3. Návod k obsluze

3.1. Základní výpočty

To perform basic arithmetic operations, simply input the numbers and operators in sequence. Press = aby se dosáhlo výsledku.

• Přidání: [Number] + [Number] =
• Odčítání: [Number] - [Number] =
• Násobení: [Number] × [Number] =
• Divize: [Number] ÷ [Number] =

3.2. Vědecké funkce

The calculator supports 240 scientific functions. Many functions are accessed by pressing the POSUN key before the desired function key (indicated by text above the key).

• Goniometrické funkce: Použití hřích, cos, opálení. For inverse functions, press POSUN then the respective key (e.g., POSUN + hřích for sin^-1).
• Logaritmické funkce: Použití log (základ 10) a ln (přirozený logaritmus).
• Síly a kořeny: Použití x², x³, √ (square root). For other roots or powers, use POSUN with relevant keys.
• Angle Units: Stiskněte MODE multiple times to cycle through angle units (Degrees, Radians, Gradians).

3.3. Memory Calculations

The calculator includes 9 variable memories (A-F, X, Y, M) for storing and recalling values.

• Obchod: Input a value, then press STO followed by the desired memory key (e.g., A).
• Odvolání: Stiskněte RCL followed by the desired memory key to recall the stored value.
• Memory Plus/Minus: Použití M+ to add the displayed value to memory M, and POSUN + M+ (M-) to subtract.

3.4. Statistical Calculations

Pro vstup do statistického režimu stiskněte MODE and select the STAT option. Follow the on-screen prompts to input data and perform calculations such as standard deviation and regression analysis.

3.5. Nastavení jasu displeje

The calculator features a brightness adjustment function to optimize visibility in different lighting conditions and reduce eye strain.

4.3. Výměna baterie

When the display becomes dim or the calculator functions erratically, it may be time to replace the LR44 battery. Carefully open the battery compartment on the back of the calculator, replace the old battery with a new LR44 battery, ensuring correct polarity, and close the compartment securely.

5. Řešení problémů

• Kalkulačka se nezapne:
  • Ensure there is sufficient light for the solar panel.
  • Check if the LR44 battery needs replacement.
  • Stiskněte tlačítko ON key firmly.
• Displej je tmavý nebo prázdný:
  • Increase ambient light for solar power.
  • Vyměňte baterii LR44.
  • Adjust display brightness settings (refer to section 3.5).
• Nesprávné výsledky výpočtu:
  • Verify the input values and operators.
  • Check the current calculation mode (e.g., DEG/RAD/GRA for angles).
  • Clear all memory and reset the calculator by pressing POSUN + CLR (Režim 3).
• Klávesy nereagují:
  • Ujistěte se, že se pod klávesami nenacházejí žádné nečistoty.
  • Clean the calculator surface.
