3. Performing Inspection
Gently insert the 8mm diameter camera cable into the area you wish to inspect. The 1920 x 1080P resolution provides clear images on the 4.3-inch display. The focal distance (FD) is approximately 4cm to 500cm (1.6 to 196.9 inches), allowing for clear viewing of objects within this range. The horizontal viewing angle is 70 degrees.
The camera cable is IP67 waterproof, making it suitable for use in damp or wet conditions, such as inspecting pipes or drains. Avoid prolonged submersion beyond the IP67 rating.

Maintenance
1. Cleaning
- Camera Lens: Gently wipe the camera lens with a soft, dry, lint-free cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying.
- Display Screen: Clean the 4.3-inch display screen with a soft, dry microfiber cloth. Avoid abrasive cleaners.
- Main Unit and Cable: Wipe the main unit and cable with a damp cloth as needed. Ensure the charging port cover is securely closed if cleaning near it.
2. Battery Care
To prolong the life of the built-in 2600mAh lithium battery, avoid fully discharging it frequently. Recharge the device when the battery indicator is low. If storing for extended periods, charge the battery to approximately 50% every few months.
3. Storage
Store the endoscope in a cool, dry place, away from direct sunlight and extreme temperatures. Keep the camera cable neatly coiled to prevent kinks or damage. Ensure all accessories are stored safely to prevent loss.
