information, the FCC registration number and ringer equivalence number (REN) for this equipment. If requested, this
information must be provided to the telephone company.
The FCC requires that you connect your telephone to the telephone network through a modular telephone outlet or jack,
which must comply with FCC part 68 rules. The modular telephone outlet or jack to which your 2750 telephone must be
connected is a USOC RJ11C or RJ14C. The Facility Interface codes (FIC) for your 2750 telephone is 02LS2 which is a 2-
wire, Local Switched Access, Loop-start.
The Ringer Equivalence Number (REN) is used to determine the quantity of devices which may be connected to the
telephone line. The REN for your 2750 telephone is 0.2. Excessive RENs on the telephone line may result in the devices not
ringing in response to an incoming call. In most areas, the sum of the RENs should not exceed five (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 the maximum REN for the calling area.
If the 2750 telephone 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. The telephone company may make changes in its 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 in order to maintain uninterrupted service.
