Reverting to factory default settings
This message appears after you update the control box firmware. All the settings in
the control box are reset to the default values.
Try one of the following actions:
l To restore the settings file for your machine, use the procedure in 3.3.1
Machine settings.
l Ask your site supervisor to configure the system for use on your machine. Save
the new settings in a settings file.
Some of the required system devices are not responding
The system uses a CAN bus to pass information between its components (for
example, to a slope sensor). In this situation, some of the components are not
responding. You cannot use the system until all the devices respond.
Try one of the following actions:
l Check the cables.
l To check which devices are not responding, use the procedure in 7.3 Running
system diagnostics.
If problems persist, contact your dealer.
Some of the required system devices have old firmware versions
To use the coordinate systems and coordinate adjustments supported by the GCS900
Grade Control System v12.70, the system must use MS9x2 GNSS receiver
firmware v4.89 or later.
Contact your site supervisor.
Some settings are missing or invalid, and will be reset to factory defaults
On start-up, or after restoring display or machine settings files, some of the settings
on the control box are missing or invalid. These will be set to the default values.
Try one of the following actions:
l To restore the settings file for your machine, use the procedure in 3.3.1
Machine settings or 3.3.5 Display settings.
l Ask your site supervisor to configure the system for use on your machine. Save
the new settings in a settings file.
