l Troubleshooting
Question 1: Computer can’t detect the View Cam
Solving Method: Check if computer’s OS (Operating System),
BIOS, USB Port or installation errors occurs.
Steps: Windows 95 doesn’t support USB port. You have to
update your OS to Windows 98 or above to support USB port and
ensure BIOS Setup and USB settings are available. If the problem
still occurs, please try connecting the USB ViewCam to your
machine via another USB socket.
Question 2： My video image is too dim or too light.
Solving Method: Adjust the brightness and contrast background.
Steps: Because the ViewCam can be easily affected by light,
therefore, we suggested proceeding from usage environment and
screen object such as increasing object brightness or moving light
source.
