INTERFERENCE INFORMATION: PART 15 OF FCC RULES
Some telephone equipment generates and uses radio frequency energy which if not
properly installed, may cause interference to radio and television reception.
This unit has been tested and found to comply with the limits for a Class B computing
device in accordance with the specifications in Part 15 of the FCC rules. These
specifications are designed to provide reasonable protection against such interference
in a residential installation. However, there is no guarantee that interference will not
occur in a particular installation.
If this equipment does cause interference to radio or television reception, when it’s in
use, the user is encouraged to try to correct the interference by one or more of the
following measures:
A. Where it can be done safely, reorient the radio or TV receiving antenna.
B. To the extent possible, relocate the television, radio, or other receiver with respect
to the telephone equipment.
C. If your telephone product runs on AC power, plug your product into an AC outlet
that’s not on the same circuit as the one used by the radio or television.

FCC REGULATIONS CONTINUED
Warning: Modifying or tampering with the telephone's internal components can cause
a malfunction and might invalidate the telephone's warranty and void your FCC
authorization to operate it. If the trouble is harming the telephone lines, the telephone
company might ask you to disconnect the telephone until you have resolved the
problem.
1. Connection and use with the nationwide telephone network:
The FCC requires that you connect to a nationwide telephone network through a
modular telephone outlet which is TIA/EIA-IS-968 compliant. It is USOC jack type
RJ11C.
This equipment may not be used on coin service provided by the telephone
company. Connection to party lines is subject to state tariffs. Check with your local
telephone company.
2. Notification to the telephone company:
FCC rules require that upon request you provide the following information to the
phone company.
A. The line (telephone number) to which you will connect the telephone equipment,
and
B. The Registration Number and Ringer Equivalence Number (REN). These
numbers are found on the back or bottom of your telephone equipment.
The REN is useful to determine the quantity of devices you may connect to your
telephone line and still have all of those devices ring when your telephone numberis
called. In most, but not all areas, the sum all RENs should be 5 or less. To determine
the number of devices permitted in your area, contact your local telephone company.
3. Repair instructions:
If it is determined that your telephone equipment is malfunctioning, the FCC requires
that it not be used and be unplugged from the modular outlet until the problem has
been corrected. Repairs to this telephone equipment can be made only by the
manufacturer or its authorized agents, or by others who may be authorized by the
FCC. Unauthorized repairs void registration and warranty.
4. Rights of the telephone company:
If your product is causing harm to the telephone network, the telephone company
may temporarily discontinue your service. 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 given the opportunity to correct the problem, and 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 telephone equipment. If such changes are planned,
you will be notified in advance.
5. This product is compatible with inductively coupled hearing aids.
Note: This applies only if this product is equipped with a corded or cordless
handset.

•Choose the best location
•Connect the phone
•Choose the dialing mode
Where you place the phone affects the reception quality of the handset:
•Away from another cordless telephone
•Place the base near an AC electrical outlet and near telephone line jack
•Place the base away from metal walls and metal file cabinets
CAUTION: The cordless telephone operates at a frequency that may cause
interference to nearby TVs and VCRs; the base phone should not
be placed near, or on top of a TV or VCR. If interference is experi-
enced, moving the cordless telephone farther away from the TV or
VCR will often reduce or eliminate the interference.
Note: While the 2.4GHz frequency is inherently clearer, we suggest that
you do not use this phone within 20 feet of a working microwave.
The microwave produces frequencies in this range which may
cause interference. This interference is normal for all 2.4GHz
phones and should not be considered a product defect.
