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 mag-

netically-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 com-

pany must then notify and allow you to correct the problem.
