    Once you have configured the new machine, the system sends updates to the GPS Receiver (if required). A dialog informs you that the GPS Receiver is being configured.

    If the changes are successful, you return to the "Setup Menu - Installation" dialog.

    If the changes are not successful, a dialog informs you that the GPS Receiver configuration was not updated. In order to solve this:

    • Make sure the GPS Receiver is being recognized by the system. In order to do this, check the "Diagnostics" dialog.

    • Send a GPS configuration file by reselecting the current design (if the current design contains a coordinate system).

    • Send a GPS configuration file using the "GPS Receiver Configuration" item on the "Setup Menu".

12. Press the "ESC" key in order to exit the "Setup Menu - Installation" dialog. The changes take effect immediately.
