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-557. To be safe,
you should also have a phone that
does not need AC power to operate
(not a cordless ph one) so you can still
make and receive calls if there is an
AC power failure.

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 bo ttom panel of the
base.

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 t he line, add up all
the RENs. If the total is more than five,
your phones might not ring. In rural ar­eas, a total REN of three might im pair
ringer operation. If ringer operation is
impaired, remove a device from the
line.

FCC STATEMENT

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 located
on the bottom panel of the base.

You must not connect your

phone to any of the following:

• coin-operated syst e ms

• party-line systems

• most electronic key phone sys­tems

Some cordless t eleph ones operat e on
frequencies that may cause interfer­fence to nearby TVs and VCRs. To
minimize or prevent such interference,
the base of the cordless telephone
should not be placed nea r or on top of
TVs or VCRs. If interference is experi­enced, moving the cordless telephone
farther away from the TV or VCR will
often reduce or eliminate the i nterfer­ence.

INSTALLATION

SELECTING A LOCATION

You can place the phone on a desktop
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 inter­coms, alarms, and room monitors

• away from other cordless phones

The base’s location affects the hand­set’s range. If you have a choice of
several locations, try each to see
which provides the best performance.

Notes:

• Your telephone connects directly
to a modular telephone line jack. If
your phone line jack is not a mod­ular jack, you can update the wir­ing yourself, using jacks and
adapters available at your local
Radio Shack store. Or, you can let
the phone company update the
wiring for you.

you for the installation of neces­sary jacks.
