Are you sure about that? I mean I know for anything you are gonna consume yes, for safety, warnings instructions, sure, but this is quite a reach. Yes, I've seen those stickers for microwave front panel and suff like that and obviously a french keyboard is a must, but you may be right, when strictly applied... Now we must have a bit of common sense... No one is confused if you see "ON" on a switch. That said, I don't dislike this, I find on this amp it works. But if it really had to be done systematically I could see many designers and manufacturers pulling their hairs, especially for tiny portable products.
