    A better scrutiny of the data sheet, or even a simple call to the vendor will do.(I don't want to sound rude, but this is what I do).

    This is post no. 2 of the same thread. Hope you... well, nothing. I believe that my reputation in CE is a bit tainted. Lets hope I won't need to prove it here! This is disturbing as it really makes no sense.
