A Category 5 (or better) twisted pair cable must be used to connect the
modules in order to maintain compliance with radio frequency energy emission
regulations and ensure a suitably high level of immunity to electromagnetic
disturbances.
All other interface cables used with this equipment must be shielded in order
to maintain compliance with radio frequency energy emission regulations and
ensure a suitably high level of immunity to electromagnetic disturbances.

European EMC directive 89/336/EEC

This equipment has been tested and found to comply with the limits for
a class A computing device in accordance with the specifications in the
European standard EN55022. These limits are designed to provide reasonable
protection against harmful interference. This equipment generates, uses and

can radiate radio frequency energy and if not installed and
used in accordance with the instructions may cause harmful
interference to radio or television reception. However, there
is no guarantee that harmful interference will not occur
in a particular installation. If this equipment does cause

interference to radio or television reception, which can be determined by turning
the equipment on and off, the user is encouraged to correct the interference
with one or more of the following measures: (a) Reorient or relocate the
receiving antenna. (b) Increase the separation between the equipment and the
receiver. (c) Connect the equipment to an outlet on a circuit different from that
to which the receiver is connected. (d) Consult the supplier or an experienced
radio/TV technician for help.

FCC Compliance Statement (United States)

This equipment generates, uses and can radiate radio frequency energy
and if not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication.
It has been tested and found to comply with the limits for a class A computing
device in accordance with the specifications in Subpart J of part 15 of FCC rules,
which are designed to provide reasonable protection against such interference
when the equipment is operated in a commercial environment. Operation of this
equipment in a residential area may cause interference, in which case the user at
his own expense will be required to take whatever measures may be necessary
to correct the interference. Changes or modifications not expressly approved by
the manufacturer could void the user’s authority to operate the equipment.
