SMART LOADER
Description.
The Smartloader is a function implemented in the service software of SEES designed L730 series intended to easily replicate the user settings of one TV into another. These settings include (but not restricted to): picture and audio, tuning set-up, language and country selection, PIN, child locked programs… Factory adjustments are not copied as they
are different for every TV.
The Smartloader makes possible the user data to be stored in a memory device connected to the USB terminal of the TV that is used as reference and later load those data into other TVs by using their respective USB terminal.
