REGULATORY INFORMATION
FCC Part 68 Compliance
These telephones are hearing-aid compatible and comply with Part
68 of the Federal Communications Commission (FCC) rules. On the
bottom of the phone is a label that contains, among other
information, the FCC registration number and Ringer Equivalence
Number (REN) for the phone. If requested, this information must be
provided to the telephone company.
Installation
The modular telephone outlet or jack to which the telephone must
be connected is a Universal Service Order Code (USOC) RJ11C or
RJ11W. For modem interface purposes on two-line models, the
connection may be made using a USOC RJ14 type jack. The
telephones are registered to operate in Central Office (CO), private
branch exchange (PABX), key system and Centrex applications. The
phones cannot be used on telephone company-provided coin
service. Connection to Party Line Service is subject to state tariffs.
Ringer Equivalence Number
The REN is used to determine the quantity of devices which may be
connected to the telephone line. Excessive RENs on the telephone
line may result in the devices not ringing in response to an
incoming call. In most, but not all, areas the sum of the RENs should
not exceed 5. To be certain of the number of devices that may be
connected to the line, as determined by the total RENs, contact the
telephone company to determine maximum REN for calling area.
Incidence of Harm
If this equipment causes harm to the telephone network the
telephone company will notify you in advance that temporary
discontinuance of service may be required. If advance notice isn't
practical, the telephone company will notify you as soon as
possible. Also, you will be advised of your right to file a complaint
with the FCC if you believe it is necessary.
Telephone Company Rights
The telephone company may make changes in its communications
facilities, equipment, operations, or procedures that could affect
the operation of the equipment. If this happens, the telephone
company will provide advance notice in order for you to make the
necessary modifications to maintain uninterrupted service.
