C.1 FCC Requirements
1. The Federal Communications Commission (FCC) has established
rules that permit this device to be directly connected to the telephone
network. Standardized jacks are used for these connections. 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 repair has been
made. If this is not done, the telephone company may temporarily
disconnect service.
3. The telephone company may make changes in its technical operations
and procedures. If such changes affect the compatibility or use of this
device, the telephone company is required to give adequate notice of
the changes.
4. If the telephone company requests information on what equipment is
connected to their lines, inform them of:
a. The telephone number this unit connected to
b. The ringer equivalence (REN) number
c. The USOC jack required
d. The FCC registration number
Items b and d are indicated on the label. The REN is used to determine
how many devices can be connected to your telephone line. In most areas,
the sum of RENs of all devices on any one line should not exceed five (5).
If too many devices are attached, they may not ring properly.
