2. This device must accept any interference received, including interference that may cause
undesired operations.

This equipment has been tested and found to comply with the limits for a CLASS B digital
device pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy, and if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.

If this equipment does cause harmful interference to radio/television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver

is connected.

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.

The user is not authorized to repair or modify the equipment.
This equipment may not be used on coin service provided by the telephone company.
