Before any LCOS update, be sure to backup your current device configuration. Devices featuring the "Firmsafe" function have the option of an initial "test mode" firmware upload. The new firmware is activated permanently only if the device has been accessed with a log-in or for configuration purposes before the pre-set time period has expired. Otherwise, the device switches back to its former version.

Similarly, even those customers with older devices continue to benefit from regular free software updates.
