Xerox 240 参考指南

1. The 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 
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. You will be 
advised of your right to file a complaint with the FCC.

4. If the telephone company requests information on what 

equipment is connected to their lines, inform them of:

A. the telephone number this unit is connected to.

B. the ringer equivalence number.

C. the USOC jack required.

D. the FCC Registration number.

Items ‘B’ and ‘D’ are indicated on the 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 correctly.

or to an authorized agent. Service can be obtained at:
