If a connection error occurs then displays. To diagnose a connection error:
• Check that the External Radio settings (Parity, Reference Format and Baud
Rate) match these same settings on the external radio and base station.
• Check that the radio (whip) antenna mounted on the GPS antenna on the
vehicle’s cab, has line of sight with the radio and this is not obstructed by
buildings, trees, etc.
• Check the radio (whip) antenna for damage.
• Check that the external radio is turned on, receiving GPS data and has a posi-
tion fix.

TM
Fallback screen the operator can choose to have the system use
the GL1DE
TM
correction source in the event that the External Radio correction
source fails, by selecting the Enable Fallback checkbox.
• Time Limit is the time in minutes that the system will use the GL1DE
TM
correc-
tion source. If the External Radio correction source has not come back online
in this time period, then auto-steer is disabled.
• Drift Limit - if the External Radio correction source comes back online and the
drift from the wayline is less than this value (in the units of the configured
region) then auto-steer remains enabled. However, if the drift from the
wayline is greater than this value, then auto-steer is disabled.
