Hard drives that display the CE mark comply with the European Union (E U) re qui rem ent s specified in the Elec-

Seagate uses an independent laboratory to confirm complian ce wit h th e EC di rectives sp ecifi ed in t he pr evious
paragraph. Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply
with the directives when used in the test systems, we cannot guarantee that all systems will comply with the
directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O
cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators
should confirm EMC compliance and provide CE marking for their products.
