Important:
FCC STATEMENT
• 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.
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
• When AC power is lost, PFappears
on the display to show a power fail-
ure occurred and the TAD-728 loses
the security access-protection code
connection between the base and
the handset. When power is
restored, put the handset on the
base briefly to restore this connec-
tion so you can use the handset.
• 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 elimi-
nate interference, you can try one or
more of the following corrective mea-
sures.
READ THIS BEFORE
INSTALLATION
We have designed your phone to con-
form to federal regulations and you can
connect it to most phone lines. However,
each device that you connect to the tele-
phone 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.
• Reorient or relocate the receiving
antenna.
• Increase the distance between the
equipment and the radio or TV.
• Use outlets on different electrical cir-
cuits for the equipment and the
radio or TV.
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 ru-
ral areas), your phones might not ring. If
ringer operation is impaired, remove one
of the devices from the line.
Consult your local RadioShack store if
the problem still exists.

you are not sure of the type of
power supply to your home, consult
your dealer or local power company.

4. Replace the cover.
• If the battery pack is completely dis-
charged, the handset might lose its
security access-protection code. To
reset the code, return the handset to
the base for about 2 seconds.
To charge the battery pack, place the
handset either faceup or facedown on
the base. The IN USE/CHARGE indica-
tor on the base lights and Charging
and then No calls appear on the
handset display.
• Using a pencil eraser, clean the
charging contacts on the handset
and the base about once a month.
Recharge the battery pack when Re-
charge! Battery low flashes on
the handset display.
• If the battery pack becomes weak
during a call, the handset beeps
every 16 seconds and Recharge!
Batterylowappears. When this
happens, you cannot make another
call on the phone until you recharge
the battery pack.
• About once a month, fully discharge
the battery pack by keeping the
handset off the base until the hand-
set display shows Recharge!
Batterylow. Otherwise, the bat-
tery pack loses its ability to fully
recharge.
Important: Be sure the battery pack is
properly connected before you try to
charge it. The IN USE/CHARGE indica-
tor lights when the handset is on the
base, even if the battery pack is not con-
nected.
• If the handset display does not show
Recharge! Battery low, but
the phone does not work, recharge
the battery pack. (The battery
charge might be too low to light the
indicator.)
Notes:
• When you first use the phone after
charging or recharging the battery
pack, the phone might not work and
you might hear three beeps when
you press TALK. If this happens,
return the handset to the base for
about 2 seconds. This resets the
security access-protection code.
• If you are not going to use your
phone for an extended period of
time, disconnect the battery pack.
This increases the battery pack's
usable life.

CALLER ID OPERATION
If you subscribe to Caller ID service from
your phone company, the phone compa-
ny sends information about the call, as
well as the time and date, between the
first and second rings of every call you
receive.
REVIEWING CALLER ID
RECORDS
Callers List
The callers list memory stores the infor-
mation of up to the 30 most recent call-
ers. When you begin reviewing the list, a
callers list header appears to indicate
how many new calls have been received
since your last review and how many
viewed callers are kept in the list. If a
call is received after 30 callers have al-
ready been stored, the oldest item is re-
moved from memory.
The TAD-728 displays this information
when it receives a call, and it stores up
to 30 Caller ID records for later review. It
also shows if caller information is un-
available or if the name and number
were blocked by the caller (see “Caller
ID Messages” on Page 26).
If you subscribe to Call Waiting with
Caller ID, you will hear a tone through
the handset when a call comes in, then
the Caller ID record appears. If you want
to answer the incoming call, press
FLASH/MENU. To resume the previous
phone conversation, press FLASH/MENU
again.
CALL WAITING OPTIONS
The Caller ID service provides you with
more choices on how to handle a sec-
ond call when you are already on the
phone. You can switch between the call-
ers, have a 3-way conference call with
both callers, send the second caller to
your voice mail, or answer the second
caller with a prerecorded message ask-
ing them to hold the line.
If the TAD-728's Caller ID memory be-
comes full, any new call replaces the
oldest call's record.

SELECTING AN
OUTGOING MESSAGE
The TAD has two prerecorded messag-
es. One asks the caller to leave a mes-
sage (“Hello, no one is available to take
your call. Please leave your message af-
ter the tone.”), the other is an announce-
ment and does not let the caller leave a
message (“Hello, no one is available to
take your call.”). You can also record
your own message (see “Recording an
Outgoing Message”). Use the REC TIME
switch to select which message you
want. When you set it to either 1 or 4
(minutes), the normal message is se-
lected and the TAD records each incom-
ing message for 1 or 4 minutes. When
you set it to ANS. ONLY, the announce-
only message is selected.
Hints:
• Do not tell callers that you are not
home. Instead, say that you cannot
come to the phone right now.
• When you record an announce-
ment-only message, be sure that
the caller understands he or she
cannot leave a message.
Follow these steps to record your outgo-
ing message.

CARE AND MAINTENANCE
Your RadioShack
TAD-728 900 MHz Digital Spread Spectrum Cordless Telephone
is an example of superior design and craftsmanship. The following suggestions will
help you care for your TAD-728 so you can enjoy it for years.
Keep the TAD-728 dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the TAD-728 only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices, dam-
age the battery pack, and distort or melt plastic parts.
Keep the TAD-728 away from dust and dirt, which can cause premature
wear of parts.
Handle the TAD-728 gently and carefully. Dropping it can damage cir-
cuit boards and cases and can cause the TAD-728 to work improperly.
Use only fresh batteries of the required size and recommended type.
Batteries can leak chemicals that damage your TAD-728’s electronic
parts.
Wipe the TAD-728 with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong deter-
gents to clean the TAD-728.
Modifying or tampering with the TAD-728’s internal components can cause a mal-
function and might invalidate its warranty and void your FCC authorization to oper-
ate it. If your TAD-728 is not performing as it should, take it to your local
RadioShack store for assistance. If the trouble is affecting the telephone lines, the
phone company can ask you to disconnect your TAD-728 until you have resolved
the problem.

• Do not dispose of the battery in a
fire because it can explode.
REPLACING THE
BATTERY PACK
• Do not open or mutilate the battery.
Swallowing the battery can be fatal.
If you follow the instructions in “Connect-
ing and Charging the Battery Pack” on
Page 12, the battery pack should last
about one year. If the battery pack does
not hold a charge for more than 2 hours
after an overnight charge, replace it with
a new 3.6-volt, 600 mAh battery pack
with a connector that fits the socket in
the battery compartment. You can order
a replacement battery pack through your
local RadioShack store.
• Be careful not to short the battery
with conducting materials, such as
rings, bracelets, and keys. The bat-
tery or conductor might overheat
and burn.

phone can use nickel
cadmium rechargeable
batteries. At the end of a

If you cannot eliminate the interference,
the FCC requires that you stop using
your phone.
THE FCC WANTS YOU TO
KNOW
In the unlikely event that your phone
causes problems on the phone line, the
phone company can temporarily discon-
tinue your service. If this happens, the
phone company attempts to notify you in
advance. If advance notice is not practi-
cal, the phone company notifies you as
soon as possible and advises you of
your right to file a complaint with the
FCC.
Some cordless telephones operate on
frequencies that might cause interfer-
ence to nearby TVs and VCRs. To mini-
mize or prevent such interference, the
base of the cordless telephone should
not be placed near or on top of a TV or
VCR.
LIGHTNING
Also, the phone company can make
changes to its lines, equipment, opera-
tions, or procedures that could affect the
operation of this telephone. The tele-
phone company notifies you of these
changes in advance, so you can take
the necessary steps to prevent interrup-
tion of your telephone service.
Your telephone has built-in lightning pro-
tection to reduce the risk of damage
from surges in telephone line and power
line current. This lightning protection
meets or exceeds FCC requirements.
However, lightning striking the tele-
phone or power lines can damage your
telephone.
Your phone might cause TV or radio in-
terference even when it is operating
properly. To determine whether your
phone is causing the interference, turn
off your phone. If the interference goes
away, your phone is causing it. Try to
eliminate the interference by:
Lightning damage is not common. Nev-
ertheless, if you live in an area that has
severe electrical storms, we suggest
that you unplug your phone during
storms to reduce the possibility of dam-
age.
• moving your phone away from the
receiver
• connecting your phone to an AC
outlet that is on a different electrical
circuit from the receiver
• contacting your local RadioShack
store for help
