Feature Content Level (upgrade functions)
Along with software options, significant further improvements

All upgrade functions are available to you without
surcharge when you receive a new machine.
Upgrade functions are identified in the manual as FCL n. The n
signifies the serial number of the development status.
You can purchase a code number in order to permanently enable
the FCL functions. For more information, contact your machine tool
