Important Service Information
RoHS (2002/95/EC) Requirements – Applied to all countries require RoHS.
The RoHS (Restriction of Hazardous Substance in Electrical and Electronic Equipment Directive) is a
legal requirement by EU (European Union) for the global electronics industry which sold in EU and
some counties also require this requirement. Any electrical and electronics products launched in
the market after June 2006 should meet this RoHS requirements. Products launched in the market
before June 2006 are not required to compliant with RoHS parts. If the original parts are not RoHS
complaints, the replacement parts can be non ROHS complaints, but if the original parts are RoHS
compliant, the replacement parts MUST be RoHS complaints.
If the product service or maintenance require replacing any parts, please confirming the RoHS
requirement before replace them.
