If a Trimble Field IQ system looses GPS signal it give a message that section control is disabled and sections must be controlled manually.  Last night dad turned the FMX on while still in the shed and got the message but just ignored it.  When he got to the field the sprayer would only work on manual section control.  He had to exit the field and reload it before it would work on automatic.  Is there a way to re-enable section control once GPS is available without reloading the field?
