<p>The VMS 7000 series units are triggered by a 12 volt signal on
the reversing sense wire.</p>
<p>Does the screen turn to black when you select reverse?</p>
<p>If not, check this 12 volt wire, the wire coming out of the VMS
unit should have a label that says "BacK", it may be a singular
brown wire.<br>
If the screen does show a black screen then you are not receiving a
signal from the camera, you need to confirm if the camera is
working and check the video cable.</p>
<p>Regards,<br>
VMS support.</p></div>Tech Support 9
