Audiovox aca240 Manuel D’Utilisation

Note: Because this is a wireless system, the monitor is always watching 
for a video signal. It is possible to receive signals from other cameras. 
Systems such as Security camera's, Baby monitors, and even other Back 
up camera systems can trigger the monitor to briefly turn on. This is 
normal for wireless products. If you find you have too much activation 
due to video signals in your area, use the included Monitor Power wire 
and run it to the rear of the vehicle. Attach it to the same power source 
as the camera, this will insure the monitor will only come on when you 
are in reverse and will eliminate any false signals.
