3. Ρύθμιση

3.1. Τοποθέτηση μπαταρίας

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.

1. Βεβαιωθείτε ότι η αριθμομηχανή είναι απενεργοποιημένη.
2. Εντοπίστε τη θήκη των μπαταριών στο πίσω μέρος της αριθμομηχανής.
3. Χρησιμοποιήστε ένα μικρό κατσαβίδι για να ανοίξετε το κάλυμμα του διαμερίσματος.
4. Αφαιρέστε την παλιά μπαταρία LR44 και τοποθετήστε μια καινούργια, φροντίζοντας για τη σωστή πολικότητα (+/-).
5. Replace the compartment cover and secure it with the screw.

3.2. Αρχική ενεργοποίηση

Πατήστε το ON/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. Οδηγίες λειτουργίας

4.1. Βασικές Λειτουργίες

Εκτελέστε τυπικούς αριθμητικούς υπολογισμούς χρησιμοποιώντας τα αριθμητικά πλήκτρα και τους τελεστές (+, -, x, ÷). Τύπος = 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. ΓράψτεView Επίδειξη

Το ΓράψτεView 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. Επιστημονικές Λειτουργίες

Access various scientific functions using the dedicated keys and the 2ο Φ key for secondary functions. These include:

• Τριγωνομετρικές συναρτήσεις: sin, cos, tan, and their inverse functions (sin^-1, συν^-1, Έτσι^-1).
• Υπερβολικές Συναρτήσεις: hyp, and their inverse functions.
• Λογαριθμικές και Εκθετικές Συναρτήσεις: log, ln, 10^x, ε^x.
• Λειτουργίες Ισχύος και Ρίζας: x², √, x^y, ^y√x.
• Factorial, Permutations, Combinations: n!, nPr, nCr.
• Σταθερές: Pi (π), EXP.

4.4. Statistical Functions

The calculator supports statistical calculations for 1-variable and 2-variable data. To enter statistical mode, press ΤΡΟΠΟΣ 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. Λειτουργίες μνήμης

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+ και 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 DRG key to cycle through these units or use the ΣΤΗΝΩ 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 ΤΡΟΠΟΣ menu to switch between number systems.
