3. Operacions bàsiques

3.1. Arithmetic Calculations

Perform basic arithmetic operations using the number keys and the +, -, ×, i ÷ claus. Premeu = per mostrar el resultat.

• ExampLI: To calculate 15 + 7: Press 1 5 + 7 =. La pantalla mostrarà 22.

3.2. Clear Functions

• Premeu CE to clear the last entered number or operation.
• Premeu ON/C to clear all entries and reset the calculator to its initial state (except memory).

4. Scientific Functions

The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the 2n F tecla abans de la tecla de funció desitjada.

4.1. Trigonometric Functions

Ús pecat, cos, bronzejat for standard trigonometric calculations. Their inverse functions (pecat^-1, cos^-1, bronzejat^-1) s'hi accedeix a través de 2n F.

The angle unit can be changed using the DRG clau. Premeu DRG repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).

4.2. Logarithmic and Exponential Functions

• Logaritmes: Ús registre (base 10) i ln (logaritme natural).
• Exponentials: Ús 10^x (accessed via 2n F i registre) i e^x (accessed via 2n F i ln).

4.3. Powers and Roots

• Quadrat: Ús x².
• Arrel quadrada: Ús √ (accessed via 2n F i x²).
• Potència general: Ús y^x.
• Reciprocal: Ús 1/x (accessed via 2n F i y^x).

4.4. Factorials

Calculate factorials using the n! funció (a la qual s'accedeix mitjançant 2n F i CPLX).

5. Funcions avançades

5.1. N-Base Calculations (HEX, DEC, BIN, OCT)

The calculator supports calculations in different number bases: hexadecimal (HEX), decimal (DEC), binary (BIN), and octal (OCT). Use the dedicated keys for these operations, typically found above the number keys (e.g., →OCT, →BIN, →DEC, →HEX).

5.2. Complex Number Calculations

To enter and perform calculations with complex numbers, switch to Complex Mode. Press CPLX to activate this mode. The display will show "CPLX".

Refer to the calculator's key markings for specific complex number operations (e.g., real and imaginary part extraction, argument, magnitude).

5.3. Statistics Functions

The calculator supports one-variable statistical calculations. To enter Statistics Mode, press ESTADÍSTICA. The display will show "STAT".

Utilitza el DATA CD key to clear statistical data and the M+ key to input data points. Statistical results (mean, standard deviation, etc.) can be retrieved using specific function keys, often accessed via 2n F.

5.4. Funcions de memòria

The calculator has one independent memory. Use the following keys:

• M+: Adds the displayed value to the memory.
• STO: Stores the displayed value into memory.
• RCL: Recalls the value from memory to the display.

6. Manteniment i cura

6.1. Neteja

To clean the calculator, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator, as this may damage the casing o components interns.

6.2. Emmagatzematge

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

7. Solució De Problemes

7.1. Problemes comuns

• La calculadora no s'encén: Comproveu la instal·lació de les piles i assegureu-vos que no estiguin esgotades. Substituïu les piles si cal.
• "Error" message displayed: This usually indicates an invalid operation (e.g., division by zero, taking the square root of a negative number). Press CE or ON/C to clear the error and re-enter the calculation.
• Resultats incorrectes: Verify that the correct mode (DEG/RAD/GRAD, Normal/Stat/Complex) is selected for your calculation. Ensure all previous calculations are cleared using ON/C before starting a new one.

7.2. Resetting the Calculator

If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the RESET button (a small recessed button, often requiring a thin object like a paperclip to press) on the back or front panel. Pressing this button will clear all memory and settings, returning the calculator to its factory default state.
