Funtzio zientifikoak
The calculator includes 414 pre-programmed functions covering statistics, n-base calculations, logical operators, trigonometry, logarithms, and more. Access these functions using the dedicated keys or by pressing 2nd F followed by the key with the desired secondary function.
- Funtzio trigonometrikoak: bekatua, cos, beltzarana and their inverse functions (accessed via 2nd F).
- Logarithmic Functions: erregistroa, ln.
- Power and Root Functions: x², √, xʸ.
- Estatistikak: Enter STAT mode via MODUA to perform statistical calculations.
- N-Base Calculations: Perform calculations in binary, octal, decimal, and hexadecimal bases.
Memoria Funtzioak
The calculator features 4 shortcut memory buttons (D1, D2, D3, D4) for quick access to frequently used functions or constants. Additionally, standard memory functions (M+, M-, RCL, STO) are available.
- STO (Store): Stores a value into a memory variable.
- RCL (Recall): Recalls a value from a memory variable.
- M+ / M-: Adds to or subtracts from the independent memory.

Mantentzea
Garbiketa
To clean the calculator, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the casing edo barne osagaiak.
Biltegiratzea
When not in use for extended periods, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its protective cover to prevent scratches and damage.
Bateria zaintzea
If the calculator will not be used for a very long time, it is advisable to remove the LR44 battery to prevent potential leakage and damage to the device.
Arazoak konpontzea
Bistaratzeko arazoak
- Pantaila hutsa: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- Pantaila ahula: This may indicate a low battery. Replace the LR44 battery.
Incorrect Calculations
- Emaitza okerrak: Verify the input method (D.A.L.) and ensure all values are entered correctly. Check if the calculator is in the correct mode (e.g., DEG/RAD for trigonometric functions, STAT mode for statistics).
- Errore-mezua: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
Kalkulagailua berrezarri
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the small reset button (often on the back or side, requiring a thin object like a paperclip to press) or perform a soft reset via the KONFIAZIOA menu. Note that resetting may clear all memory and settings.
