2. Configurare
2.1 Despachetarea
Upon opening the package, ensure the following items are present:
- Sharp EL-506TSBBW Scientific Calculator
- Carcasă rigidă de protecție
- Manual de instrucțiuni (acest document)
- 1 baterie LR44 (preinstalată)
Sursa de alimentare 2.2
The EL-506TSBBW calculator utilizes a hybrid power system, combining solar power with a pre-installed LR44 battery.
- Energie solara: The calculator will primarily use solar power when sufficient light is available. Ensure the solar panel, located above the display, is exposed to light during use.
- Putere baterie: The LR44 battery provides power in low-light conditions or when solar power is insufficient. The battery is pre-installed and typically does not require immediate replacement.
Pentru a porni calculatorul ON, apăsați tasta ON/C key. To turn the calculator OFF, apăsați A doua linie de atac urmată de OFF/C. The calculator will also automatically power off after a period of inactivity to conserve battery life.
3. Instrucțiuni de utilizare
The Sharp EL-506TSBBW features a 12-digit, 2-line LCD display and 470 functions across 6 modes.
3.1 Display and Basic Input
The 2-line display shows the calculation entry on the upper line and the result on the lower line simultaneously. The Direct Algebraic Logic (D.A.L.) system allows for inputting equations exactly as they are written.
- Entering Numbers: Folosiți tastele numerice (0-9) și tasta pentru virgulă zecimală (.).
- Operații de bază: Utilizare +, -, ×, ÷ pentru adunare, scădere, înmulțire și împărțire.
- Egal cu: Presa = pentru a executa calculul.
- Ștergere intrare/Ștergere totală: Presa ON/C once to clear the current entry. Press it twice to clear all calculations and settings.
- Tasta de pornire: The ACASĂ key allows users to return to the initial calculation screen, clearing any previously entered data or settings.

4. Întreținere
4.1 Curățare
Pentru a menține aspectul și funcționalitatea calculatorului:
- Wipe the calculator's surface with a soft, dry cloth.
- Pentru murdăria persistentă, dreaptă ușorampClătiți cârpa cu apă. Nu utilizați substanțe chimice dure, solvenți sau produse de curățare abrazive.
- Avoid getting moisture into the calculator's openings.
4.2 Înlocuirea bateriei
The calculator uses one LR44 button cell battery. When the display becomes dim or erratic in low light, it may be time to replace the battery.
- Asigurați-vă că calculatorul este oprit.
- Localizați compartimentul bateriilor pe spatele calculatorului.
- Carefully open the compartment using a small screwdriver if necessary.
