HOW TO RESET THE DVM-500ULTRA SYSTEM
1.
Remove power from the Interface (I/O) Box for 30-60 seconds by removing the (2) 7.5 Amp fuses from
the side of the small, black I/O Box located in the vehicle (location will vary). The I/O Box, DVM, and
the Camera(s) will reset automatically.
2.
Re-insert both 7.5 Amp fuses into the I/O Box and then power up the system by using the MARK
button, or by turning the vehicle’s ignition switch to the ON position (if the DVM was ordered with the
Ignition Power Up option).
