and sockets #1 or #2 (power, using the red probe) on the end of the cable. If the voltage is
zero, there may be a problem with the cable. If the voltage is at least 10.5 volts, the

If the Display Unit screen turns completely white after powering up the system, the battery
does not have enough voltage to completely power the system. Recharge or replace the
battery
13.2 System Communications
If the battery is OK and the Display Unit turns on, but the GPR sensor does not scan, there may
be a communication failure between the Display Unit and the GPR sensor. If an error occurs,
an error message will appear. Power Off the system and disconnect the battery.
Make sure the display cable is not damaged, all pins are straight, and there is no dirt or debris in
the connector. Ensure that the cable connections are tightly secured. Sometimes vibrations
cause the cable connections to slightly loosen and break contact leading to errors.
Disconnecting the cable and reconnecting it may provide a better contact and solve the
problem. Plug in the battery, turn on the system and try scanning again.
