1) The DVR will not capture images if the door of the unit is open or unlocked. Close and lock the door,
then turn off the vehicle. After the vehicle has shut down, restart the engine.
2) Shortly after the DVR restarts, image capture can be verified by the keypad display or the green
status light (or combination of green and red status lights).
3) Check the DVR configuration using the keypad. Verify that any DVR camera ports without cameras
connections are disabled in the configuration.

IEW OPERATING NORMALLY BUT STATUS LIGHTS ARE NOT ILLUMINATING
All status lights will be turned off after the shutdown display, when the DVR has shutdown completely.
The shutdown delay is the number of minutes the DVR will continue to run after the vehicle has been
turned off (see section
5.1.4 System Variable Setup Menus ).
The status lights are supplied with 12 or 30 VDC continuous power from the vehicle. Verify that
continuous voltage is present at the status light.
The ground for the status lights is supplied by the DVR connection box. To check the ground output with
a voltage meter, perform the following:
1) Place the positive meter probe onto an unused 12 VDC DVR output on the J9 or J11 terminal block
(Figure 24).
2) Place the negative meter probe into terminal 13 of the J11 terminal block.
3) Use the keypad or Test Kit to enter test mode. Refer to section 4.2 System Testing to test the
outputs.
4) Terminal 13 of the J11 terminal block is the normal operation output. Voltage should be observable
on the meter when the keypad test output menu displays “on” or “off” (see Figures 42 – 45).
Note: Voltage may vary from +5 VDC to +12 VDC, depending on the type of status indicator installed.
5) If voltage is not present, remove any wires that are connected to terminal 13 and repeat steps 1
through 4.
6) Repeat steps 1 through 5 for terminal 15 of the J11 terminal block.
7) If the vehicle power and the DVR’s negative (ground) output are both present at the light, but the
light is not illuminating, it might be necessary to troubleshoot the vehicle wiring or replace the status
light.
