2. شروع به کار

2.1. نصب باتری

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

1. مطمئن شوید که ماشین حساب خاموش است.
2. پوشش محفظه باتری را در پشت ماشین حساب پیدا کنید.
3. Remove the cover using a small screwdriver.
4. Insert two new LR44 batteries, observing the correct polarity (+/-).
5. درپوش محفظه باتری را به طور ایمن تعویض کنید.

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

2.2. روشن و خاموش کردن

• برای روشن کردن ماشین حساب، دکمه ON/C دکمه
• To turn off the calculator, press the دوم اف دکمه و به دنبال آن خاموش دکمه

2.3. نمایش بیش ازview

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. عملیات اساسی

3.1. Arithmetic Calculations

Perform basic arithmetic operations using the number keys and the +, -, ×، و ÷ کلیدها مطبوعات = برای نمایش نتیجه

• Exampدر: برای محاسبه ۱۵ + ۷: فشار دهید 1 5 + 7 =. صفحه نمایش 22 را نشان می دهد.

3.2. Clear Functions

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

۴.۲ توابع علمی

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

4.1. Trigonometric Functions

استفاده کنید گناه, cos, برنزه for standard trigonometric calculations. Their inverse functions (گناه^-1, cos^-1, برنزه^-1) از طریق آنها قابل دسترسی هستند دوم اف.

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

4.2. Logarithmic and Exponential Functions

• لگاریتم‌ها: استفاده کنید ورود به سیستم (پایه ۱۰) و ln (لگاریتم طبیعی).
• Exponentials: استفاده کنید 10^x (دسترسی از طریق دوم اف و ورود به سیستم) و e^x (دسترسی از طریق دوم اف و ln).

4.3. Powers and Roots

• مربع: استفاده کنید x².
• ریشه دوم: استفاده کنید √ (دسترسی از طریق دوم اف و x²).
• قدرت عمومی: استفاده کنید y^x.
• Reciprocal: استفاده کنید 1/x (دسترسی از طریق دوم اف و y^x).

4.4. Factorials

Calculate factorials using the n! تابع (قابل دسترسی از طریق دوم اف و CPLX).

5. توابع پیشرفته

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 آمار. The display will show "STAT".

استفاده کنید سی‌دی داده 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 دوم اف.

۷. عملکردهای حافظه

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

• M+: مقدار نمایش داده شده را به حافظه اضافه می‌کند.
• STO: Stores the displayed value into memory.
• RCL: Recalls the value from memory to the display.

6. نگهداری و مراقبت

6.1. تمیز کردن

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 یا اجزای داخلی.

6.2. ذخیره سازی

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 عیب یابی

۷.۲ مشکلات رایج

• ماشین حساب روشن نمی‌شود: نصب باتری را بررسی کنید و مطمئن شوید که باتری‌ها خالی نشده‌اند. در صورت لزوم باتری‌ها را تعویض کنید.
• "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 to clear the error and re-enter the calculation.
• نتایج نادرست: 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 تنظیم مجدد 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.
