THE FOLLOWING STATEMENT IS REQUIRED BY THE FCC
.
This equipment generates and uses 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 and
television reception. It has been type tested and found to comply with the
limits for a Class-B 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 in a
residential installation.
However, there is no guarantee that 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 off and on, the user is encouraged to try to correct the
interference by one or more of the following measures: reorient the
receiving antenna; relocate the computer with respect to the receiver;
move the computer away from the receiver; plug the computer into a
different outlet so that computer and receiver are on different branch
circuits.
If necessary, the user should consult the dealer or an experienced
radio/television technician for additional suggestions. The user may find
the following booklet prepared by the Federal Communications
Commission helpful: “How to Identify and Resolve Radio-TV Interference
Problems.” This booklet is available from the U.S. Government Printing
Office, Washington, DC 20402; Stock No. 004-000-00345-4.
If a digital communicator is connected to a telephone line, do not notify
the telephone company. It is no longer necessary to call the telephone
company to notify it of the registration and ringer equivalence numbers of
any telephone instrument being connected to the public switched
telephone network. The telephone company will call and request this
information if a need arises in the future.
RINGER EQUIVALENCE NUMBER
The FCC registration label, found on the printed-circuit board and on the
bottom of your telephone sets, includes the ringer equivalence number
(REN). This is a representation of the electrical load that will be applied
to your telephone line. This system has a ringer equivalence of zero.
Therefore, it does not affect the load of the telephone company central
office equipment when your telephones ring. The telephone line
servicing your premises will not operate properly if the total ringer load
exceeds the capability of the central office equipment. That is, if too
many ringers are connected to the line, there may be insufficient energy
to ring your telephones. If the ringer load is excessive, you may also
have difficulty dialing telephone numbers.
If you want to know the total REN allowed for your telephone line, you
may call your telephone company. However, as a rule of thumb, a total
REN of five (5) should permit normal operation of your telephone sets
and equipment. To determine the total ringer load, list the REN of each
of your telephone sets or devices connected to your telephone line. Add
these numbers; the result is the total REN for your line. If this number
exceeds 5, you may want to consult your telephone company to
determine whether or not proper operation of your equipment is possible.
RIGHTS OF THE TELEPHONE COMPANY
If your equipment causes harm to the telephone network, the telephone
company may discontinue your service temporarily. If possible, they will
notify you in advance. But if advance notice is not practical, you will be
notified as soon as possible. You will be given the opportunity to correct
the situation and you will be informed of your right to file a complaint with
the FCC.
Your telephone company may make changes in its facilities, equipment,
operations or procedures that could affect the proper function of your
communicator. If they do, you will be notified in advance to give you an
opportunity to maintain uninterrupted service.
