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 incom-
ing calls using your ET-550. 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.
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.
We recommend you record your
phone’s serial number here. The num-
ber is on the bottom 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 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 shown
on the bottom 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
• 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.
Caution: The supplied RadioShack
adapter was designed specifically for
your ET-550. Use only the supplied
adapter.
Notes:
• Your telephone connects directly
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 USOC number of the jack to
be installed is RJ11C (RJ11W if
you want to mount it on a wall
plate).
Placing the Base
on a Desk Top
Follow these steps when you place
the base on a desk, shelf, or table.
1. Plug one end of the supplied mod-
ular cord into the TEL LINE jack on
the back of the base.
2. Insert the supplied AC adapter’s
barrel plug into the DC IN 9V jack

compartment cover on the bottom
of the handset. Then press down

tion of the arrow.
