1. Kun żgur li l-kalkulatur ikun mitfi.
2. Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-kalkulatur.
3. Remove the cover using a small screwdriver.
4. Insert two new LR44 batteries, observing the correct polarity (+/-).
5. Ibdel l-għatu tal-kompartiment tal-batterija b'mod sikur.

Nota: Always use fresh batteries and dispose of old batteries responsibly.

2.2. Tixgħel u Mitfi

• Biex tixgħel il-kalkulatur, agħfas il-buttuna ON/Ċ buttuna.
• To turn off the calculator, press the It-2 F buttuna segwita mill- OFF buttuna.

2.3. Uri Fuqview

The calculator features a 10-digit, 1-line LCD display. Indicators for various modes (e.g., DEG, RAD, GRAD, CPLX, STAT) will appear on the display to show the current calculator state.

3. Operazzjonijiet Bażiċi

3.1. Arithmetic Calculations

Perform basic arithmetic operations using the number keys and the +, -, ×, u ÷ ċwievet. Agħfas = biex turi r-riżultat.

• Example: To calculate 15 + 7: Press 1 5 + 7 =. Il-wiri se juri 22.

3.2. Clear Functions

• Agħfas CE to clear the last entered number or operation.
• Agħfas ON/Ċ to clear all entries and reset the calculator to its initial state (except memory).

4. Funzjonijiet Xjentifiċi

The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the It-2 F key before the desired function key.

4.1. Trigonometric Functions

Użu dnub, cos, tan for standard trigonometric calculations. Their inverse functions (dnub^-1, cos^-1, tan^-1) are accessed via It-2 F.

The angle unit can be changed using the DRG ċavetta. Agħfas DRG repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).

4.2. Logarithmic and Exponential Functions

• Logarithms: Użu log (bażi 10) u ln (logaritmu naturali).
• Exponentials: Użu 10^x (accessed via It-2 F u log) u e^x (accessed via It-2 F u ln).

4.3. Powers and Roots

• Pjazza: Użu x².
• Għerq Kwadru: Użu √ (accessed via It-2 F u x²).
• Qawwa Ġenerali: Użu y^x.
• Reciprocal: Użu 1/x (accessed via It-2 F u y^x).

4.4. Factorials

Calculate factorials using the n! function (accessed via It-2 F u CPLX).

5. Funzjonijiet Avvanzati

5.1. N-Base Calculations (HEX, DEC, BIN, OCT)

The calculator supports calculations in different number bases: hexadecimal (HEX), decimal (DEC), binary (BIN), and octal (OCT). Use the dedicated keys for these operations, typically found above the number keys (e.g., →OCT, →BIN, →DEC, →HEX).

5.2. Complex Number Calculations

To enter and perform calculations with complex numbers, switch to Complex Mode. Press CPLX to activate this mode. The display will show "CPLX".

Refer to the calculator's key markings for specific complex number operations (e.g., real and imaginary part extraction, argument, magnitude).

5.3. Statistics Functions

The calculator supports one-variable statistical calculations. To enter Statistics Mode, press STAT. The display will show "STAT".

Uża l- DATA CD key to clear statistical data and the M+ key to input data points. Statistical results (mean, standard deviation, etc.) can be retrieved using specific function keys, often accessed via It-2 F.

5.4. Funzjonijiet tal-Memorja

The calculator has one independent memory. Use the following keys:

• M+Iżżid il-valur muri mal-memorja.
• STO: Stores the displayed value into memory.
• RCL: Recalls the value from memory to the display.

6. Manutenzjoni u Kura

6.1. Tindif

To clean the calculator, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator, as this may damage the casing jew komponenti interni.

6.2. Ħażna

When not in use, store the calculator in its protective hardcover to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.

7 Issolvi l-problemi

7.1. Kwistjonijiet Komuni

• Il-kalkulatur ma jixgħelx: Iċċekkja l-installazzjoni tal-batterija u kun żgur li l-batteriji mhumiex eżawriti. Ibdel il-batteriji jekk meħtieġ.
• "Error" message displayed: This usually indicates an invalid operation (e.g., division by zero, taking the square root of a negative number). Press CE or ON/Ċ to clear the error and re-enter the calculation.
• Incorrect results: Verify that the correct mode (DEG/RAD/GRAD, Normal/Stat/Complex) is selected for your calculation. Ensure all previous calculations are cleared using ON/Ċ before starting a new one.

7.2. Resetting the Calculator

If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the RESET button (a small recessed button, often requiring a thin object like a paperclip to press) on the back or front panel. Pressing this button will clear all memory and settings, returning the calculator to its factory default state.
