Configuració
The Casio FX-260 Solar II Scientific Calculator is primarily solar-powered. It does not require battery installation under normal lighting conditions. For optimal performance, ensure the solar panel located above the display is exposed to sufficient light.
- Ús inicial: Upon first use, or after prolonged storage in darkness, expose the calculator to light for a few minutes to activate.
- Encès: Premeu el botó ON botó per engegar la calculadora.
- Apagar: The calculator features an automatic power-off function to conserve energy. To manually turn off, press MAJÚS aleshores OFF (which is typically the AC botó).
Imatge: Primer pla view of the calculator's display area. The display shows numerical output and indicators such as "SHIFT", "MK DEG", and "SCI SD", which denote the current mode and settings of the calculator.
Instruccions de funcionament
The FX-260 Solar II offers 144 built-in mathematical functions. Below are general guidelines for common operations.
Operacions aritmètiques bàsiques
- Suma, resta, multiplicació, divisió: Introdueix números i utilitza els +, -, ×, ÷ claus. Premeu = pel resultat.
- Esborrar entrada/Esborrar tot: Premeu AC to clear the current entry or calculation. Pressing AC twice may clear all memory.
- Retrocés: Utilitza el DEL key to delete the last entered digit.
Funcions científiques
Many scientific functions are accessed directly or by using the MAJÚS clau.
- Funcions trigonomètriques (sin, cos, tan): Enter the angle value, then press the corresponding function key. Ensure the correct angle mode (DEG, RAD, GRA) is selected using the MODE clau.
- Inverse Trigonometric Functions (sin-1, cos-1, bronzejat-1): Premeu MAJÚS, then the respective trigonometric function key.
- Logarithms (log, ln): Utilitza el registre or ln claus.
- Powers and Roots (x², √, xy, 3√): These functions are available directly or via the MAJÚS clau.
- Fraccions: Utilitza el d/c or ab/c keys for fraction input and conversion.
Funcions de memòria
- Store to Memory (M+): To add a value to memory, enter the value and press M+.
- Recall from Memory (MR): Premeu MR to recall the stored value.
- Esborra la memòria: Premeu MAJÚS aleshores MC (often combined with MR or M+).

Manteniment
- Neteja: Feu servir un drap suau i sec per netejar la calculadora. No utilitzeu productes de neteja abrasius ni dissolvents.
- Emmagatzematge: When not in use, store the calculator in its provided slide-on hard case to protect it from dust, scratches, and impact. Avoid storing in extreme temperatures or direct sunlight for extended periods.
- Panell solar: Keep the solar panel clean and unobstructed to ensure continuous power supply.

Resolució de problemes
- La pantalla està en blanc o té poca llum: Ensure the solar panel is exposed to sufficient light. If the issue persists, the internal backup battery (if present in your model) might be depleted.
- Calculator is unresponsive: Proveu de prémer AC button. If still unresponsive, expose it to bright light for a few minutes.
- Resultats incorrectes: Check the angle mode (DEG, RAD, GRA) for trigonometric calculations. Verify input values and function usage.
- Missatges d'error: Refer to the specific error code (if displayed) in the full Casio FX-260 Solar II manual for detailed explanations. Common errors include "Math Error" for invalid operations or "Stack Error" for complex calculations exceeding capacity.
