4. CERTIFICATION
4.01
FCC Compliance: The HRU-612 List 2 has
been tested and found to comply with the
limits for Class A. digital devices pursuant to Part 15
of the FCC rules. These limits are designed to
provide reasonable protection against harmful
interference when the equipment is operated in a
commercial environment. This equipment
generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance
with the instruction manual, may cause harmful
interference to radio communications. Operation of
this equipment in a residential area is likely to cause
harmful interference in which case the user will be
required to correct the interference at his own
expense.
4.02
UL Recognized: The HRU-612 List 2 is a UL
Recognized component. Use normal
caution when installing or modifying telephone lines.
Dangerous voltages may be present. It is also
considered imprudent to install telephone wiring
during a lightning storm. Always disconnect all
telephone lines and power connections from wall
outlets before servicing or disassembling this
equipment.
4.03
CSA Certification: The HRU-612 List 2 has
been tested and found to comply with CSA
Standard C22.2-950 with telecommunication
features.
