Questions and answers
why is my ten-tech 61839 digital inspection camera not work even with new batteries
If your CEN-TECH 61839 digital inspection camera is not working even with new batteries, consider the following possible reasons:
1. Battery Installation – Ensure the batteries are correctly installed with the proper polarity.
2. Battery Type – The camera runs on four AA batteries; using low-quality batteries may result in insufficient power. Try high-quality or lithium batteries for better performance.
3. Power Connection – Check for corrosion or dirt on the battery contacts and clean them if necessary.
4. Device Malfunction – If the camera still does not turn on, there may be an internal issue requiring professional servicing.
If none of these steps resolve the issue, the manufacturer recommends repairs only by certified technicians.
