FCC Requirements
This equipment complies with Part 68 of the FCC Rules. On the base unit of this equipment is a
label that contains, among other information, the FCC Registration Number and the Ringer
Equivalence Number (REN) for this equipment.
IF REQUESTED, THIS INFORMATION MUST BE GIVEN TO THE TELEPHONE

The REN is useful to determine the quantity of the devices you may connect to your telephone
line and still have all of those devices ring when your telephone number is called. In most, but not
all areas, the sum of the RENs of all devices connected to one line should not exceed five (5.0).
To be certain of the number of devices you may connect to your line, as determined by the total
RENs, you should contact your local telephone company to determine the maximum REN for
your calling area.
If your equipment causes harm to the telephone network, the telephone company may discontinue
your service temporarily. If possible, they will notify you in advance. But if advance notice isn’t
practical, you will be notified as soon as possible. You will be informed of your right to file a
complaint with the FCC.
Your telephone company may make changes in its facilities, equipment, operations, or
procedures that could affect the proper functioning of your equipment. If they do, you will be
notified in advance to give you an opportunity to maintain uninterrupted telephone service.
If you experience trouble with this telephone equipment, please contact the Address and Phone
number listed in the warranty card for information on obtaining service or repairs.
The telephone company may ask that you disconnect this equipment from the network until the
problem has been corrected or until you are sure the equipment is not malfunctioning.
