There is no need to put the DoC in the instruction manual or indeed issue a copy with every product. The minimum required is that one copy be kept in Europe, available to the authorities on request for 10 years after the last sale, at your company office, your approved representitive of failing that the person who first supplies the product in Europe. If you are going to use the technical construction file route the DoC will need to identify that file, give the name and address of the competent body which issued the report or technical certificate on that file and the date and number of that report or certificate. It should also state which if any EMC standards the product conforms to, the name and address of the manufacturer and, if different, the name and address of the person accepting liability for conformance and signing the DoC. Although not required a copy shipped with every item may avoid administative delays if the authorities were to question compliance. Nick Rouse
