FCC INFORMATION  
Part 68 is a Federal regulation which requires equipment to be  
tested and registered with the FCC prior to its connection to the  
network. This equipment complies with Part 68 of FCC rules. On the  
bottom of the telephone is a label that contains, among other  
information, the FCC Registration Number and the Ringer  
Equivalence Number (REN) for this equipment. You must, upon  
request, provide this information to your telephone company.  
The Ringer Equivalence Number, which is used to determine the  
number of devices you may connect to your phone line, indicates  
the amount of power that your telephone draws from the  
telephone company line during ringing. If you have more than one  
telephone (or other terminal device) connected to the telephone  
company line, you should total the ringer equivalence numbers  
(REN s), and be sure that the total is not more than five. Your  
telephones may not ring if the total is more than five. Also, in some  
rural locations, your telephone may not ring if the REN total is more  
than three.  
RESTRICTIONS You must not connect your telephone to coin-  
operated lines or party lines.  
INSTALLATION This model telephone must be connected to the  
telephone company lines through a modular jack. The required  
USOC for the modular jack is RJ11C for desk mounting and RJ11W  
for wall mounting. The USOC number is printed on the label on the  
bottom of your telephone.  
HEARING-AID COMPATIBILITY The handset on your telephone  
will work with magnetically- coupled hearing aids. You can use a  
hearing aid equipped with a T (Telephone) switch.  
IN CASE OF TROUBLE If your telephone should cause problems  
on the telephone line, the telephone company can temporarily  
disconnect your service. The telephone company must then notify  
and allow you to correct the problem. The telephone company may  
from time to time change its lines or equipment. They must notify  
you if planned changes will affect your telephone service, to allow  
you to take steps to prevent interruptions.  
Part 15 regulates the electromagnetic energy emitted by  
equipment to minimize interference to radio, television, and other  
wireless devices. This telephone complies with Part 15 of the FCC  
Rules. In the unlikely event that interference occurs, move the  
telephone and/or radio, television, etc. to increase the separation  
distance.
