Remove the micro SD card and insert it into a card reader connected to your computer. Alternatively, connect the main unit via USB cable (if supported) and copy files.

Clean the lens on the camera head with a soft cloth. Ensure the probe tip is not touching the object being inspected. Adjust the focus ring if available.

With new alkaline batteries, you can expect approximately 2 hours of continuous use. Rechargeable batteries may vary.

The BR250 records video without audio. It captures only visual footage.

Avoid bending the probe at sharp angles. The minimum bend radius is about 50 mm to prevent internal damage.
