Setup
1. Unboxing and Initial Inspection
Carefully remove the calculator from its packaging. Verify that all components are present: the 2-in-1 Scientific Calculator and the included stylus pen. Inspect the device for any visible damage.
2. Battery Installation
The calculator comes with a pre-installed CR2025 battery. If the display is dim or the device does not power on, the battery may need to be replaced. Refer to the 'Maintenance' section for battery replacement instructions.

3. Stylus Pen
The stylus pen is stored securely on the side of the device. Gently slide it out for use with the writing tablet. Ensure it is properly reinserted into its slot after use to prevent loss.
Operating Instructions
1. Scientific Calculator Functions
The calculator features a 12-digit, 2-line LCD display. The first line shows the calculation process, and the second line displays the result. It supports over 200 functions, including:
- Basic arithmetic operations (+, -, ×, ÷)
- Percentage (%)
- Trigonometric functions (sin, cos, tan)
- Fractions
- Nth root
- Logarithmic functions (log, ln)
- Power functions (x², xʸ)
- Memory functions (STO, RCL)
To perform a calculation, input the numbers and operators using the keypad. The result will appear on the second line of the display.

2. LCD Writing Tablet Functions
The integrated 6-inch LCD writing tablet allows you to jot down notes, diagrams, or intermediate steps. Use the provided stylus pen to write on the tablet surface.
Clearing the Screen:
To clear the entire screen, press the circular Clear Button located below the writing tablet. This action will erase all content on the LCD screen, allowing for repeated use.

Lock Function:
The writing tablet includes a lock switch, typically located on the side or bottom of the device (refer to Figure 2). Sliding this switch to the 'lock' position will prevent accidental erasure of your notes. To clear the screen, you must first slide the switch to the 'unlock' position.
Maintenance
1. Cleaning
To clean the calculator and writing tablet, use a soft, dry cloth. For stubborn smudges, a slightly damp cloth can be used, but ensure no liquid enters the device. Do not use abrasive cleaners or solvents.
2. Battery Replacement
When the display becomes dim or the calculator/writing tablet stops responding, it may be time to replace the CR2025 battery. Locate the battery compartment on the back of the device (refer to Figure 2). Use a small screwdriver to open the compartment, remove the old battery, and insert a new CR2025 battery with the positive (+) side facing up. Close the compartment securely.
3. Storage
Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. When not in use, ensure the stylus is securely stored in its designated slot.
