1. Nastavení

1.1 Zdroj napájení

The Casio FX-260 Solar II calculator is primarily solar-powered. It operates efficiently in well-lit environments. No batteries are required for normal operation under sufficient light.

1.2 Počáteční zapnutí

To turn on the calculator, ensure it is exposed to adequate light and press the ON button. The display should show "0". If the display remains blank, ensure sufficient light is available.

1.3 Display Adjustment

The display contrast is fixed. Ensure the calculator is viewed at a comfortable angle under appropriate lighting conditions for optimal readability.

2. Návod k obsluze

This section details the basic and advanced operations of your calculator.

2.1 Základní aritmetické operace

Zadejte čísla pomocí numerické klávesnice. Použijte +, -, X (násobení) a ÷ (division) keys for basic calculations. Press = pro zobrazení výsledku.

• Exampten: To calculate 5 + 3, press 5 + 3 =Výsledek bude 8.

2.2 Vědecké funkce

Many keys have secondary functions, accessed by pressing the POSUN key first, then the desired function key. Secondary functions are typically printed above the keys.

• Goniometrické funkce: Použití hřích, cos, opálení pro sinus, kosinus a tangens. Použijte POSUN pak hřích^-1, cos^-1, opálení^-1 pro inverzní trigonometrické funkce.
• Logaritmické funkce: Použití log pro běžný logaritmus (základ 10) a ln for natural logarithm (base e). Use POSUN pak 10^x or e^x for their inverse functions.
• Mocnina a odmocninové funkce: Použití x² pro umocnění, POSUN pak √ for square root. Use x³ for cubing, POSUN pak ³√ for cube root. Use x^y for arbitrary powers.

2.3 Fraction Calculations

The calculator supports fraction input and calculations.

• Entering Fractions: Použijte ab/c klíč. Napřample, to enter 1/2, press 1 ab/c 2. To enter a mixed number like 1 2/3, press 1 ab/c 2 ab/c 3.
• Converting Fractions to Decimals: After a fraction result, press d/c to convert to decimal. Press again to convert back.

2.4 Funkce paměti

The calculator includes memory functions to store and recall values.

• Store to Memory: To store a displayed value, press POSUN pak X→M.
• Recall from Memory: To recall the stored value, press MR.
• Memory Plus/Minus: Použití M+ to add the displayed value to memory, and M- to subtract it.
• Vymazat paměť: Stiskněte POSUN pak VAK (Clear All Memory).

2.5 Angle Units (DEG/RAD/GRAD)

The calculator can operate in Degree (DEG), Radian (RAD), or Gradian (GRAD) modes for trigonometric calculations.

• Změna režimu: Stiskněte tlačítko MODE key repeatedly to cycle through DEG, RAD, and GRAD. The current mode is indicated on the display.

2.6 Clearing Entries and All Clear

• Volný vstup (C): Stiskněte C to clear the last entered number or operation.
• Vše vymazat (AC): Stiskněte AC to clear all entries, operations, and reset the calculator to its initial state (except memory).

3. Údržba

3.1 Čištění

To clean the calculator, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the casing nebo vnitřních součástí.

3.2 Skladování

Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Avoid placing heavy objects on top of the calculator.

3.3 Péče o solární panely

Ensure the solar panel is kept clean and unobstructed to maintain optimal power generation. Avoid covering the solar panel during use.

4. Řešení problémů

• Displej je prázdný nebo tmavý:

  Ensure the calculator is exposed to sufficient light. The FX-260 Solar II is solar-powered and requires adequate illumination to function. Move the calculator to a brighter area.
• Nesprávné výsledky výpočtu:

  Check the current angle unit mode (DEG, RAD, GRAD) if performing trigonometric calculations. Press MODE to cycle through modes. Ensure all previous operations are cleared by pressing AC before starting a new calculation. Verify correct input of numbers and operations.

• Calculator freezes or becomes unresponsive:

  In rare cases, strong static electricity or other abnormal conditions may cause the calculator to malfunction. Press the AC button to reset the calculator. If the issue persists, move the calculator to a different environment.
