3. Impostazione
3.1. Installazione della batteria
The calculator operates on a Twin Power system, utilizing both solar power and a single LR44 button cell battery. The battery is typically pre-installed. If the display becomes dim or unresponsive in low light, the battery may need replacement.
- Assicurarsi che la calcolatrice sia SPENTA.
- Individuare il vano batterie sul retro della calcolatrice.
- Utilizzare un piccolo cacciavite per aprire il coperchio del vano.
- Rimuovere la vecchia batteria LR44 e inserirne una nuova, assicurandosi della corretta polarità (+/-).
- Replace the compartment cover and secure it with the screw.
3.2. Accensione iniziale
Premere il tasto ACCESO/C button to turn on the calculator. The display will show the initial screen. If the display is blank, ensure sufficient light for solar power or check the battery.

4. Istruzioni per l'uso
4.1. Operazioni di base
Perform standard arithmetic calculations using the number keys and operators (+, -, x, ÷). Premere = to get the result. The calculator uses Direct Algebraic Input Logic (D.A.L.), allowing you to input equations in a natural order.
4.2. ScrivereView Display
La scritturaView display allows you to enter and view mathematical expressions and symbols as they appear in textbooks. This 96 x 32 dot matrix display supports up to 4 lines of content. Use the cursor keys to navigate and edit expressions.
4.3. Funzioni scientifiche
Access various scientific functions using the dedicated keys and the 2° piano key for secondary functions. These include:
- Funzioni trigonometriche: sin, cos, tan, and their inverse functions (sin-1, così-1, così-1).
- Funzioni iperboliche: hyp, and their inverse functions.
- Funzioni logaritmiche ed esponenziali: logaritmo, ln, 10x, ex.
- Funzioni potenza e radice: x2, √, xy, y√x.
- Factorial, Permutations, Combinations: n!, nPr, nCr.
- Costanti: Pi (π), EXP.
4.4. Statistical Functions
The calculator supports statistical calculations for 1-variable and 2-variable data. To enter statistical mode, press MODALITÀ and select the appropriate statistical option. Functions include:
- Mean value (x̄, ȳ)
- Standard deviation (σx, σy, sx, sy)
- Sum of values (Σx, Σy, Σx2, Σy2, Σxy)
- Regression analysis (linear, quadratic, exponential, etc.)
4.5. Funzioni di memoria
The calculator has 9 independent memories (A-F, X, Y, M) to store and recall values. Use the STO key to store a value and the RCL key to recall a stored value. M+ E M- are used to add or subtract values from the independent memory M.
4.6. Angle Units
The calculator supports three angle units: Degrees (DEG), Radians (RAD), and Gradians (GRAD). Press the DOGANA key to cycle through these units or use the IMPOSTARE menu to select the desired unit.
4.7. Number Systems
Perform calculations and conversions in different number bases: Decimal (DEC), Hexadecimal (HEX), Octal (OCT), Binary (BIN), and Pentary (PEN). Use the dedicated keys or the MODALITÀ menu to switch between number systems.
4.8. Shortcut Keys (D1-D4)
The four shortcut keys (D1, D2, D3, D4) can be programmed to quickly access frequently used functions. Refer to the calculator's on-screen setup menu for instructions on how to assign functions to these keys.

5. Manutenzione
5.1. Pulizia
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 o componenti interni.
5.2. Sostituzione della batteria
Refer to Section 3.1 for instructions on replacing the LR44 battery. Always use a fresh, high-quality LR44 battery for optimal performance.
5.3. Conservazione
When not in use, store the calculator in its protective hard case to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.
