Each device that you connect to the
phone line draws power from the phone
line. We refer to this power draw as the
!
REN. The REN is shown on the bottom
device’s
ringer equivalence number
, or
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 m ore 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.

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 (standard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
1. Use a Phillips screwdriver to loosen
the screw in the battery compartment cover on the bottom of the
telephone, then lift open the cover.
2. Put the batteries into the compartment as indicated by the polarity
symbols (+ and –) marked inside.
3. Close the cover and tighten the
screw.
4. Be sure the

SELECTING A LOCATION
You can place the pho ne on a desk top
or table, or mount it on a telephone wa ll
plate or directly on the wall. Select a location that is:
• Near a telephone line jack
• Out of the way of normal activities
only
• Near an AC outlet (
an optional AC adapter; see “Connecting 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 modular 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.
if you use

Mounting the Phone on a Wall
You can mount your telephone on a wall
plate, or you can mount it direct ly on t he
wall using two screws (not supplied) with
heads that fit into the keyhole slots on
the bottom of the telephone.

You might prefer a longer cord for the
handset. Your local RadioShack store
has a wide selection of telephone accessories, including longer coiled handset
cords.
CONNECTING AN
OPTIONAL AC ADAPTER
Your telephone operates from telephone
line power. In some areas , howev er, t he
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 speakerphone does not work , connect an AC
adapter (RadioShack Cat. No. 273-
1454).
Cautions:
• The recommended adap ter supp lies

• The redial memory holds up to 32
digits in the pulse mode and 31

In some telephone systems, you must

wait for a second dial tone before you
can dial an outside number. You can
store the access code with the phone

CARE AND MAINTENANCE
Your RadioShack ET-148 20-Number M emory Speakerphone with Privacy is an example of superior desig n and craftsman ship. The followi ng suggestions w ill help you
care for your phone so you can enjoy it for years.
• Keep the phone dry. If it gets wet, wipe it dry immediately. Liquids might contain
minerals that corrode electronic circuits.
• Use and store the phone only in normal temperature environments. High temperature extremes can shorten the life of electronic devices, and distort or melt plastic parts.
• Handle the phone gently and carefully. Dropping it can damage circuit boards
and cases and can cause the phone to work improperly.
• Keep the phon e away from dust and dirt, which can cause prema ture wear of
parts.
• Wipe the phone with a damp cloth occasionally to keep it looking new. Do not use
harsh chemicals, cleaning solvents, or strong detergents to clean your phone.
Modifying or tampering with the telephone’s internal components can cause a malfunction and might invalidate your telephone’s warranty and void your FCC authorization to operate it. If your telephone is not perform ing as it should, tak e it to your local
RadioShack store f or assistance. If the trouble is harming the p hone lines, the telephone company might ask you to disconnect your phone until you have resolved the
problem.
THE FCC WANTS YOU TO KNOW
In the unlikely event that your phone causes problems on the phone line, the phone
company can temporarily discontinue your service. If this happens, the phone company attempts to notify you in advance. If advance notice is not practical, the phone company notifies you as soon as possible and advises you of your right to file a complaint
with the FCC.
Also, the phone company can make c hanges to its lines, equipment, operations, or
procedures that could affect the operat ion of this tele phone. Th e te lephon e company
notifies you of these changes in advance, so you can take the necessary steps to prevent interruption of your telephone service.
15
43-637 .fm Page 16 Friday, August 13, 1999 10:45 AM
LIGHTNING
Your telephone has built-in protection circuits to reduce the risk of damage from surges in telephone line and power line current. T hese prot ection c ircuits meet or exc eed
the FCC requirements. However, lightning striking the telephone o r power lines can
damage your telephone.
Lightning damage is not common. Nevertheless , if you live in an a rea that has frequent electrical storms, we sugge st that you unplu g your telephone during storms to
reduce the possibility of damage.
