LIKELY SOLUTION
Check input power connections
at the cable leads.
Check for loose wires.
If connected to DC, check input
voltage range of 10.5 – 40V.
If connected to AC, check input
voltage range of 12 – 28V.
Measure the voltage and current
at the Input Power Cable.
The current should be >.02A
and <1.0A.
Determine if wiring polarity at
"Video Connector" terminal
block is correct.
Check the cable and BNC
connector.
If still no video, connect the
camera directly to the monitor.
Check the video signal. If okay,
the problem is with the
interconnections. If still no
video, contact BOSCH Service
Center. See rear page of this
manual for contact information.
