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 ET-543. For this reason, the ET-
543 cordless phone should not be your
only telephone. To be safe, you should
alsohave aphonethatdoesnotrequire
AC power to operate (not a cordless
phone)soyoucanstillmakeandreceive
calls if there is an AC power failure.
This telephone has been tested and
found to comply with all applicable UL
and FCC standards.
Your ET-543 operates on standard ra-
dio frequencies, as allocated by the
FCC. Therefore, it is possible for other
radio units operating on similar fre-
quencies, within a certain area, to in-
advertently intercept your conversa-
tions and/or cause interference on
your cordless telephone. This lack of
privacy can occur with any cordless
telephone.
For your records, we urge you to
record the serial number of your phone
in the space below. The serial number
is located on the bottom panel of the
base.

READ THIS BEFORE
INSTALLATION
We have designed your telephone to
conform to federal regulations, and
you can connect it to most telephone
lines. However, 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 your
phone’s 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 phone 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 of your phone’s 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
Select a location for the telephone that
meets these requirements:
• Near an AC outlet
• Near a telephone line jack
• Out of the way of normal activities
• Away from electrical machinery,
electrical appliances, and metal
walls or filing cabinets
• Away from wireless intercoms,
alarms, and room monitors
The base’s location affects the phone’s
range. If you have a choice of several
locations, try each one to see which
provides the best performance.
If the phone line jack is not a modular
jack, you must update the wiring your-
self, using jacks and adapters avail-
able at your local RadioShack store.
Or, you can let the phone company up-
date the wiring for you.
Notes:
• The phone company will charge
you for the installation of the nec-
essary jacks.
• The USOC number of the jack to
be installed is RJ11C.
INSTALLING THE PHONE
Follow these steps to install the base
on a desk, shelf, or table.
1. Plug one end of the supplied mod-
ular cord into the phone jack on
the back of the base.
2. Plug the modular cord’s other end
into a modular phone line jack.
3. Insert the supplied AC adapter’s
barrel plug into the DC 12V jack on
the back of the base.
4. Plug the adapter into a standard
AC outlet.
For the best reception, fully extend the
base’s antenna and place it in a verti-
cal position.
Caution: You must use a 120V AC/
12V DC adapter that delivers at least
200 milliamps. Its center tip must be
positive, and its plug must correctly fit
the phone’s DC 12V jack. The supplied
adapter meets these requirements.
Using an adapter that does not meet
these requirements could damage the
phone or the adapter.

PREPARATION
CONNECTING THE
BATTERY
Before you use your phone for the first
time, you must connect and charge the
battery.
Slide off the battery compartment cov-
er on the back of the handset. Connect
the battery’s plug to the pins inside the
compartment.
Replace the cover, then follow the in-
structions under “Charging the Bat-
tery.”
CHARGING THE
BATTERY
Before you charge the battery, set
POWER to OFF. Then place the hand-
set on the cradle so the CHARGE/
TALK indicator lights and let the bat-
tery charge for about 15 hours.
When on the handset lights, re-
charge the battery. To avoid damage
to the battery, always recharge the
handset before battery power grows
too weak to light .
Notes:
• You can set POWER to ON while
the battery charges.
• If the CHARGE/TALK indicator
does not light when you place the
handset on the cradle, be sure the
battery is connected to the pins
inside the battery compartment
and the AC adapter is securely
connected to the base. Also,
check the charging contacts on

the handset and base. If the con-
tacts are dirty or tarnished, gently
clean them with a pencil eraser.
• About once a month, fully dis-
charge the battery by keeping the
handset off the cradle until
flashes, then return the
handset to the cradle and fully
recharge the battery. If you do not
fully discharge and recharge the
battery periodically, it loses its
ability to fully recharge.
• The first time you use your phone
after charging a new battery, the
handset might not work and might
sound an error tone when you
press
TALK. This might also occur
when you recharge a battery that
has been completely discharged.
If this happens, be sure the hand-
set is turned on, then return the
handset to the cradle for 5 sec-
onds. This resets the security
access code.
SETTING THE DIALING
MODE
Set TONE/PULSE on the back of the
base for the type of service you have.
If you are not sure which type you
have, do this test.
1. Set TONE/PULSE to TONE.
2. Lift the handset and listen for a
dial tone.
3. Press any number other than 0.
If the dial tone stops, you have
touch-tone service. Leave TONE/
PULSE set to TONE.
If the dial tone continues, you
have pulse service. Set TONE/
PULSE to PULSE.

OPERATION
Your ET-543’s LCD display shows
telephone numbers as you dial them or
when you recall them from memory. It
shows the current channel number and
lets you know when battery power is
growing weak or the phone is out of
range of the base. The display also
shows indicators when you press
FLASH/DEL or PAUSE.
MAKING/ANSWERING
A CALL
You can use your cordless telephone
in two ways: at the base or away from
the base.
Using the Handset
at the Base
You can use the handset at the base
like a regular corded telephone. Just
set POWER to ON and place the hand-
set in the cradle.
To answer a call, just lift the handset
from the base.
To make a call, lift the handset from
the base and press TALK so the key-
pad and the CHARGE/TALK indicator
on the base light.
Note: CH and the currently used
channel number appear on the display.
This number might change when you
return the handset to the base.
To disconnect a call, replace the hand-
set on the base.
Using the Handset
Away from the Base
To make or answer a call, set POWER
to ON and press TALK. The keypad
and CHARGE/TALK indicator light.
To disconnect a call, press TALK so
the keypad light and the CHARGE/
TALK indicator turn off.
Notes:
•CHand the currently used channel
number appear on the display.
• To conserve battery power, you
can turn off the handset’s power
when you are not making or
answering a call.

• You can make or answer a call on
a phone on the same line as the
cordless phone, even if the hand-
set is away from the base.
•RANGE appears when the dis-
tance from the handset to the
base is out of the phone’s range.
• The keypad lights on the handset
turn off if no button is pressed for
more than 13 seconds.
REDUCING
INTERFERENCE
To reduce interference, press CH to
switch to the next channel (25 chan-
nels in all) until you receive the best re-
ception. CH and the channel number
appear on the display.
USING REDIAL
To quickly redial the last number you
dialed, simply lift the handset from the
base and press TALK again so the
CHARGE/TALK indicator lights, and
then press REDIAL. The redialed num-
ber appears on the display.
The redial memory holds up to 80 dig-
its in the tone or pulse mode. The redi-
al memory also holds pause entries
(see “Entering a Pause” under “Memo-
ry Dialing”).
Note: We recommend you not use RE-
DIAL to dial numbers that include a
tone (*) entry (see “Using Tone Servic-
es on a Pulse Line”).
USING FLASH/DEL
Use FLASH/DEL on the handset to per-
form the switchhook operation for spe-
cial services, such as call waiting.
For example, if you have call waiting,
press FLASH/DEL to take an incoming
call without disconnecting the current
call. FLASH appears. Press FLASH/
DEL again to return to the first call.
