Important Note: 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 ET-536/ET-549. To be
safe, you should also have a phone
that does not need AC power to oper-
ate (not a cordless phone) so you can
still make and receive calls if there is
an AC power failure.
Warning: To prevent fire or shock
hazard, do not expose this product to
rain or moisture.
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.
READ THIS BEFORE
INSTALLATION
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 is shown
on the bottom of the base.
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.
FCC STATEMENT
This telephone complies with Part 68
of
FCC Rules
. You must, upon re-
quest, provide the FCC Registration
Number and the REN to your phone
company. These numbers are located
on the bottom panel of the base.
Note: You must not connect your
phone to any of the following:
• coin-operated systems
• party-line systems
• most electronic key phone sys-
tems

INSTALLATION
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
• near a telephone line jack
• out of the way of normal activities
• away from electrical machinery,
electrical appliances, metal walls
or filing cabinets, wireless inter-
coms, alarms, and room monitors

to a modular telephone line jack. If
your phone line jack is not a mod-
ular jack, you can update the wir-
ing yourself, using jacks and
adapters available at your local
RadioShack store. Or, you can let
the phone company update the
wiring for you.
• The phone company will charge
you for the installation of neces-
sary jacks.

tery then charge it for about 14 hours.
1. Remove the screw on the battery
compartment cover on the bottom
of the handset. Press down and
slide off the handset’s battery
compartment cover in the direc-
tion of the arrow.
2. Insert the battery pack’s plastic
connector into the phone’s socket.
The plug fits only one way.
3. Replace the cover and tighten the
screw.
4. To charge the battery, simply
place the handset on the base.
43-1036.fm Page 9 Tuesday, August 17, 1999 9:52 AM

The CHARGE indicator on the base
lights.
Recharge the battery when the BATT
LOW indicator flashes.
Notes:
• If the CHARGE indicator does not
light when you place the handset
on the base, be sure the battery
and AC adapter are correctly and
securely connected.
• When you first use the phone after
charging or recharging the battery,
the phone might not work and you
might hear an error tone. If this
happens, return the handset to
the base for about 5 seconds.
• If the BATT LOW indicator does
not light, but the phone does not
work, recharge the battery. The
battery charge might be too low to
light 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 every
3 seconds. If this happens, you
cannot make another call on the
phone until you recharge the bat-
tery.
• About once a month, fully dis-
charge the battery by keeping the
handset off the base until the
BATT LOW indicator lights. Other-
wise, the battery loses its ability to
fully recharge.
• 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 battery gets completely dis-
charged, the ET-536/ET-549
loses the security access-protec-
tion code. To reset the security
code, place the handset on the
base and charge the battery.
• The supplied battery should last
for about a year. When the battery
loses its ability to fully recharge,
order a replacement battery from
your local RadioShack store (see
“Replacing the Battery” on Page
19.

have pulse service, you can still use
these special tone services by follow-
ing these steps.
1. Be sure P• •Tis set to P.
2. Lift the handset from the cradle or
press TALK.
3. Dial the service’s main number.
4. When the service answers, press
TONE. Any additional numbers
you dial are sent as tone signals.
5. After you complete the call, return
the handset to the cradle or press
TALK. The phone automatically
resets to the pulse mode.

TROUBLESHOOTING
We do not expect you to have any problems with your phone, but if you do, the fol-
lowing suggestions might help.
Problem Suggestion
Low volume or unusual
sounds. Someone has picked up another phone on the same line. Hang up the other phone.
Severe noise interference. • Press CH to change the channel.
• Keep the handset away from computers,
remote control toys, wireless microphones,
alarm systems, intercoms, room monitors,
fluorescent lights, and electrical appli-
ances.
• Move to another location or turn off the
source of interference.
The phone cannot be oper-
ated at a useful distance from
the base because the signal
becomes weak or noisy
(handset’s range has
decreased).
• Fully extend the base’s antenna in a verti-
cal position.
• Be sure neither antenna is touching a
metal surface.
• Return the handset to the cradle, and
recharge the battery.
The phone does not work or
works poorly. Be sure the base’s phone line cord and AC adapter are correctly and securely connected,
and the battery is charged.
The handset battery does not
charge. • Check the charging contacts on the hand- set and base. If they are dirty, clean them
with a pencil eraser.
• Be sure the battery is connected correctly.
43-1036.fm Page 16 Tuesday, August 17, 1999 9:52 AM

17
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
Handset does not ring or
receive a page. • The battery pack might be weak. Charge the battery.
• Extend the base’s antenna vertically.
• Move the handset closer to the base.
• Move the base away from other electrical
devices and sources of noise.
The handset stops working or

CARE AND MAINTENANCE
Your RadioShack ET-536 10 Channel/ET-549 25-Channel Cordless Telephone with
10-Number Memory is an example of superior design and craftsmanship. The fol-
lowing 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.
Handle the phone gently and carefully. Dropping it can damage cir-
cuit boards and cases and can cause the phone to work improperly.
Use and store the phone only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices and
distort or melt plastic parts.
Keep the phone away from dust and dirt, which can cause premature
wear of parts.
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.

REPLACING THE
BATTERY
If you follow the instructions in “Con-
necting and Charging the Battery” on
Page 9, the battery should last about
one year. If the battery will not hold a
charge for more than 2 hours after an
overnight charge, replace the battery
with a new 3.6 V, 300 mAh battery with
a connector that fits the socket in the
battery compartment. You can order a
replacement battery through your local
RadioShack store.
Install the new battery as described
below, then charge the battery (see
“Connecting and Charging the Bat-
tery” on Page 9).
Note: To avoid losing phone numbers
stored in memory, try to install and be-
gin charging the new battery within 1
minute.
1. Remove the screw on the battery
compartment cover on the bottom
of the handset. Press down and
slide off the handset’s battery
compartment cover in the direc-
tion of the arrow.
2. Gently pull on the battery connec-
tor to disconnect it, then remove
the battery.
3. Insert a fresh battery and insert its
connector into the socket inside
the battery compartment.
4. Replace the cover and tighten the
screw.
Cautions:
• You must use a replacement bat-
tery of the same size and type.
• Do not dispose of the battery in a
fire because it might explode.
• Do not open or mutilate the bat-
tery.
• Be careful not to short the battery
by touching it with conducting
materials, such as rings, brace-
lets, and keys. The battery or con-
ductor might overheat and burn.
Important: This product contains a re-
chargeable nickel cadmium battery. At
the end of the battery’s useful life, it
must be recycled or disposed of proper-
ly. Contact your local, county, or state
hazardous waste management authori-
ties for information on recycling or dis-
posal programs in your area. Some
options that might be available are: mu-
nicipal curb-side collection, drop-off box-
es at retailers such as your local
RadioShack store, recycling collection
centers, and mail-back programs.

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.
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.
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 your local Ra-
dioShack store for help
If you cannot eliminate the interfer-
ence, the FCC requires that you stop
using your phone.
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 damage
from surges in telephone line and pow-
er line current. This lightning protection
meets or exceeds FCC requirements.
However, lightning striking the tele-
phone 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 sug-
gest you unplug your phone during
storms to reduce the possibility of
damage.
