Hi, it is a question if you freely can choose between Class A and B if you have a product intended for use in purely domestic environment.
As my company's products (units for compressing/decompressing of TV and broadcast signals) mainly are used on broadcast sites it can be discussed if the most relevant Class is A or B. We go for class B, but like John accept Class A, at least until we can improve the product and fulfil Class B. Never heard any complaints from customers for having the Class A warning in the manual. > Venlig hilsen/Best regards > > Niels Hougaard > EMC Engineer, B.Sc.E.E > BarcoNet A/S > Tel +45 39 17 08 47 > Fax +45 39 17 00 10 > Mailto:[email protected] > http://www.barconet.com > > > > -----Original Message----- > From: John Juhasz [SMTP:[email protected]] > Sent: 1. oktober 2001 20:28 > To: '[email protected]'; [email protected] > Subject: RE: Class A ITE > > > Richard, > Interesting question. > While my company's products are technically Class A (by type of product, > usage, etc.), my approach is to get Class B ( I take the Class A if I have > a problem fixing the rare failure on-site so I can at least ship > the product). > I go for the Class B for the reasons you mention.
