리 덮개를 찾으세요.
- 작은 드라이버를 사용하여 배터리 덮개를 고정하는 나사를 조심스럽게 제거하십시오.
- Remove the cover and replace the old LR44 battery with a new one, ensuring correct polarity (+/-).
- 배터리 커버를 교체하고 나사로 고정합니다.

작동 지침
전원 켜기/끄기
- 켜려면: 누르세요 켜짐/꺼짐 열쇠.
- 끄려면 누르세요 2번째 F 그 다음에 끄다 (usually located above the ON/C key).
Display Modes (WriteView / Line)
The calculator features a WriteView display that shows fractions, roots, and formulas as they appear in textbooks. You can switch to a traditional line mode if preferred.
- To toggle between WriteView and Line mode: Press 방법 and select the desired display option. Refer to the on-screen menu for specific selections.
기본 산술 연산
Enter numbers and operations in sequence. The D.A.L. (Direct Algebraic Logic) input method allows you to input equations exactly as they are written.
- 덧셈: +
- 빼기: -
- 곱셈: x
- 분할: ÷
- 같음: =
과학적인 기능
The calculator includes 414 pre-programmed functions covering statistics, n-base calculations, logical operators, trigonometry, logarithms, and more. Access these functions using the dedicated keys or by pressing 2번째 F followed by the key with the desired secondary function.
- 삼각 함수: 죄, 코사인, 탠 껍질 and their inverse functions (accessed via 2번째 F).
- 로그 함수: 통나무, ln.
- 전원 및 루트 함수: x², √, xʸ.
- 통계: Enter STAT mode via 방법 to perform statistical calculations.
- N-Base Calculations: Perform calculations in binary, octal, decimal, and hexadecimal bases.
메모리 기능
The calculator features 4 shortcut memory buttons (D1, D2, D3, D4) for quick access to frequently used functions or constants. Additionally, standard memory functions (M+, M-, RCL, STO) are available.
- STO(매장): Stores a value into a memory variable.
- RCL(회상): Recalls a value from a memory variable.
- M+ / M-: Adds to or subtracts from the independent memory.

유지
청소
계산기를 청소할 때는 부드럽고 마른 천으로 살살 닦아주세요. 연마성 세제, 용제 또는 젖은 천은 계산기를 손상시킬 수 있으므로 사용하지 마십시오.asing 또는 내부 구성 요소.
저장
When not in use for extended periods, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its protective cover to prevent scratches and damage.
배터리 관리
If the calculator will not be used for a very long time, it is advisable to remove the LR44 battery to prevent potential leakage and damage to the device.
문제 해결
디스플레이 문제
- 빈 화면: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- 희미한 디스플레이: This may indicate a low battery. Replace the LR44 battery.
Incorrect Calculations
- 잘못된 결과: Verify the input method (D.A.L.) and ensure all values are entered correctly. Check if the calculator is in the correct mode (e.g., DEG/RAD for trigonometric functions, STAT mode for statistics).
- 오류 메시지: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
계산기 재설정
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the small reset button (often on the back or side, requiring a thin object like a paperclip to press) or perform a soft reset via the 설정 menu. Note that resetting may clear all memory and settings.
