FCC REQUIREMENTS FOR TELEPHONE-LINE EQUIPMENT
1.
The Federal Communications Commission (FCC) has established rules which permit this
device to be directly connected to the telephone network with standardized jacks. This
equipment should not be used on party lines or coin lines.
2. If this device is malfunctioning, it may also be causing harm to the telephone network;
this device should be disconnected until the source of the problem can be determined and
until the repair has been made. If this is not done, the telephone company may
temporarily disconnect service.
3. If you have problems with your telephone equipment after installing this device,
disconnect this device from the line to see if it is causing the problem. If it is, contact
your supplier or an authorized agent.
4. The telephone company may make changes in its technical operations and procedures. If
any such changes affect the compatibility or use of this device, the telephone company is
required to give adequate notice of the changes.
5.
If the telephone company requests information on what equipment is connected to their
lines, inform them of:
a. The telephone number that this unit is connected to.
b. The ringer equivalence number.
c. The USOC jack required: RJ-11C.
d. The FCC registration number.
Items (b) and (d) can be found on the unit
’ s FCC label. The ringer equivalence
number (REN) is used to determine how many devices can be connected to your
telephone line. In most areas, the sum of the RENs of all devices on any one
line should not exceed five (5.0). If too many devices are attached, they may not
ring properly.
6. In the event of an equipment malfunction, all repairs should be performed by your
supplier or an authorized agent. It is the responsibility of users requiring service to report
the need for service to the supplier or to an authorized agent.
