2. 初期設定
2.1 電源
The EL-W516TBSL calculator utilizes a twin-power system, combining solar power with a battery backup. In well-lit environments, the calculator primarily uses solar energy. The battery provides power when lighting is insufficient, ensuring continuous operation. No initial battery installation is typically required as the unit comes with a pre-installed battery.
2.2 電源のオンとオフ
- 電卓をオンにするには、 オン/C ボタン。
- 電卓をオフにするには、 2階 続いて オン/C button. The calculator will also automatically power off after approximately 10 minutes of inactivity to conserve battery life.
3. Operating Modes and Key Functions
3.1 書き込みView™ Display
書き込みView™ display allows you to input and view mathematical expressions in a natural, textbook-like format. This feature simplifies complex calculations by presenting them clearly on the 4-line LCD.
3.2 主要機能view
The calculator's keypad is organized for efficient operation. Key categories include:
- Numeric Keys (0-9, .): For entering numbers.
- Operation Keys (+, -, ×, ÷): For basic arithmetic operations.
- ファンクションキー: Access various mathematical functions (e.g., sin, cos, tan, log, ln, square root, power). Many keys have secondary functions accessed by pressing 2階 初め。
- Memory Keys (STO, RCL, M+, M-): For storing and recalling values.
- Mode Key (MODE): To switch between the 7 operating modes.
- ホームキー: Allows users to return to the Normal Mode from any screen.

3.3 Advanced Functions and Modes
The EL-W516TBSL offers 640 functions and 7 distinct modes to handle a wide range of calculations:
- 通常モード: Standard arithmetic and function calculations.
- STAT Mode: Statistical calculations, including mean, standard deviation, and regression analysis.
- DRILL Mode: Practice arithmetic and multiplication tables.
- COMPLEX Mode: Calculations involving complex numbers.
- マトリックスモード: Matrix operations, up to 4x4 matrices.
- LIST Mode: List-based data entry and calculations.
- EQUATION Mode: Solving linear equations and polynomial equations.
Refer to the full user guide for detailed instructions on using each mode and its specific functions.
4. メモリ機能
The calculator includes 8 temporary memory buttons and 3 definable memory buttons for storing numerical values or expressions.
- Storing a Value (STO): Enter the value, press STO, then press the desired memory key (e.g., A, B, C).
- Recalling a Value (RCL)： プレス RCL, then press the desired memory key to retrieve the stored value.
- Adding to Memory (M+): 表示されている値を独立メモリに追加します。
- Subtracting from Memory (M-): Subtracts the displayed value from the independent memory.
5. メンテナンスとケア
Proper care ensures the longevity and optimal performance of your calculator.
5.1 クリーニング
電卓の外側は、柔らかく乾いた布で拭いてください。頑固な汚れには、軽くampen the cloth with water and mild soap, then wipe dry immediately. Avoid using harsh chemicals, abrasive cleaners, or solvents.
5.2 ストレージ
When not in use, store the calculator in a cool, dry place, away from direct sunlight and extreme temperatures. The included slide-on hard case protects the display and keys from damage.

6。 トラブルシューティング
If you encounter issues with your calculator, refer to the following common solutions:
6.1 表示の問題
- 空白の表示: Ensure sufficient lighting for solar power. If the issue persists, the battery may be depleted.
- 暗いディスプレイ: Move to a brighter area. The display contrast might also be adjustable in the calculator's setup menu.
6.2 Calculation Errors
- "ERROR" Message: This typically indicates an invalid mathematical operation or syntax error. Review your input and the function's requirements.
- 誤った結果: Check the current operating mode (e.g., ensure you are in Normal mode for basic calculations, or the correct angle unit (DEG/RAD/GRAD) is selected).
6.3 Resetting the Calculator
If the calculator behaves erratically, a soft reset may resolve the issue. Press the リセット button (usually a small recessed button on the back, requiring a thin object like a paperclip) or clear all memory via the M-CLR 機能（多くの場合 2階 それから M-CLR). Note that resetting will erase all stored data and settings.
