• Cable Care: Avoid sharp bends or kinks in the semi-rigid cable. Coil it loosely for storage to prevent damage.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the device regularly, especially before long periods of storage.
• Storage: Store the endoscope in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

• No Image on Screen: Ensure the device is powered on and fully charged. Check the cable connection to the main unit. If the issue persists, try resetting the device using the reset pinhole (refer to Figure 7).
• Poor Image Quality: Adjust the LED light brightness. Clean the camera lens. Ensure the focal range is appropriate (front camera: 3-8cm / 1.2-3.1in; side camera: 2-6cm / 0.8-2.4in).
• Device Not Charging: Verify the USB cable is securely connected to both the device and the power source. Try a different USB port or power adapter.
• Cannot Save Photos/Videos: Check if the 32GB TF card is properly inserted. If the card is full, delete old files or format the card via the device's menu (this will erase all data).
