Additional Info
Operating Range
This cordless telephone operates with the maximum power allowed by the
Federal Communications Commission (FCC). Even so, this handset and
telephone base can communicate over only a certain distance - which can
vary with the locations of the telephone base and handset, the weather, and
the layout of your home or office.
When the handset is out of range, the handset displays CONNECTING...
If there is a call while the handset is out of range, it might not ring, or if it
does ring, the call might not connect well when you press /FLASH. Move
closer to the telephone base, then press /FLASH to answer the call.
If the handset moves out of range during a telephone conversation, there
might be interference.
To improve reception, move closer to the telephone base.
Maintenance
Taking care of your telephone: Your cordless telephone contains
sophisticated electronic parts, so it must be treated with care.
Avoid rough treatment: Place the handset down gently. Save the original
packing materials to protect your telephone if you ever need to ship it.
Avoid water: Your telephone can be damaged if it gets wet. Do not use the
handset outdoors in the rain, or handle it with wet hands. Do not install the
telephone base near a sink, bathtub or shower.
Electrical storms: Electrical storms can sometimes cause power surges
harmful to electronic equipment. For your own safety, take caution when
using electrical appliances during storms.
Cleaning your telephone: Your telephone has a durable plastic casing that
should retain its luster for many years. Clean it only with a soft cloth slightly
dampened with water or a mild soap. Do not use excess water or cleaning
solvents of any kind.
Remember that electrical appliances can cause serious injury if used when
you are wet or standing in the water. If the telephone base should fall
into the water, DO NOT RETRIEVE IT UNTIL YOU UNPLUG THE POWER
CORD AND TELEPHONE LINE CORD FROM THE WALL. Then remove the
telephone by the unplugged cords.

Additional Info
About Cordless Telephones
Privacy: The same features that make a cordless telephone convenient
create some limitations. Telephone calls are transmitted between the
telephone base and the cordless handset by radio waves, so there
is a possibility that the cordless telephone conversations could be
intercepted by radio receiving equipment within range of the cordless
handset. For this reason, you should not think of cordless telephone
conversations as being as private as those on corded telephones.
Electrical power: The telephone base of this cordless telephone must be
connected to a working electrical outlet. The electrical outlet should not
be controlled by a wall switch. Calls cannot be made from the cordless
handset if the telephone base is unplugged or switched off, or if the
electrical power is interrupted.
Potential TV interference: Some cordless telephones operate at
frequencies that may cause interference to televisions and VCRs. To
minimize or prevent such interference, do not place the telephone base
of the cordless telephone near or on top of a TV or VCR. If interference
is experienced, moving the cordless telephone farther away from the TV
or VCR often reduces or eliminates the interference.
Rechargeable batteries: Exercise care in handling batteries in order not
to create a short circuit with conducting material such as rings, bracelets,
and keys. The battery or conductor may overheat and cause harm.
Observe proper polarity between the battery and the battery charger.
Nickel-metal hydride rechargeable batteries: Dispose of these batteries
in a safe manner. Do not burn or puncture the battery. Like other
batteries of this type, if burned or punctured, they could release caustic
material which could cause injury.

Additional Info
FCC Information
This equipment has been tested and found to comply with the requirements
for a Class B digital device under Part 15 of the Federal Communications
Commission (FCC) rules. These requirements are intended 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 or 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 receiver.
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
Consult your local RadioShack store or an experienced radio/TV
technician for help.
Changes or modifications not expressly approved by RadioShack may cause
interference and void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation. Privacy of
communications may not be ensured when using this telephone.
To ensure safety of users, the FCC has established criteria for the amount of
radio frequency energy that can be safely absorbed by a user or bystander
according to the intended usage of the product. This product has been
tested and found to comply with the FCC criteria. The handset may be
safely held against the ear of the user. The telephone base shall be installed
and used such that parts of the user’s body other than the hands are
maintained at a distance of approximately 20 cm (8 inches) or more.
This equipment complies with Part 68 of the FCC rules and with technical
requirements adopted by the Administrative Council for Terminal
Attachments (ACTA). The label on the back or bottom of this equipment
contains, among other things, a product identifier in the format US:
AAAEQ##TXXXX. This identifier must be provided to your local telephone
company upon request.

Additional Info
The plug and jack used to connect this equipment to premises wiring and
the telephone network must comply with applicable Part 68 rules and
technical requirements adopted by ACTA. A compliant telephone cord and
modular plug is provided with this product. It is designed to be connected
to a compatible modular jack that is also compliant. An RJ11 jack should
normally be used for connecting to a single line and an RJ14 jack for two
lines. See Installation Instructions in the user’s manual.
The Ringer Equivalence Number (REN) is used to determine how many
devices you may connect to your telephone line and still have them ring
when you are called. The REN for this product is encoded as the 6th and
7th characters following the US: in the product identifier (e.g., if ## is 03,
the REN is 0.3). In most, but not all areas, the sum of all RENs should be
five (5.0) or less. For more information, please contact your local telephone
company.
This equipment may not be used with Party Lines. If you have specially
wired alarm dialing equipment connected to your telephone line, ensure
the connection of this equipment does not disable your alarm equipment.
If you have questions about what will disable alarm equipment, consult your
telephone company or a qualified installer.
If this equipment is malfunctioning, it must be unplugged from the modular
jack until the problem has been corrected. Repairs to this telephone
equipment can only be made by the manufacturer or its authorized agents.
For repair procedures, follow the instructions outlined under the Limited
Warranty.
