EQUIPMENT APPROVAL INFORMATION
Your telephone equipment is approved for connection to the Public SwitchedTelephone Network and is in compliance with
parts 15 and 68, FCC Rules and Regulations and theTechnical Requirements forTelephoneTerminal Equipment published
by ACTA.
1. Notification to the Local Telephone Company
On the bottom of this equipment is a label indicating, among other information, the US number and Ringer
Equivalence Number (REN) for the equipment.You must, upon request, provide this information to your telephone
company.
The REN is useful in determining the number of devices you may connect to your telephone line and still have all of these
devices ring when your telephone number is called. In most (but not all) areas, the sum of the RENs of all devices connected
to one line should not exceed 5. To be certain of the number of devices you may connect to your line as determined by the REN,
you should contact your local telephone company.
Notes
•This equipment may not be used on coin service provided by the telephone company.
•Party lines are subject to state tariffs, and therefore, you may not be able to use your own telephone equipment if you are
on a party line. Check with your local telephone company.
•Notice must be given to the telephone company upon permanent disconnection of your telephone from your line.
2. Rights of the Telephone Company
Should your equipment cause trouble on your line which may harm the telephone network, the telephone company shall,
where practicable, notify you that temporary discontinuance of service may be required. Where prior notice is not
practicable and the circumstances warrant such action, the telephone company may temporarily discontinue service
immediately. In case of such temporary discontinuance, the telephone company must: (1) promptly notify you of such
temporary discontinuance; (2) afford you the opportunity to correct the situation; and (3) inform you of your right to bring a
complaint to the Commission pursuant to procedures set forth in Subpart E of Part 68, FCC Rules and Regulations.
The telephone company may make changes in its communications facilities, equipment, operations or procedures where
such action is required in the operation of its business and not inconsistent with FCC Rules and Regulations. If these
changes are expected to affect the use or performance of your telephone equipment, the telephone company must give you
adequate notice, in writing, to allow you to maintain uninterrupted service.
INTERFERENCE INFORMATION
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)This device
may not cause harmful interference; and (2)This device must accept any interference received, including interference that
may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules.These limits are designed to provide reasonable protection against harmful interference in a residential
installation.
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 communications. However, there is no guarantee that
interference will not occur in a particular installation.
If this equipment does cause harmful 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 or relocate the receiving antenna (that is, the antenna for radio or television that is “receiving” the
interference).
•Reorient or relocate and increase the separation between the telecommunications equipment and receiving antenna.
•Connect the telecommunications equipment into an outlet on a circuit different from that to which the receiving
antenna is connected.
If these measures do not eliminate the interference, please consult your dealer or an experienced radio/television
technician for additional suggestions. Also, the Federal Communications Commission has prepared a helpful booklet,
“HowTo Identify and Resolve Radio/TV Interference Problems.”This booklet is available from the U.S. Government
Printing Office, Washington, D.C. 20402. Please specify stock number 004-000-00345-4 when ordering copies.
