2. Setup
2.1. Sors tal-Enerġija
The Sharp EL-520TG calculator is battery-powered. Ensure fresh batteries are installed for reliable operation. Refer to the battery compartment on the back of the unit for battery type and installation instructions.
2.2. L-Ewwel Tixgħil
Agħfas il- ON/Ċ key to power on the calculator. The display should show '0' or a previous calculation result. If the display is blank or dim, replace the batteries.

3. Istruzzjonijiet Operattivi
3.1. Operazzjonijiet Bażiċi
- Qawwa ON/OFF: Agħfas ON/Ċ biex tixgħel. Agħfas It-2 F imbagħad OFF li titfi.
- Dħul tan-Numru: Use the numeric keys (0-9) and the decimal point key (.) to enter numbers.
- Operazzjonijiet Aritmetiċi: Użu +, -, ×, ÷ għaż-żieda, it-tnaqqis, il-multiplikazzjoni, u d-diviżjoni. Agħfas = biex tesegwixxi.
- Clear Entry: Agħfas ON/Ċ to clear the current entry.
- Ħassar: Uża l- DEL key to delete the last entered digit.
3.2. Funzjonijiet
The EL-520TG features 419 functions, accessible directly or via the It-2 F key for secondary functions printed above the keys.
- Direct Algebraic Logic (D.A.L.): Input calculations as they are written, following standard mathematical order of operations.
- Funzjonijiet Trigonometriċi: Użu dnub, cos, tan for sine, cosine, and tangent. Use It-2 F imbagħad sin⁻¹, koż⁻¹, tan⁻¹ for inverse trigonometric functions.
- Funzjonijiet Logaritmiċi: Użu log for common logarithm (base 10) and ln for natural logarithm (base e).
- Funzjonijiet tal-memorja: The calculator has 9 memory registers. Use STO to store a value and RCL to recall a stored value.
- Funzjonijiet Statistiċi: Access statistical modes via MODALITÀ. Calculate standard deviation and other statistical values.
- Funzjonijiet tal-Qawwa u l-Għerq: Użu x² for square, √ for square root, and yˣ for general powers.
3.3. Modi tal-Wiri
Adjust the display format using the SET UP menu.
- WISSI: Specifies the number of decimal places.
- SCI: Displays results in scientific notation.
- ENG: Displays results in engineering notation.
- DEG/RAD/GRAD: Selects the angle unit (degrees, radians, or gradians).
4. Manutenzjoni
4.1. Tindif
Wipe the calculator's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing jew wiri.
4.2. Sostituzzjoni tal-batterija
When the display becomes dim or calculations are erratic, it is time to replace the batteries. Refer to the battery compartment cover for the correct battery type and polarity. Ensure the calculator is turned off before replacing batteries.
4.3. Ħażna
Store the calculator in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective case to prevent scratches and damage to the keys and display.

5 Issolvi l-problemi
- Wiri Vojt jew Mudlama: Check battery installation. Replace batteries if necessary.
- Riżultati Skorretti: Verify the input values and the selected mode (e.g., DEG/RAD). Ensure all previous calculations are cleared.
- Kalkulatur mhux qed jirrispondi: Ipprova agħfas il- RESET button (usually a small button on the back, requiring a thin object like a paperclip to press). This will clear all memory and settings.
- Messaġġi ta' Żball: Consult the full product manual for specific error code meanings. Common errors include 'ERROR' for mathematical impossibilities (e.g., division by zero) or 'OVERFLOW' for results exceeding the calculator's capacity.
