This telephone has been tested and
found to comply with all applicable UL
and FCC standards.
Warning: To prevent fire or shock
hazard, do not expose this product
to rain or moisture.
We recommend you record your
phone’s serial number here. The num-
ber is on the bottom of the base.
CAUTION
RISK OF ELECTRIC SHOCK.

CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE
COVER OR BACK. NO USER-SERVICE-
ABLE PARTS INSIDE. REFER SERVIC-
ING TO QUALIFIED PERSONNEL.
Important Note: Cordless phones
such as your ET-598 require AC power
to operate. When the AC power is off,
you cannot dial out or receive incoming
calls using this phone. 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 pow-
er failure.
This symbol is intended to alert you
to the presence of uninsulated dan-
gerous voltage within the product’s
enclosure that might be of sufficient
magnitude to constitute a risk of
electric shock. Do not open the
product’s case.
This symbol is intended to inform
you that important operating and
maintenance instructions are in-
cluded in the literature accompany-
ing this product.
Your telephone operates on standard
radio frequencies as allocated by the
FCC. Even though the access protec-
tion code prevents unauthorized use
of your phone line, it is possible for
other radio units operating on similar
frequencies within a certain area to
unintentionally intercept your conver-
sations and/or cause interference.
This lack of privacy can occur with any
cordless phone.

READ THIS BEFORE
INSTALLATION
FCC STATEMENT
This telephone complies with Part 68
of FCC Rules. Upon request, you must
provide the FCC Registration Number
and the REN to your phone company.
These numbers are located on the bot-
tom of the base.
Each device that you connect to the
phone line draws power from the
phone line. We refer to this power draw
as the device’s ringer equivalence
number, or REN. The REN for your
ET-598 is located on the bottom of the
base.
Note: You must not connect your
phone to any of the following:
If you are using more than one phone
or other device on the line, add up all
the RENs. If the total is more than five,
your phones might not ring. In rural ar-
eas, a total REN of three might impair
ringer operation. If ringer operation is
impaired, remove a device from the
line.

INSTALLATION
Or, you can connect it to two separate
1-line modular telephone jacks using
the supplied 2-line modular cord and a
1-line modular cord (such as Ra-
dioShack Cat. No. 279-356, not sup-
plied).
SELECTING A
LOCATION
You can place the phone on a desk top
or table, or mount it on a wall. Select a
location that is:
• near an AC outlet
Notes:
• near a telephone line jack
• out of the way of normal activities
• Two-line and single-line modular
cords look alike but are wired dif-
ferently. To use the ET-598’s two
lines, use only the supplied two-
line modular cord to connect to a
two-line modular jack.
• away from electrical machinery,
electrical appliances, metal walls
or filing cabinets, wireless inter-
coms, alarms, and room monitors
• You can also use the ET-598 with
a single 1-line modular jack.
• away from other cordless phones
The base’s location affects the hand-
set’s range. If you have a choice of
several locations, try each to see
which provides the best performance.
If your phone wiring does not have a
modular phone jack, you can:
• Update the wiring yourself, using
jacks and adapters available at
your local RadioShack store
• Have the phone company update
the wiring for you
MOUNTING/CONNECTING
THE PHONE
Note: The USOC number of the jack to
be installed is RJ14C for a two-line
baseboard jack or RJ14W for a two-
line wall-plate jack.
To use both of the ET-598’s lines, you
must connect it to two separate tele-
phone lines. Each of these lines must
have its own phone number. If you do
not have two telephone lines, contact
your phone company to get a second
line.
Caution: The supplied RadioShack
adapter was designed specifically for
your ET-598. Use only the supplied
adapter.
You can connect your telephone to a
2-line modular telephone jack using
the supplied 2-line modular cord.

• If the BATT LOW indicator does
not flash and the phone does not
work, recharge the battery pack.
(The battery charge might be too
low to flash the indicator.)
• If the battery pack gets weak dur-
ing a call, the handset sounds a
beep every 30 seconds, and the
BATT LOW indicator flashes. If
this happens, you must recharge
the battery pack before you can
make another call.
• About once a month, fully dis-
charge the battery pack by keep-
ing the handset off the base until
the BATT LOW indicator flashes.
Otherwise, the battery pack loses
its ability to fully recharge.
Recharge the battery pack when the
BATT LOW indicator flashes.
• Using a pencil eraser, clean the
charging contacts on the handset
and the base about once a month
to make sure they are not dirty or
tarnished.

• If the CHARGE indicator does not
light when you place the handset
on the base, be sure the battery
pack and AC adapter are correctly
and securely connected.

Testing Stored Emergency
Numbers
In some telephone systems, you must
dial an access code (9, for example)
and wait for a second dial tone before
you can dial an outside number. You
can store the access code with the
phone number. However, you should
also store a pause after the access
code to allow the outside line time to
connect.
If you store an emergency service’s
number (police department, fire de-
partment, ambulance) and you choose
to test the stored number, make the
test call during the late evening or early
morning hours to avoid peak demand
periods. Also, remain on the line to ex-
plain the reason for your call.
To enter a 2-second pause, press
REDIAL/P. For a longer pause, press
REDAIL/P additional times.

The handset stops working or
works poorly during a call.
• Fully extend the base’s antenna, and place
it in a vertical position.
• Move the handset closer to the base.
• Be sure the handset’s battery pack is
charged. (If the battery power is too low, it
does not have enough power to light the
BATT LOW indicator.)
• If the base loses power while the handset
is off of it, the security access-protection
code might change. Restore power to the
base, then place the handset back on the
base and leave it there for a few seconds.
The call is too noisy.
Change channels, or hang up and redial the
number.
If you still have problems, disconnect the phone. If other phones on the same line
work properly, the fault is in this phone or its installation. If you cannot find the prob-
lem, take your phone to your local RadioShack store for assistance.

CARE AND MAINTENANCE
Your RadioShack ET-598 25-Channel Two-Line Cordless Telephone with Dual Key-
pads is an example of superior design and craftsmanship. The following suggestions
will help you care for your cordless telephone so you can enjoy it for years.
Keep the phone dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the phone only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices(,
damage batteries,) and distort or melt plastic parts.
Keep the phone away from dust and dirt, which can cause premature
wear of parts.
Handle the phone gently and carefully. Dropping it can damage cir-
cuit boards and cases and can cause the phone to work improperly.
Wipe the phone with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong deter-
gents to clean the phone.
Modifying or tampering with the telephone’s internal components can cause a mal-
function and might invalidate your telephone’s warranty and void your FCC authori-
zation to operate it. If your phone is not performing as it should, take it to your local
RadioShack store for assistance. If the trouble is affecting the phone lines, the
phone company might ask you to disconnect your phone until you have resolved the
problem.

3. Insert a fresh battery pack and
plug its connector into the socket
inside the battery compartment.
REPLACING THE
BATTERY PACK
If you follow the instructions in “Con-
necting and Charging the Battery
Pack” on Page 12, the battery pack
should last about a year. If the battery
pack will not hold a charge for more
than 2 hours after an overnight charge,
replace it with a new 3.6 V, 300 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.
4. Replace the cover and secure it
with the screw.
Cautions:
• You must use a replacement bat-
tery pack of the same size and
type.
• Do not dispose of the battery pack
in a fire because it might explode.
• Do not open or mutilate the bat-
tery pack.
Install the new battery pack as de-
scribed below, then charge the battery
pack for 14 hours before you use it.
• Be careful not to short the battery
pack by touching it with conduct-
ing materials, such as rings,
bracelets, and keys. The battery
pack or conductor might overheat
and burn.
Note: To avoid losing phone numbers
stored in memory, try to install and be-
gin charging the new battery pack
within 1 minute after removing the old
one.
Important: This product contains a re-
chargeable nickel cadmium battery
pack. At the end of the battery pack’s
useful life, it must be recycled or dis-
posed of properly. Contact your local,
county, or state hazardous waste man-
agement authorities for information on
recycling or disposal programs in your
area. Some options that might be
available are: municipal curb-side col-
lection, drop-off boxes at retailers such
as your local RadioShack store, recy-
cling collection centers, and mail-back
programs.
1. Remove the screw from the bat-
tery compartment cover on the
bottom of the handset, then press
down and slide off the cover.
2. Gently pull on the battery connec-
tor to disconnect it, then remove
the battery pack.

If you cannot eliminate the interfer-
ence, 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
discontinue your service. If this hap-
pens, the phone company attempts to
notify you in advance. If advance no-
tice is not practical, the phone compa-
ny notifies you as soon as possible and
advises you of your right to file a com-
plaint with the FCC.
Some cordless phones operate at fre-
quencies that might cause interference
to nearby TVs and VCRs. To minimize
or prevent such interference, the base
of the cordless phone should not be
placed near or on top of a TV or VCR.
LIGHTNING
Your telephone has built-in lightning
protection to reduce the risk of dam-
age from surges in telephone line and
power line current. This lightning pro-
tection meets or exceeds FCC re-
Also, the phone company can make
changes to its lines, equipment, opera-
tions, or procedures that could affect
the operation of this telephone. The
telephone company notifies you of
these changes in advance, so you can
take the necessary steps to prevent in-
terruption of your telephone service.
quirements.
However,
lightning
striking the telephone or power lines
can damage your telephone.
Lightning damage is not common.
Nevertheless, 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 damage.
Your phone might cause TV or radio
interference 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 the inter-
ference.
Try to eliminate the interference by:
• Moving your phone away from the
receiver
• Connecting your phone to an AC
outlet that is on a different electri-
cal circuit from the receiver
• Contacting
