Labelling is an interesting topic, though also a source of great frustration it seems. In response to a couple of the comments below......
>>> As a consumer, why do I need to know the meaning of EMC and Radio markings? >>> As a consumer, I only need to know efficiency ratings at the time I choose the appliance/equipment. I wonder how many people understand the Alert Symbol (!) of the R&TTE Directive. When you see the Alert Symbol on your radio product (such as on most mobile phones, wireless internet, UWB devices, etc.), it is often there to alert the user that there is a restriction of use for the product. The user then knows (???) to go to the user manual and read the restrictions of their device before they power it on. .....right? :-) >>> Such ratings need not be a permanent part of the equipment, but can be on a disposable tag. There is no post-purchase need for such data. One word..... "e-bay" :-) Do we all buy our products new, from the original supplier? Just to stir the pot, Michael.

As a consumer, why do I need to know the meaning of EMC and Radio markings? As a consumer, I only need to know efficiency ratings at the time I choose the appliance/equipment. Such ratings need not be a permanent part of the equipment, but can be on a disposable tag. There is no post-purchase need for such data. As a consumer, I simply plug the equipment into the wall outlet. The equipment is pre-configured for voltage and is provided with the proper plug for my house. I don't need to know voltage, current, watts, or frequency ratings of the equipment. If a house circuit-breaker trips when I turn on my equipment, I may need to know the current or power rating of my equipment in order to balance the load on the circuit. So, who are the rating markings for? The certifiers and regulators. The ratings could just as well be in the accompanying documents.
