7. Maintenance

Cleaning: Gently wipe the monitor screen and the probe with a soft, dry cloth. For stubborn dirt on the probe, use a slightly damp cloth and ensure it is completely dry before storage. Do not use abrasive cleaners or solvents.
Storage: Store the borescope in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
Battery Care: For optimal battery life, charge the device regularly and avoid fully discharging it for extended periods. If storing for a long time, charge it to about 50% every few months.
Software Updates: Check the manufacturer's website periodically for any available firmware updates.

8. Troubleshooting

Problem	Possible Cause	Solution
Device does not power on.	Low battery.	Charge the device fully.
No image on screen.	Probe cable not securely connected.	Ensure the probe cable is firmly connected to the monitor unit.
Image is blurry or dark.	Insufficient lighting; dirty camera lens; incorrect focus.	Adjust LED brightness. Clean the camera lens. Ensure the object is within the 45-70mm depth of field.
Cannot record photos/videos.	MicroSD card full or not inserted correctly; card error.	Check MicroSD card insertion. Delete unnecessary files or replace the card. Format the card if necessary (this will erase all data).
Articulation is stiff or unresponsive.	Mechanical obstruction; debris in articulation mechanism.	Carefully inspect the probe tip for any obstructions. Do not force articulation. Contact customer support if the issue persists.
