When the meter is turned on, the LCD screen can display this error message if the GPS is not already on or if it's settings are not compatible with the Field Scout meters. The GPS unit should be set for:

NMEA 0183 input/output messages
GGA data string
4800 baud rate
Timing - 1 second
8 data bits
No parity
1 stop bit

Some newer GPS units require 2 way RS-232 communication.  This was addressed in firmware v5.0.  Meters with firmware version 5 will also need a black GPS/DGPS cable that is marked v. 5 (item 2950CV5).

Another reason for this message is if the meter is searching unsuccessfully for the differential correction factor for DGPS. In this case, open the software and, in Meter Settings, uncheck the option requiring the DGPS correction factor when acquiring GPS data. Also, check that the GPS unit is turned on AND has located all the satellites. See
