2. Започнување

2.1. Инсталација на батерија

The Sharp EL501X2BWH calculator operates on two LR44 batteries (included). To install or replace batteries:

1. Осигурајте се дека калкулаторот е исклучен.
2. Пронајдете го капакот на преградата за батерии на задната страна од калкулаторот.
3. Remove the cover using a small screwdriver.
4. Insert two new LR44 batteries, observing the correct polarity (+/-).
5. Добро заменете го капакот на преградата за батерии.

Забелешка: Секогаш користете нови батерии и одговорно фрлете ги старите батерии.

2.2. Вклучување и исклучување

• За да го вклучите калкулаторот, притиснете го копчето ON/C копче.
• To turn off the calculator, press the 2-ри Ф копче проследено со ИСКЛУЧЕНО копче.

2.3. Прикажи надview

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. Основни операции

3.1. Arithmetic Calculations

Perform basic arithmetic operations using the number keys and the +, -, ×, и ÷ клучеви. Притиснете = за да се прикаже резултатот.

• Exampле: To calculate 15 + 7: Press 1 5 + 7 =. Екранот ќе покаже 22.

3.2. Clear Functions

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

4. Научни функции

The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the 2-ри Ф копче пред саканото функционално копче.

4.1. Trigonometric Functions

Користете гревот, cos, тен for standard trigonometric calculations. Their inverse functions (гревот^-1, cos^-1, тен^-1) are accessed via 2-ри Ф.

The angle unit can be changed using the ДСГ клуч. Притиснете ДСГ repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).

4.2. Logarithmic and Exponential Functions

• Logarithms: Користете дневник (основа 10) и ln (природен логаритам).
• Exponentials: Користете 10^x (достапно преку 2-ри Ф и дневник) и e^x (достапно преку 2-ри Ф и ln).

4.3. Powers and Roots

• Плоштад: Користете x².
• Квадратен корен: Користете √ (достапно преку 2-ри Ф и x²).
• Општа моќност: Користете y^x.
• Reciprocal: Користете 1/x (достапно преку 2-ри Ф и y^x).

4.4. Factorials

Calculate factorials using the n! function (accessed via 2-ри Ф и CPLX).

5. Напредни функции

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 СТАТ. The display will show "STAT".

Користете го 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 2-ри Ф.

5.4. Мемориски функции

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

• M+: Adds the displayed value to the memory.
• КНИ: Stores the displayed value into memory.
• RCL: Recalls the value from memory to the display.

6. Одржување и грижа

6.1. Чистење

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 или внатрешни компоненти.

6.2. Складирање

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 Смена на проблеми

7.1. Чести проблеми

• Калкулаторот не се вклучува: Проверете ја инсталацијата на батериите и осигурајте се дека батериите не се испразнети. Заменете ги батериите доколку е потребно.
• "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/C за да ја отстраните грешката и повторно да ја внесете пресметката.
• Неточни резултати: Verify that the correct mode (DEG/RAD/GRAD, Normal/Stat/Complex) is selected for your calculation. Ensure all previous calculations are cleared using ON/C 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 РЕСЕТИРАЈ 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.
