Customer-Provided
Telephone
Equipment FCC regulations and telephone company procedures prohibit connection of
customer-provided equipment to telephone company-provided coin service (central
office-implemented systems). Connection to party lines is subject to state tariffs.
Occasionally, the telephone company may make changes in their equipment,
operations, or procedures. If these changes affect your equipment or service, the
telephone company will provide written notice so you can make the necessary
changes to maintain uninterrupted service.
Contact your telephone company if you have any questions about your telephone
line.
In some circumstances, the telephone company may ask you for information about
your equipment that is connected to the telephone line. Within the United States (at
the request of the telephone company), you should provide your equipment’s FCC
registration number. This number is located on the unit’s label.

Regulations
Concerning
Electromagnetic
Radiation
The Federal Communications Commission (FCC) of the United States of America
and the Industry and Science Canada (ISC), have published regulations which
govern the allowable limits of emanation of radio frequency energy of computing
devices and associated peripherals. These regulations are concerned with
interference to radio communications, such as radio and television. The regulations
require equipment for use in the United States or Canada to be labeled and to be
accompanied by the following notice:
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against interference when 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 interference to radio communications.
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus set out in the radio interference regulations of the ISC.
