No surprise with this new model, despite the comment of a user "installation difficult for everyman." I'm no good at that "Mrs. World" and I managed to put it into service. In short, if you do not want to bite your fingers during a storm or power loss "temporary" from your common dear, you made the right choice and also by reading me. PS: If after loading it properly, and you are not able to switch it on: top center, press the small button in the middle. And electricity passes. Thank you that? LOL06
