This product is certified to meet the requirements of the European Union (EU)
Electromagnetic Compatibility (EMC) Directive (89/336/EEC). Because the permanent
magnets attached to the loudspeaker drivers produce magnetic fields, it is
recommended that the product not be positioned in very close proximity to computer
monitors or television sets.
