CAUTION

43-103 7.fm Page 3 Tuesday, August 17, 1999 10:05 AM

Important: Cordless phones such as
this one require AC power to operate.
When AC power is off, you cannot dial
out or receive incoming calls using
your ET-537. For this reason, the E T­537 should not be your only telephone.
To be safe, you should also have a
phone that does not need AC power to
operate (not a cordless pho ne) so y ou
can still make and receive calls if there
is an AC power failure.

Warning: To prevent fire or shock haz­ard, do not expose t his product to rain
or moisture.

RISK OF ELECTRIC SHOCK.

DO NOT OPEN.

CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE
COVER OR BA CK. NO USER-S ERVICE­ABLE PARTS INSIDE. REFER SERVIC­ING TO QUALIFIED PERSONNEL.

This symbol is intended to aler t you

READ THIS BEFORE
INSTALLATION

We have designed your te lephone to
conform to federal regulations, and
you can connect it to mos t 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 on the bottom of the base.

If you are using more than one phone
or other device on t he line, add up all
the RENs. If the total is more than five,
your phone might not ring. In rural ar­eas, a total REN of three might im pair
ringer operation. If ringer operation is
impaired, disconnect one of the devic­es from the line.

Note:

Some cordless phones operate
at frequencies that might cause inter­ference to nearby TVs and V CRs. 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.

FCC STATEM ENT

This telephone complies with Part 68

FCC Rules

of
quest, provide the FCC Registration
Number and the REN to your phone
company. These numbers are on the
bottom of the phone’s base.

You must not connect your phone to
any of the following:

• Coin-operated systems

• Party-line systems

• Most electronic key phone sys­tems

Note:

Your telephone operates on
standard radio frequencies, as allocat­ed by the FCC. Even though the ac­cess-protection code prevents un­authorized use of your pho ne li ne, it is
possible for other radio units operating
on similar frequencies within a certain
area to unintentionally intercept your
conversations and/or cause interfer­ence. This lack of privacy can occur
with any cordless phone.

INSTALLATION

Important:

for the phone (see “Selecting a Loca­tion”), you must install the phone in the
following order before you use it for the
first ti me.

1. Install the handset’s antenna (see
“Installing the Handset’s An­tenna” on Page 7).

2. Connect the battery to the hand­set (see “Connecting the Battery”
on Page 7).

3. Connect the base to power (see
“Connecting Power” on Page 7).

4. Charge the phone’s battery for
about 24 hours (see “Charging
the Battery” on Page 8).

5. Install the base and connect it to
your phone line (see “Installing the
Base” on Page 9).

After you select a location

SELECTING A LOCATION

You can place your ph one on a desk,
shelf, or table, or mount it on a wall.
Select a location that is:

• Away from computers, remote
control toys, 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 to see which pro­vides the best performance.

Notes:

• If the phone line jack is not a mod­ular jack, you must update the wir­ing. You can do this 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 install ation of the nec­essary jacks.

• The USOC number of the jack t o
be installed is RJ11W for a wall
jack or RJ11C for a wall plate.

• Near an AC outlet

• Near a telephone line jack

INSTALLING THE
HANDSET’S ANTENNA

Insert the antenna into the hole at the
top of the handset, then rotate the an­tenna clockwise until it is secure.

CONNECTING THE
BATTERY

Your phone comes with a recharge­able nickel-cadmium b attery installed.
However, before you use the phone for
the first time, you must connect the
battery and charge it for about 24
hours.

Follow these steps to connect the bat­tery.

2. Pull and lift the front tab on the
battery restraining strap to remove
it.

3. Connect the battery’s wires to the
battery connector inside the c om­partment, then insert the battery.

Note:

The battery’s connector fits
into the connector inside the com­partment only one way. Do not
force it.

4. Replace the battery restraining
strap and the cover.

After you connect the battery, you
must connect power, then charge the
battery.

CONNECTING POWER

Caution:

DC adapter that delivers at least 150
milliamps. Its plug must correctly fit the
phone’s
plied adapter meets these require­ments. Using an adapter that does not
meet these requirements could dam­age the phone or the adapter.

You must use a 120V AC/9V

POWER 9V DC

jack. The sup-

1. While lifting up on the battery
compartment cover’s latch on the
back of the handset, pull the cover
up to remove it.

7

43-103 7.fm Page 8 Tuesday, August 17, 1999 10:05 AM

1. Insert the supplied AC adapter’s
barrel plug into the

POWER 9V DC

jack on the back of the base.

2. Plug the adapter into a standard
AC outlet.

CHARGING THE
BATTERY

Before you connect the phone to the
phone line and use the phone for the
first time, or whenever you install a
new battery, make sure

ON

on the handset is set to
charge the battery for about 24 hours
by placing the handset on the cradle so
the CHARGE indicator on the base
lights.

The phone charges whenever the
handset is on the base. You can re­charge the battery at any time, but you
must be sure to recharge it when the
handset sounds a be ep every 7 sec­onds.

Notes:

• If the CHARGE indicator on the
base does not light when you
place the handset on the cradle,

RINGER OFF/

OFF

, then

be sure the AC adapter is
securely connected to the base.

Also, check the charging contacts
on the handset and base. If the
contacts are dirty or tarnished,
gently clean them with a pencil
eraser.

• A full charge lasts about 168
hours if you leave the handset off
the base and do not make any
calls.

• About once a month, fully dis­charge the battery. Otherwise, the
battery loses its ability to fully
recharge. To fully discharge the
battery, set
the handset to

RINGER OFF/ON

ON

and keep the

on

handset off the cradle until the
handset beeps every 7 seconds.
Then return the handset to the
cradle, set

OFF,

and recharge the b attery for

RINGER OFF/ON

to

about 10 hours.

• When the battery cannot fully
recharge, replace it with a new
one. For the best performance,
you should replace the supplied
battery about once a year — more
often if it is used heavily. See
“Replacing the Battery’’ on
Page 21.
