Sover, the CE logo is not only for Electro-Magnetic Compatibility. About everything that is sold in the European Union, from teddy bears to cameras, has to wear that stamp. Depending on the products, requirements are different (EMC, safety, robustness...). Note that it does NOT mean that the article has been officially tested and found to be compliant with the relevant requirements, as the logo is put the the manufacturer. Instead, it is rather a declaration of conformity from the latter. Hope this helps, Nicolas.
