NOTE
 On some vehicles, the reversing light only works when the
ignition is switched on. In this case, you must switch on the
ignition in order to identify the positive and earth wires.
 You can set a switch-off time for the front system if you are
unable to provide a speedometer signal for the front sensor
control electronics (neither a digital connection via the CAN
bus nor an analogue connection from the speedometer) (see
chapter “Programming the system” on page 37 and fig. i,
parameter 1).
 You can connect the control electronics for the rear sensors
directly to the continuous operating voltage or to the positive
cable for the ignition (fig. d) if you are unable to provide a
reversing signal for the rear sensor control electronics (e.g.
+12 V contact voltage from the reversing light). This is only an
option if you use the CAN bus connection to the control unit,
and the vehicle CAN bus provides the reversing signal (see
vehicle-specific product overview on the WAECO homepage
“http://www.dometic-waeco.de/wps900”).
 A reversing signal is not provided via CAN bus on all vehicles
which allow a CAN bus connection.
