I bought the remote control in order to manage our entire system. This includes a Panasonic TV, Silvercrest PVR, a Sony AV receiver and a Toshiba DVD player. Setting up the remote control is very simple and the step by step interrogation facilitates a work. Unfortunately, our Panasonic TV made trouble, because he took too long until he could process the next signal after switching on. Here came the support of Logitech into play. You have to understand that you have to create an account for the Harmony with Logitech wherever stored the current configuration. I have described the problem and receive an email after a short time that I should join and upgrade your Harmony to your PC. Unfortunately, a few attempts were necessary, but the communication and also the competence of the Logitech employees is unprecedented. Finally finally has the support solved the problem and now I have a remote control that lets nothing to be desired.
