Configuració

1. Instal·lació de la bateria

The calculator operates using both solar power and a single LR44 alkaline battery, which is included. The battery provides power when lighting conditions are insufficient for solar operation.

1. Assegureu-vos que la calculadora estigui apagada.
2. Localitza el compartiment de la bateria a la part posterior de la calculadora.
3. Obriu amb cura la tapa del compartiment.
4. Introduïu la pila LR44, respectant la polaritat correcta (+/-).
5. Tanqueu bé la tapa del compartiment de la bateria.

2. Encendre/apagar

• Per engegar la calculadora, premeu la tecla ON/C clau.
• Per apagar la calculadora, premeu 2n F seguit de APAGAT/ENCENDENT. The calculator will also automatically power off after a period of inactivity to conserve battery life.

Instruccions de funcionament

Operacions aritmètiques bàsiques

Perform standard calculations using the numeric keys and operation symbols (+, -, ×, ÷). Premeu = per mostrar el resultat.

Using the 2nd F Key

Many keys have secondary functions printed above them. To access these functions, press the 2n F key (located on the left side of the keypad) followed by the desired function key.

Display Modes (DEG/RAD/GRAD)

The calculator supports degree (DEG), radian (RAD), and gradian (GRAD) angle units. The current mode is indicated on the display. To change the mode, press DRG (often accessed via 2n F) repeatedly until the desired mode is selected.

Multi-Line Playback

Utilitzeu les tecles de fletxa (▲, ▼, ◄, ►) to scroll through previous calculations and edit entries. This feature allows for easy review and correction of complex equations.

Funcions avançades

Funcions científiques

The calculator includes a wide range of scientific functions:

• Funcions trigonomètriques: pecat, cos, bronzejat i les seves funcions inverses (sin⁻¹, cos⁻¹, bronzejat⁻¹).
• Funcions logarítmiques: registre (base 10) i ln (logaritme natural).
• Funcions potència i arrel: x², x³, yˣ, √ (square root), ³√ (cube root).
• Constants: Accés π (pi) and other constants using the appropriate keys.

Complex Number Calculations

The SH-EL520TGGY supports calculations involving complex numbers. Refer to the specific key labeled for complex number entry and operations, typically found near the i or ENG funcions.

Càlculs estadístics

To enter statistical mode, press MODE and select the statistical option. Input data points and use the statistical function keys (e.g., mean, standard deviation) to perform calculations.

Memory Functions (STO/RCL)

Utilitza el STO (Store) key to save a value to memory and the RCL (Recall) key to retrieve a stored value. The calculator typically has multiple memory registers.

Manteniment

Neteja

To clean the calculator, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the display or internal components.

Canvi de bateria

If the display becomes dim or the calculator functions erratically, the LR44 battery may need replacement. Follow the battery installation steps outlined in the "Setup" section. Dispose of used batteries according to local regulations.

Emmagatzematge

Store the calculator in a cool, dry place, away from direct sunlight and extreme temperatures. Always use the protective hard cover to prevent scratches and damage to the keys and display.

Resolució de problemes

• La calculadora no s'encén:
  • Comproveu la instal·lació de la bateria i assegureu-vos de la polaritat correcta.
  • Replace the LR44 battery if it is depleted.
  • Ensure sufficient light for solar panel operation.
• La pantalla està tènue o en blanc:
  • Substitueix la pila LR44.
  • Move to a brighter environment for solar power.
• Resultats de càlcul incorrectes:
  • Verify the input values and operation sequence.
  • Check the current angle mode (DEG/RAD/GRAD).
  • Perform a calculator reset if issues persist.
• To Reset the Calculator:

  Localitza el RESET button (often a small, recessed button requiring a thin object like a paperclip to press). Pressing this button will clear all memory and return the calculator to its default settings. Use this only if other troubleshooting steps fail.
