7 Safety and Regulatory Agency Compliance

Electromagnetic Compatibility (EMC)

When properly installed with a shielded cabinet, shielded cable and adequate grounding of the SCSI bus and the input power, the tape drive meets the requirements for radiated and conducted emissions as defined by the following standards:

FCC Rules, Part 15, Class B Computing Devices

Canadian Department of Communications, Radio Interference

Regulation for Digital Apparatus, Class B

VDE Vfg 1046/1984, Class B

CISPR Publication 22, 1985, Class B

Radiated Susceptibility

When properly installed with a shielded cabinet, shielded cables, and adequate grounding of the SCSI bus and the input power, the tape drive will continue to operate without error when subjected to electromagnetic energy of severity level 2 (3 volts/meter) as defined by IEC Publication 801-3.
