2. Setup and Power

2.1 Sumber kakuatan

The EL520XTBBK calculator is equipped with a dual power system: solar power and battery backup. The solar panel, located at the top of the calculator, provides power in well-lit environments. In low-light conditions or when solar power is insufficient, the calculator automatically switches to battery power. No user intervention is required for power source selection.

2.2 Hurungkeun / Pareum

• Pikeun ngaktipkeun kalkulator, pencét tombol ON/C kancing.
• To turn off the calculator, press the 2nd F tombol dituturkeun ku Pareum button (which is typically the same as ON/C, indicated by an orange 'OFF' label above it). The calculator also features an auto-power-off function to conserve battery life after a period of inactivity.

3. Parentah Operasi

3.1 Direct Algebraic Logic (D.A.L.)

The D.A.L. system allows you to input equations exactly as they are written, simplifying complex calculations. For example, ngitung sin(30), you would press dosa, tuluy 30, teras salajengna =. The calculator displays the expression as you enter it, making it easy to verify your input.

3.2 Basic Arithmetic and Scientific Functions

Perform standard operations using the number keys (0-9), decimal point (.), and operators (+, -, ×, ÷). The = key executes the calculation.

Access scientific functions such as trigonometric (dosa, cos, samak, hyp), logarithmic (log, ln), and exponential (Exp, 10^x, e^x) functions directly or by using the 2nd F key for secondary functions. The x², x³, √, jeung y^x keys are available for powers and roots.

3.3 Itungan Statistik

The calculator supports 1-variable and 2-variable statistical calculations. To enter statistical mode, press MODÉ and select the appropriate statistical option. Data entry and calculation of mean, standard deviation, and other statistical values are performed using dedicated statistical keys and menus.

3.4 Equation Solvers

The EL520XTBBK includes a 3-variable linear equation solver. Refer to the detailed manual for specific steps on how to input coefficients and solve systems of linear equations.

3.5 Fungsi Mémori

The calculator features 8 temporary memory buttons and 4 formula memory buttons. Use STO to store values into memory and RCL to recall them. The M+ jeung M- keys allow for direct addition or subtraction to the independent memory.

3.6 Physical Constants and Metric Conversions

Access a library of built-in physical constants and perform various metric conversions using the dedicated functions. Consult the full user manual for a complete list of available constants and conversion types.

4. Pangropéa

4.1 beberesih

To clean the calculator, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or alcohol, as these can damage the casing or display. Avoid getting moisture into any openings.

4.2 Panyimpenan

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

5. Cara ngungkulan

5.1 Masalah tampilan

• Tampilan kosong: Ensure the calculator is in a well-lit area for solar power or that the battery is not depleted. Press ON/C pikeun ngahurungkeun deui.
• Tampilan samar: Adjust the contrast setting if available (refer to the full manual for specific instructions). Ensure adequate lighting for solar charging.

5.2 Incorrect Calculations

• Check Input: Verify that the numbers and operations were entered correctly using the D.A.L. display.
• Setélan Mode: Ensure the calculator is in the correct mode (e.g., DEG, RAD, STAT) for your calculation. Press MODÉ to cycle through or select modes.
• Reset: If calculations remain incorrect, a full reset may be necessary. Locate the RESET button (often a small recessed button requiring a thin object like a paperclip) and press it. Note that this will clear all memory and settings.
