FCC INFORMATION
Part 68 is a Federal regulation which requires equipment to be tested and registered with
the FCC prior to its connection to the network. This equipment complies with Part 68 of FCC
rules. On the bottom of the telephone is a label that contains, among other information, the
FCC Registration Number and the Ringer Equivalence Number (REN) for this equipment. You
must, upon request, provide this information to your telephone company.
The Ringer Equivalence Number, which is used to determine the number of devices you
may connect to your phone line, indicates the amount of power that your telephone draws
from the telephone company line during ringing. If you have more than one telephone (or
other terminal device) connected to the telephone company line, you should total the ringer
equivalence numbers (REN s), and be sure that the total is not more than five. Your tele-
phones may not ring if the total is more than five. Also, in some rural locations, your
telephone may not ring if the REN total is more than three.
RESTRICTIONS You must not connect your telephone to coin-operated lines or party lines.
INSTALLATION This model telephone must be connected to the telephone company lines
through a modular jack. The required USOC for the modular jack is RJ11C for desk mounting
and RJ11W for wall mounting. The USOC number is printed on the label on the bottom of your
telephone.
IN CASE OF TROUBLE If your telephone should cause problems on the telephone line, the
telephone company can temporarily disconnect your service. The telephone company must
then notify and allow you to correct the problem.
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 opera-
tion.
Warning: Changes or modifications to this unit not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the equipment.
Note: 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 equip-
ment 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 communica-
tions. 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 recep-
tion, 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.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
•Consult the dealer or an experienced radio TV technician for help.
NOTICE: This equipment meets the applicable Industry Canada Terminal Equipment Technical
Specifications. This is confirmed by the registration number. The abbreviation, IC, before the

Conformity indicating that Industry Canada technical specifications were met. It does not
