If necessary, you should consult your dealer or an experienced radio/television technician for additional sug-
gestions. You may find helpful the following booklet prepared by the Federal Communications Commission: 
How to Identify and Resolve Radio-Television Interference Problems. This booklet is available from the Super-
intendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication num-
ber 004-000-00345-4.

Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations 
restricting certain chemical substances.
European Union Restriction of Hazardous Substances (RoHS)
A new law, the European Union Restriction of Hazardous Substances (RoHS) directive, will restrict the pres-
ence of chemical substances, including Lead (Pb), in electronic products effective July 2006. The directive's 
requirements have not been finalized. This drive is manufactured with components and materials that are 
expected to comply with the RoHS directive when the directive takes effect.

Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to 
light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM 
B845. However, this accelerated testing cannot duplicate every potential application environment. Users 
should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive 
chemicals as electronic drive component reliability can be affected by the installation environment. The silver, 
copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chlo-
ride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components 
should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or 
exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulca-
nized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any 
electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.
