2. 설정

2.1 전원

The EL-546XTB-SL calculator is twin-powered, operating on both solar energy and a lithium-ion battery. Under sufficient lighting, the calculator will primarily use solar power. In low-light conditions, it automatically switches to battery power. The battery is pre-installed and typically does not require immediate replacement.

2.2 초기 전원 켜기

1. 를 누르세요 켜짐/꺼짐 key located in the upper right corner of the keypad to turn on the calculator.
2. The display will show '0' or the last calculated result.
3. If the display is dim or blank, ensure the calculator is exposed to adequate light or consider battery replacement if issues persist after prolonged use.

3. 사용 설명서

• EQUATION: Solves quadratic, cubic, and 3-variable linear equations.

3.5 메모리 함수

The calculator includes 8 temporary memory buttons and 4 formula memory buttons. Use 스토 (매장) 및 RCL (Recall) keys in conjunction with variable keys (A, B, C, D, X, Y, M, etc.) to manage stored values.

3.6 Equation Solvers

In 방정식 mode, you can solve:

• Quadratic equations (ax² + bx + c = 0)
• Cubic equations (ax³ + bx² + cx + d = 0)
• 3-variable linear equations (e.g., ax + by + cz = d)

Follow the on-screen prompts to input coefficients.

3.7 통계 계산

In 통계 mode, you can perform 1-variable and 2-variable statistical analyses. Use the 데이터 CD key to input data and access statistical results like mean, standard deviation, and regression analysis.

3.8 Physical Constants and Metric Conversions

The calculator includes a library of physical constants and metric conversion functions. Refer to the calculator's key markings and the 2번째 F or 알파 functions for specific access methods.

4. Key Functions Overview

The EL-546XTB-SL keypad is organized for efficient use. Below is a general overview of key groups:

• Numeric Keys (0-9, .): 숫자를 입력하기 위해.
• Arithmetic Operators (+, -, ×, ÷, =): 기본 계산용입니다.
• Function Keys (sin, cos, tan, log, ln, x², √, etc.): For scientific and mathematical operations.
• Mode Keys (MODE, HOME): To select operational modes and return to the home screen.
• Modifier Keys (2nd F, ALPHA): To access secondary and alpha functions.
• Memory Keys (STO, RCL, M+, M-): For storing and recalling values.
• Navigation Keys (Arrow keys): To move the cursor on the display for editing expressions.
• Clear/Delete Keys (ON/C, DEL, INS): To clear entries, delete characters, or insert characters.

5. 유지관리

5.1 청소

To clean the calculator, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the casing 또는 내부 구성 요소.

5.2 보관

When not in use, store the calculator in its protective hard case to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.

5.3 배터리 정보

The calculator uses one Lithium Ion battery (included). While the calculator is twin-powered, the battery provides backup power. If the display becomes consistently dim even in good lighting, or if the calculator fails to power on, the battery may need replacement. Consult a qualified technician for battery replacement to avoid damaging the device.

6. 문제 해결

• 디스플레이가 비어 있거나 어둡습니다. Ensure adequate lighting for solar power. If the issue persists, the battery may be low or depleted.
• Calculator does not respond: 를 누르세요 켜짐/꺼짐 key. If unresponsive, locate the 다시 놓기 button (often a small hole requiring a thin object like a paperclip) and press it gently. This will clear all memory and settings.
• 잘못된 결과: Check the current mode (e.g., DEG/RAD, NORMAL/STAT). Ensure correct input syntax, especially with parentheses. A reset may resolve persistent calculation errors.
• 오류 메시지: Refer to the calculator's on-screen error codes (if any) for specific meanings. Common errors include 'MATH ERROR' (invalid operation) or 'SYNTAX ERROR' (incorrect input format).
