5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or abrasive materials.
- Battery Replacement: Replace the battery when the display becomes dim or the device fails to power on. Refer to the 'Battery Installation' section for instructions.
- Stylus Care: Keep the stylus clean and store it in its designated slot to prevent loss or damage. Avoid applying excessive force to the stylus or the writing board.
- Storage: When not in use, fold the device to protect both the calculator keys and the writing board. Store in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
- Device Not Turning On: Ensure the battery is correctly installed and has sufficient charge. Replace the battery if necessary.
- Calculator Display is Dim or Blank: This usually indicates a low battery. Replace the battery.
- Notepad Not Erasing: Press the Clear Button firmly. If it still doesn't clear, the notepad's internal battery (separate from the calculator's main battery) might be low. This typically requires professional service or replacement of the device as this battery is often non-user-replaceable.
- Inaccurate Calculations: Ensure you are using the correct mode (DEG/RAD) for trigonometric functions. Double-check your input.
