About Screen Blanking
The CV41 supports screen blanking. When motion is detected, a screen blanking box or
switch turns off the computer screen to avoid unnecessary driver distractions. Once the
vehicle is stationary, the screen turns back on. To enable screen blanking on your com-
puter, you must use one of the following:
• Screen blanking box
• Switch
Honeywell recommends that you use the screen blanking box to enable screen blank-
ing on the CV41. If your vehicle lacks an electrical signal that detects vehicle motion or
your vehicle voltage is not supported by the screen blanking box, use a switch to enable
screen blanking.
You can install the switch in a variety of ways, but Honeywell recommends you install a
switch that closes when the user presses the accelerator pedal on a vehicle.
Honeywell does not sell a switch for screen blanking, but you can purchase a screen
blanking box from Honeywell. For more information, contact your local Honeywell rep-
resentative.
