Why? Ever use one? If the power goes out, the system is off. Press the Off button and it changes its state/"knowledge' of the equipment's state and anything with toggling power commands will turn on, just like they would with a URC, RTi, etc. Press the button for the activity and then press Help to correct it. The option to that is pressing the activity button again.

Sounds like you haven't used one recently- you would be surprised by the new models.
