2. راه اندازی

2.1 نصب باتری

The HP 50g requires four AAA batteries for primary power and one CR2032 coin cell battery for memory backup. It is recommended to install fresh batteries upon first use.

1. محفظه باتری را در پشت ماشین حساب پیدا کنید.
2. درپوش محفظه را باز کنید.
3. چهار باتری AAA را وارد کنید و از قطبیت صحیح (+/-) اطمینان حاصل کنید.
4. Locate the CR2032 coin cell slot, typically near the AAA compartment. Insert the CR2032 battery with the positive side facing up.
5. درپوش محفظه باتری را محکم ببندید.

Note: The use of rechargeable AAA batteries is not recommended by the manufacturer due to lower capacity and shorter low-battery warning times. However, if used, ensure they are fully charged.

2.2 نصب کارت SD

The HP 50g features an SD card slot for expanded memory and data backup. Only standard SD cards (up to 2 GB) are compatible; SDHC cards are not supported.

Figure 2.1: Inserting an SD card into the HP 50g calculator.

1. Locate the SD card slot on the side or bottom of the calculator.
2. Insert a compatible SD card into the slot until it clicks into place.
3. It is recommended to format the SD card to FAT16 using the calculator's utility for optimal compatibility. Refer to the advanced user's guide for formatting instructions.

2.3 Initial Settings and Connectivity

To optimize the calculator's responsiveness and functionality, adjust the KEYTIME parameter and explore connectivity options.

• KEYTIME Adjustment: To prevent issues with rapidly entered repeating numbers, set the KEYTIME parameter. Press [ALPHA] [ALPHA]، سپس وارد شوید 1138 (یا 500 for a faster response). Press the کلید پیکان سمت راست (representing '->'), then type KEYTIMEو فشار دهید [وارد].
• اتصال USB: Use the provided USB cable to connect the HP 50g to a computer. Install the HP connectivity software (Conn4X) and the latest USB drivers from the HP website to enable data transfer and backup.
• Infrared (IrDA) Transfer: The calculator supports infrared data transfer for communication with other compatible devices.

• Directory Management: Organize your work by creating directories (folders) for different subjects or projects. Avoid saving all files in the HOME directory.
• سفارشی کردن تنظیمات: استفاده کنید حالت منو و پرچم ها to customize display, input, and calculation settings according to your preferences.

3. دستورالعمل های عملیاتی

3.1 Data Entry Modes

The HP 50g offers three primary data entry modes:

• RPN (Reverse Polish Notation): An efficient entry method where operators follow their operands.
• Algebraic: Standard mathematical expression entry.
• Textbook: Displays expressions in a natural, textbook-like format.

You can switch between these modes via the calculator's settings menu.

۴.۳ رسم نمودار توابع

The HP 50g supports a wide range of graphing capabilities:

• 2-D Plotting: Function, polar, and parametric plots.
• 3-D Plotting: Visualize three-dimensional functions.
• Differential Equation Plots: Graph solutions to differential equations.
• Bar Plots: For statistical data representation.

3.3 Using the Intelligent Editor

The intelligent editor allows for manipulation of expressions and objects:

• Sub-expression Evaluation: Isolate and evaluate parts of an expression.
• Cut, Copy, Paste: Standard editing functions for objects and text.

3.4 Key Functions and Libraries

Familiarize yourself with the calculator's keyboard and available libraries:

• طرح بندی صفحه کلید: Many functions are directly accessible. Note that some functions, such as Greek letters, angle symbols, and factorial (!), are not explicitly labeled but are accessible via shift keys or menus.
• APPS Key: را فشار دهید APPS key to access a menu of applications, including the equation writer, matrix writer, math menu, equation library, and constants library.
• PURGE Function: To manage memory and prevent clutter, learn how to use the پاکسازی function to delete variables. This function is typically found within a sub-menu.

4. تعمیر و نگهداری

4.1 تعویض باتری

Regularly check battery levels. Replace AAA batteries when the low-battery warning appears. The CR2032 backup battery should be replaced periodically to ensure memory retention.

• When replacing AAA batteries, it is advisable to connect the calculator to a powered USB port to maintain power and prevent data loss during the change.

4.2 پشتیبان گیری از داده ها

Regularly back up your calculator's data to prevent loss of equations, programs, and settings. This can be done via:

• کارت SD: کپی کنید files and directories to an installed SD card. It is recommended to have at least two SD cards for redundancy.
• کامپیوتر: Use the HP connectivity software (Conn4X) and a USB cable to transfer data to your computer. This allows for comprehensive backups and easy restoration to the same or a new calculator.

4.3 تمیز کردن

برای تمیز کردن ماشین حساب، از یک پارچه نرم و خشک استفاده کنید. برای لکه‌های سرسخت، کمی ...amp می‌توان از پارچه‌ای آغشته به صابون ملایم استفاده کرد و مطمئن شد که هیچ مایعی وارد منافذ نمی‌شود. از پاک‌کننده‌ها یا حلال‌های ساینده خودداری کنید.

5 عیب یابی

5.1 مسائل رایج

• Rapid Key Entry Not Registering: If numbers entered quickly (e.g., '111') only register once, adjust the KEYTIME parameter as described in Section 2.3.
• از دست دادن داده‌ها: If the calculator loses power or needs a reset, data may be lost. This emphasizes the importance of regular backups to an SD card or computer.
• Calculator Freezes/Unresponsive: Try performing a soft reset. If the issue persists, a hard reset may be necessary (refer to the advanced user's guide for instructions, as this may clear all data).

5.2 به روز رسانی سیستم عامل

The HP 50g features a user-upgradeable system BIOS. Regularly check the official HP website for the latest firmware updates, drivers, and connectivity software to ensure optimal performance and access to new features or bug fixes.
