Monitor has no display. Cable connecting to
monitor is
disconnected or
damaged. Remove top nine screws securing the front panel
and open. Inspect display cable for cuts or other
damage. If cable is damaged, call Ag Leader
Technology and send the monitor in for repair.
An external device,
such as a GPS
receiver or datalogger
is improperly
connected to monitor. Disconnect external devices and turn the monitor
ON. If the monitor screen turns on correctly, make
sure that he correct cable is used to connect the
external device to the monitor. See “Using a GPS
Receiver” or “Logging Map Data to a Datalogger”
in the Operation Section.
One of the PF3000
sensor cables has a
bad connection Disconnect the PF3000 cables from the
distribution cable, one at a time, leaving the power
cable connected. After disconnecting each cable,
look at the display and see whether it has turned
on.
No GPS Signal. NOTE:
“D” or “G” not
appearing on the top right
hand corner of PF3000

a signal after turning on the monitor.
Inspect the cable from the GPS receiver to the
antenna for damage and proper connection.

he GPS receiver to
the monitor is
incorrect. If a cable designed for the PF3000 was not
provided with the GPS receiver cable, obtain a
GPS null modem cable from Ag Leader

null modem cable from a local store because it
may be wired incorrectly and could damage the
monitor or reset the memory in the GPS
receiver.
