IMPORTANT: The use of these procedures could represent a risk (e.g. deletion of application), therefore it is highly recommended that they are performed by qualified experts.

The system functions are speficic procedures that allow the user to perform various operations, e.g. the configuration/calibration of peripherals, data and application save/restore on/from removable mass memory, deletion of the application and management of the mass memories.

All the system functions are listed below.
DEVICE indicates an external storage media. MMC / SD or USB for hardware that they have the port.
