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.

CDC STATEMENT  
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.  
CERTIFICATION NOTICE FOR EQUIPMENT USED IN CANADA  
The Canadian Department of Communications label identifies certified equipment. This certification means  
that the equipment meets certain telecommunications-network protective, operation, and safety  
requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction.  
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of  
the local telecommunications company. The equipment must also be installed using an acceptable method of  
connection. In some cases, the company’s inside wiring associated with a single-line individual service may be  
extended by means of a certified connector assembly (extension cord). The customer should be aware that  
compliance with the above conditions may not prevent degradation of service in some situations.  
Repairs to certified equipment should be made by an authorized Canadian maintenance facility—in this case,  
your supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions,  
may give the telecommunications company cause to request the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical ground connections of the power utility,  
telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution  
may be particularly important in rural areas.

CAUTION:  
Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority,  
or electrician, as appropriate.  
The LOAD NUMBER (LN) assigned to each terminal device denotes the percentage of the total load to be  
connected to a telephone loop which is used by the device, to prevent overloading. The termination on a  
loop may consist of any combination of devices, subject only to the requirement that the total of the load  
numbers of all the devices does not exceed 100.

adapter is plugged in and  
has power.
