  • Page 19: Acoustics Emissions

    Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this pro- cess is the use of the absolute threshold of hearing. Seagate uses the lower limit for the threshold curve* to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards.

  • Page 20: Reliability

    EN 55024. 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.

  • Page 21: Fcc Verification

    Seagate has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursu- ant to Subpart J, Part 15 of the FCC rules.

  • Page 22: Environmental Protection

    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%.
