TH4 Operation
Video System Status
How do I know the DVR is working properly?
Vehicle Operators should check that the DVR status light turns
solid green approximately two minutes after vehicle ignition
is on. Any deviations (flashing green, yellow, or red) should be
reported to a supervisor.
If your system is equipped with the optional
Event/Diagnostic Button
(left image), or the
RGY Indicator
(right image), colored
lights provide status details:
