3. Operasyon Enstriksyon
3.1. Operasyon debaz yo
- Pouvwa ON/OFF: Peze ON/C pou limen. Peze 2yèm F lè sa a OFF pou etenn.
- Antre nimewo: Use the numeric keys (0-9) and the decimal point key (.) to enter numbers.
- Operasyon aritmetik: Sèvi ak +, -, ×, ÷ for addition, subtraction, multiplication, and division. Press = pou egzekite.
- Antre klè: Peze ON/C pou efase antre aktyèl la.
- Efase: Sèvi ak la DEL key to delete the last entered digit.
3.2. Fonksyon
The EL-520TG features 419 functions, accessible directly or via the 2yèm 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.
- Fonksyon trigonometrik: Sèvi ak peche, kos, tan pou sinis, kosinis, ak tanjant. Sèvi ak 2yèm F lè sa a sin⁻¹, kos⁻¹, tan⁻¹ for inverse trigonometric functions.
- Fonksyon Logaritmik: Sèvi ak boutèy demi lit pou logaritm komen (baz 10) ak ln pou logaritm natirèl (baz e).
- Fonksyon memwa: The calculator has 9 memory registers. Use STO to store a value and RCL pou raple yon valè ki estoke.
- Fonksyon estatistik: Access statistical modes via MÒD. Calculate standard deviation and other statistical values.
- Fonksyon Puisans ak Rasin: Sèvi ak x² for square, √ pou rasin kare, epi yˣ for general powers.
3.3. Display Modes
Adjust the display format using the METE meni.
- RANJE: Espesifye kantite plas desimal yo.
- SCI: Displays results in scientific notation.
- ENG: Displays results in engineering notation.
- DEG/RAD/GRAD: Selects the angle unit (degrees, radians, or gradians).
4. Antretyen
4.1. Netwayaj
Wipe the calculator's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing oswa ekspozisyon.
4.2. Ranplasman batri
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. Depo
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.

NAN. Depanaj
- Ekspozisyon vid oswa fèb: Tcheke enstalasyon pil yo. Ranplase pil yo si sa nesesè.
- Rezilta ki pa kòrèk: Verify the input values and the selected mode (e.g., DEG/RAD). Ensure all previous calculations are cleared.
- Kalkilatè a pa reponn: Eseye peze la 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.
- Mesaj erè: 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.
