2. Twaqqif u Użu Inizjali

2.1 Sors tal-Enerġija

The EL-531TG-GY calculator operates using both solar power and a single LR44 button cell battery. The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions or when solar power is insufficient. An LR44 battery is included with the calculator.

2.2 Tixgħel/Jitfi

• To turn the calculator ON, agħfas il- ON/Ċ ċavetta.
• To turn the calculator OFF, agħfas il- It-2 F muftieħ segwit mill - OFF key (which is typically the same as ON/Ċ).

2.3 Initial Display Settings

Upon first use or after a reset, the calculator will typically default to certain settings (e.g., DEG for angle units). Refer to Section 3.3 for details on changing mode settings.

3. Istruzzjonijiet Operattivi

3.1 Operazzjonijiet Aritmetiċi Bażiċi

Daħħal in-numri billi tuża t-tastiera numerika. Uża l- +, -, ×, u ÷ keys for addition, subtraction, multiplication, and division, respectively. Press = to obtain the result.

3.2 Funzjonijiet Xjentifiċi

The calculator performs over 273 advanced scientific functions. Many functions are accessed by pressing the It-2 F ċavetta qabel iċ-ċavetta tal-funzjoni mixtieqa.

• Funzjonijiet Trigonometriċi: Użu dnub, cos, tan. Inverse functions (sin⁻¹, koż⁻¹, tan⁻¹) huma aċċessati permezz ta' It-2 F.
• Funzjonijiet Logaritmiċi: Użu log (bażi 10) u ln (logaritmu naturali).
• Powers and Roots: Użu x², √, x³, ³√.
• Frazzjonijiet: Uża l- d/c ċavetta għad-dħul u l-konverżjoni tal-frazzjonijiet.

3.3 Mode Settings (DEG/RAD/GRAD)

To change the angle unit mode (Degrees, Radians, Gradians):

1. Agħfas il- DRG ċavetta.
2. Agħfas ripetutament DRG to cycle through DEG (Degrees), RAD (Radians), and GRAD (Gradians). The current mode is indicated on the display.

3.4 Funzjonijiet tal-Memorja

The calculator includes memory functions for storing and recalling values.

• STO (Ħanut): Agħfas STO followed by a variable key (e.g., A, B) to store the displayed value.
• RCL (Iftifkira): Agħfas RCL followed by the variable key to recall the stored value.
• M+ (Memory Plus): Adds the displayed value to the independent memory.
• M- (Minus Memorja): Subtracts the displayed value from the independent memory.

3.5 Multi-Line Playback

The 2-line display allows for Multi-Line Playback, enabling users to review previous calculations and expressions. Use the directional arrow keys (up/down) to scroll through past entries and results. This feature is useful for checking work or re-using parts of previous calculations.

4. Manutenzjoni

4.1 Tindif

To clean the calculator, wipe the surface gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the display or internal components.

4.2 Sostituzzjoni tal-batterija

The calculator uses one LR44 button cell battery. If the display becomes dim or erratic in low-light conditions, the battery may need replacement. To replace the battery:

1. Kun żgur li l-kalkulatur ikun mitfi.
2. Sib il-kompartiment tal-batterija fuq wara tal-kalkulatur.
3. Iftaħ l-għatu tal-kompartiment bir-reqqa.
4. Neħħi l-batterija LR44 il-qadima u daħħal waħda ġdida, waqt li tiżgura l-polarità korretta (+/-).
5. Agħlaq l-għatu tal-kompartiment tal-batterija sew.

4.3 Ħażna

When not in use, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. The hard cover included with the calculator provides protection from scratches and minor impacts.

5 Issolvi l-problemi

5.1 Kwistjonijiet tal-Wiri

• Wiri Vojt jew Mudlama: Ensure sufficient light for the solar panel. If the issue persists, replace the LR44 battery.
• Wirja Erratika: This may indicate a low battery. Replace the LR44 battery.

5.2 Riżultati Mhux Korretti

• Check Mode Settings: Verify that the angle unit (DEG, RAD, GRAD) is set correctly for trigonometric calculations.
• Żball fl-Input: Review your input using the Multi-Line Playback feature to ensure the expression was entered correctly.
• Memory Contents: If using memory functions, ensure the stored values are correct.

5.3 Il-Kalkulatur Mhux Jirrispondi

If the calculator becomes unresponsive, try performing a reset. Locate the RESET button (often a small recessed button requiring a thin object like a paperclip to press). Pressing this button will clear all memory and return the calculator to its factory default settings.
