Yes, that isn't 'stand-by' (see below about clocks, door bells, etc.). However, there are some weird definitions of 'stand-by' about. >Did anyone ever received any clarifications from EU on this subject? The CLC/TC59X JWG has asked for many clarifications, but none have yet been received (or hadn't, last week). >how is one suppose to determine what is appropriate or not? By thinking logically about it? A clock, a door bell supply and an antenna masthead amplifier are examples of products where 'always on' is functionally necessary. Obviously, there are others. So is it functionally necessary for your product to be 'always on'? If so, you do not need a switch at all, as long as the mains plug acts as a disconnection device. Furthermore, it is not mandatory to provide a 'stand-by' mode. If it is not functionally necessary to have a 'stand-by' mode, fit a proper mains on-off switch on the front of the product. That way, you meet the 'off-mode' power restriction with no argument. -- OOO - Own Opinions Only. Try www.jmwa.demon.co.uk and www.isce.org.uk Things can always get better.
