Nessuna configurazione necessaria Musica. It works with my westinghouse tv works better than the remote inbox with tv same model which worked on occasion, Musica. My first remote died because of the batteries that shipped with the tv they corroded and ate apart the remote before i had to change the battery. Even changing the battery didn’t fix it very bad batteries with the remotes this product fixed. My issue westinghouse, could improve their product line if they ditched the generic batteries and went with proven brands Music. But the tv used with no remote and ordered this one 5 stars because it is the oem remote controls all of the functions of the tv and was delivered promptly in new condition.
