EMI
FCC
- This equipment generates, uses, and can radiate radio frequency energy,
and if not installed and used in accordance with the instruction manual, may
cause interference to radio communications. It has been tested and found to
comply with the limits for a Class A computing device pursuant with Part 15 of
the FCC Rules, which are designed to provide reasonable protection against
such interference when operated in a commercial environment. Operation of
this equipment in a residential area is likely to cause interference, in which case
the user at his own expense will be required to take whatever measures may be
required to correct the interference. These tests were conducted with shielded
communications cables with metal connector hoods; the use of unshielded
cables may void this compliance.
