Nastavení

Instalace baterie

Your OSALO Scientific Calculator comes with an LR44 battery pre-installed. The calculator also utilizes solar power for extended battery life and operation in well-lit environments.

1. Ujistěte se, že je kalkulačka VYPNUTÁ.
2. Vyhledejte přihrádku na baterie na zadní straně kalkulačky.
3. Pomocí malého šroubováku otevřete kryt přihrádky na baterie.
4. If replacing, remove the old LR44 battery.
5. Vložte novou baterii LR44 kladným pólem (+) nahoru.
6. Nasaďte kryt prostoru pro baterie a zajistěte jej šroubem.

Note: The solar panel assists in powering the calculator in sufficient light, reducing reliance on the battery.

• Tlačítko ZAPNUTO: Press to turn the calculator on.
• Tlačítko VYP: Stiskněte POSUN pak AC to turn the calculator off.
• Klíč AC: Clears all calculations and returns to the initial display.
• DEL Key: Deletes the last entered character.
• Klávesa SHIFT: Activates the secondary functions (indicated in yellow above the keys).
• ALPHA Key: Activates the alpha functions (indicated in red above the keys).
• MODE/SETUP Key: Changes the calculator's mode (e.g., COMP, STAT, TABLE) or settings.

Základní operace

Enter numbers and operations as you would write them. Press = aby se dosáhlo výsledku.

• Sčítání, odčítání, násobení, dělení: Použijte +, -, ×, ÷ klíče.
• zlomky: Použijte ab/c key to input fractions. For mixed numbers, input integer, then ab/c, then numerator, then ab/c, then denominator.
• Síly a kořeny: Použití x² pro čtverec, SHIFT x² for square root, x³ for cube, SHIFT x³ for cube root, and x^■ for custom powers.

Written Display and Natural Input/Output

The calculator features a 2-line display that shows expressions as they are written in textbooks, making complex calculations easier to understand and verify.
