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 areas, 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 request,
provide the FCC Registration Number
and the REN to your phone company.
These numbers are shown on the bot-
tom 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 systems

PREPARATION
INSTALLING BATTERIES
Your telephone uses two AAA batteries
(not supplied) for power to retain the
numbers you store in memory. For the
best performance and longest life, we
recommend alkaline batteries, such as
Cat. No. 23-555.
Cautions:
• Always use fresh batteries of the
required size and recommended
type.
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
1. Use a Phillips screwdriver to loosen
the screw in the battery compart-
ment cover on the bottom of the
telephone, then lift open the cover.
2. Put the batteries into the compart-
ment as indicated by the polarity
symbols (+ and –) marked inside.
3. Close the cover and tighten the
screw.
4. Be sure the NORM/STORE BATT
TEST switch on the back of the
phone is set to NORM (see “Testing/
Replacing the Batteries”).
Testing/Replacing the Batteries
To test the batteries’ strength at any
time, temporarily slide NORM/STORE
BATT TEST (on the back of the tele-
phone) to STORE BATT TEST.
If the BATT TEST indicator does not
light or is dim, replace the batteries.
43-637.fm Page 5 Friday, August 13, 1999 10:45 AM

To prevent the loss of stored numbers
when the batteries are removed, replace
the batteries within 5 minutes.
Set NORM/STORE BATT TEST back to
NORM.
SELECTING A LOCATION
You can place the phone on a desk top
or table, or mount it on a telephone wall
plate or directly on the wall. Select a lo-
cation that is:
• Near a telephone line jack
• Out of the way of normal activities
• Near an AC outlet (
only
if you use
an optional AC adapter; see “Con-
necting an Optional AC Adapter” on
Page 8)
Notes:
• Your telephone connects directly to
a modular telephone line jack. If
your phone line jack is not a modu-
lar jack, you can update the wiring
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 Phone on a
Desk Top
Plug one end of the supplied long modu-
lar cord into the TEL LINE jack on the
back of the phone. Then plug the other
end into a modular phone line jack.
Mounting the Phone on a Wall
You can mount your telephone on a wall
plate, or you can mount it directly on the
wall using two screws (not supplied) with
heads that fit into the keyhole slots on
the bottom of the telephone.
Note: If you are mounting the phone di-
rectly on the wall, drill two holes 315/16
inches (100 mm) apart. Thread the two
screws into the wall, letting the heads
extend about 1/8inch (3 mm).

1. Press in on the side of the bracket
nearest the DESK label and lift the
bracket. Rotate the bracket 180°
and insert it into the WALL slots,
then push it upward to secure it.
2. Plug one end of the supplied short
modular cord into the TEL LINE jack
on the back of the phone and plug
the other end into a modular phone
line jack. Then align the base’s key-
hole slots with the wall plate studs
(or screws) and slide the base
downward to secure it.
3. Lift out the handset guide, rotate it
180°, then snap it back into place so
it holds the handset.
Note: The handset holder above the
handset cradle lets you place the
handset on the holder without dis-
connecting the call.
CONNECTING THE
HANDSET
Plug one end of the coiled cord into the
modular jack on the handset. Then con-
nect the other end to the jack on the side
of the telephone base.

You might prefer a longer cord for the
handset. Your local RadioShack store
has a wide selection of telephone acces-
sories, including longer coiled handset
cords.
CONNECTING AN
OPTIONAL AC ADAPTER
Your telephone operates from telephone
line power. In some areas, however, the
telephone line might not provide enough
power to operate all of your telephone’s
features. If the speakerphone’s volume
is too low, even with the volume control
set to its highest setting, or if the speak-
erphone does not work, connect an AC
adapter (RadioShack Cat. No. 273-
1454).
Cautions:
• The recommended adapter supplies
6 volts DC, delivers at least 150 mil-
liamps, and has a barrel plug which
properly fits the phone’s DC 6V jack.
Using an adapter that does not meet
these specifications might damage
the phone or the adapter.
• To prevent damage to the adapter
and the telephone, always plug the
adapter into the telephone before
you plug it into the AC outlet. Always
unplug the AC adapter from the AC
outlet first, then unplug the barrel
plug from the phone.
1. Plug the adapter’s barrel plug into
the DC 6V jack on the back of the
telephone.
2. Route the adapter cable through the
strain relief slot on the bottom of the
telephone.
3. Plug the other end of the adapter in-
to a standard AC outlet.

SETTING THE DIALING
MODE
Set MODE on the back of the base for
the type of service you have (tone or
pulse). If you are not sure which type
you have, do this test.
1. Set MODE to TONE.
2. Lift the handset and listen for a dial
tone.
3. Press any number other than 0.
Note: If your phone system requires
that you dial an access code (9, for
example) before you dial an outside
number, do not press the access
code either.
4. If the dial tone stops, you have
touch-tone service. Leave MODE set
to TONE.
If the dial tone continues, you have
pulse service. Set MODE to PULSE.
SETTING THE RINGER
SWITCH
Set RINGER on the back of the tele-
phone to select the desired ringer vol-
ume:
HI — Normal ringer volume.
LO — Reduced ringer volume.
OFF — The telephone does not ring
Note: With the phone’s ringer off, you
can still make calls using the ET-148.
You can also receive calls if you hear an-
other telephone on the same line ringing.
