5. Maintenance
5.1 Cleaning the Probe and Lens
After each use, especially in dirty or wet environments, gently wipe the camera probe and lens with a soft, damp cloth. For stubborn dirt, use a small amount of mild soap and water, then wipe dry. Do not use abrasive cleaners or solvents.
5.2 Water Resistance
The camera probe is IP67 waterproof, meaning it can be submerged in water up to 1 meter deep for over 1 hour. However, the main display unit is not waterproof. Avoid exposing the main unit to water or excessive moisture.

6. Troubleshooting
- Device does not power on: Ensure the battery is fully charged. Connect the device to a power source and try again.
- No image on screen: Check if the probe cable is securely connected to the main unit.
