TROUBLE AND SOLUTION
1. No picture after powering on the device
. Check the power supply if connected properly
. Check all the cables and monitors if connected properly
2. Interference appears on the picture
.
May be caused by the PSU AC ripples
. Check the monitors and peripheral equipments used
3. The background color of the picture changes continuously
. The color roll may be caused by the electromagnetic field of a fluorescent
lamp
. Reduce the number of fluorescent lamps or increase the distance between
the camera and the fluorescent lamps in order to improve the quality of
the picture
4. Too much smear appears on the picture
.
The PSU voltage is unstable
.
The cables are not connected properly or the impedance is high
For prevention against fire and electric shock. Do not ex-
pose the unit rain
into water too long time directly.
