Q1: Why the PDA can’t open the camera, and the display fails?
A1: There are two reasons for this problem：
1) Please close the camera software in the task process
The reason for this problem is that the camera process is blocked in the background and the PDA cannot open the camera app again
2) If you still have a fault after switching off the camera, the camera connection cable is faulty, please contact our technical team.
