FEATURES
Your RadioShack TAD-728 900 MHz
Digital Spread Spectrum Cordless Telephone uses advanced cordless telephone technology to give you superior
audio quality and extended range.
The TAD (Telephone Answering Device)
has about a 15-minute record capacity
and stores all messages on a microchip.
This gives you advanced capabilities
over tape-based answering machines.
For example, you can delete individual
messages and save the rest. Because
your TAD is fully digital, there are no
tapes to bother with, no tape mechanisms to wear out, and no lost me ssages if power fails.
The remote operation feature lets you
access your TAD from a touch-tone
phone, and guides you through system
operation with voice prompts.

Important:
• Cordless phones such as this one
require AC power to operate. When
the AC power is off, you cannot dial
out or receive incoming calls using
your TAD-728. To be safe, you
should also have a phone that does
not need AC power to operate (not a
cordless phone) so you can still
make and receive calls if there is an
AC power failure.

READ THIS BEFORE
INSTALLATION
We have designed your phone to conform to federal regulations and you can
connect it to most phone lines. However,
each device that you connect to the telephone line draws power from the line.
We refer to this power draw as the
phone's ringer equivalence number, or
REN. The REN is on the bottom of your
phone.
If you use more than one phone or other
device on the line, add up all the RENs.
If the total is more than five (three in rural areas), your phones might not ring. If
ringer operation is impaired, remove on e
of the devices from the line.
FCC STATEMENT
Your telephone complies with Part 68 of
FCC Rules. You must, upon request,
provide the FCC registration number
and the REN to your phone company.
These numbers are on the bottom of the
base.
You must not connect your phone to any
of the following:
• coin-operated systems
• party-line systems
• most electronic key phone systems
This equipment complies with the limits
for a Class B digital device as specified
in Part 15 of FCC Rules. These limits
provide reasonable protection against
radio and TV interference in a residential
area. However, your equipment might
cause TV or radio interference even
when it is operating properly. To eliminate interference, you can try one or
more of the following corrective measures.
• Reorient or relocate the receiving
antenna.
• Increase the distance between the
equipment and the radio or TV.
• Use outlets on different elec trical circuits for the equipment and the
radio or TV.
Consult your local RadioShack store if
the problem still exists.

INSTALLATION
MOUNTING THE PHONE
You can place the TAD-728's base on a
desk or table, mount it on a standard
wall plate, or mount it directly on a wall.
Choose a location that is:
• near an AC outlet
• near a telephone line jack
• out of the way of normal activities
• away from electrical machinery,
electrical appliances, metal walls or
filing cabinets, wireless intercoms,
alarms, and room monitors
• away from other cordless phones
The base's location affects the handset's range. If you have a choice of several locations, try each to see which
provides the best performance.
