There is no guarantee that interference shall not occur in a particular installa­tion. If this equipment does cause harmful interference to radio (and) or televi­sion reception, which can be determined by turning the equipment on and off,
and noting any change in said interference, the user is encouraged to try to cor­rect the interference by one or more of the following measures:

which 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

one line should not exceed five (5.0). If too many devices are attached,
they may not ring properly.
