c) Check all 37 sockets at the end of the cable, ensuring that none are blocked with debris.
If so, clean out the debris, reconnect the cable and try powering the Display Unit again.
d) With the cable connected to the LMX Sensor and the battery connected to the system,
check the power from the battery is reaching the Display Unit through the cable by using a
multimeter to measure the voltage between socket #21 (ground, using the black probe)
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
problem may be the Display Unit. Please contact your GPR supplier for further assistance.

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
