About the Screen Blanking Box

The screen blanking box helps improve operator safety and
reduce driver distractions by turning off the computer display
when the vehicle is in motion.

The screen blanking box monitors the connection of a vehicle
motion sensing circuit. When motion is detected, the blanking
box opens the connection, which turns off the computer
display. When motion is no longer detected, the blanking box
connects the output feeds and the display turns on again.

Caution: The screen blanking box should only be
installed by trained service personnel.

Before You Begin

Before you install the screen blanking box, you need to
supply power to the vehicle mount computer. For information
about the power supplies supported by your computer, see
the computer user manual.
