10.6 Resetting the settings
i
The instructions differentiate between the internal factory set-
tings and the device configuration.
The factory settings contain the basic configuration of the de-
vice hardware and cannot be changed.
The configuration file (*.SET) contains the individual device
configuration. You can change, save and load the individual
settings.
Reset to the factory settings
You can now reset the device to its factory settings. This deletes the con-
figuration. You must then either load a configuration file or perform the
configuration manually.
Perform the following work steps:
1.
Working in the main menu, navigate to System > Service > Device.
2.
Press “factory settings”.
3.
Confirm with “Yes”.
4
The configuration will be deleted. You must proceed with the follow-
ing section.
ü
All factory default settings will be reset.
Reset the configuration
The device configuration will be saved in *.SET files. A factory-set config-
uration file with standard settings is already present. You can change
these or save your personal configuration in new files.
Recommendation:
Leave the factory-set configuration file unchanged
and save your personal configuration in a new file. Given problems with
the configuration, this enables you to return to a functioning configuration
quickly.
Perform the following work steps:
1.
Working in the main menu, navigate to System > Settings > Configu-
ration.
2.
Select an existing configuration file.
