Important:
FCC STATEMENT
• 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-928. For this reason, the ET-928
should not be your only telephone.
To be safe, you should also have a
phone that does not require AC
power to operate (not a cordless
phone), so you can still make and
receive calls if there is an AC power
failure.
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 on the label on the
bottom of the base.
You must not connect your phone to any
of the following:
• Coin-operated systems
• Party-line systems
• Some cordless phones operate at
frequencies that might cause inter-
ference to nearby TVs and VCRs.
To minimize or prevent such interfer-
ence, the base of the cordless
phone should not be placed near or
on top of a TV or VCR.
• Most electronic key phone systems
READ THIS BEFORE
INSTALLATION
Your telephone conforms to federal reg-
ulations, and you can connect it to most
telephone lines. However, each device
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 the 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 impair ringer
operation. If ringer operation is impaired,
remove a device from the line.

INSTALLATION
• The USOC number of the jack to be
installed is RJ11C (RJ11W if you
want to mount it on a wall plate).
INSTALLING THE
HANDSET’S
ANTENNA
Caution: You must use an AC adapter
that supplies 9 volts with the center tip
set to positive. It must deliver 500 milli-
amps, and its plug must properly fit the
telephone’s DC 9V jack. The supplied
AC adapter meets these specifications.
Using an adapter that does not meet
these specifications could damage the
telephone or the adapter.
Insert the antenna into the
hole on the top of the hand-
set, then twist the antenna
clockwise until it is secure.
SELECTING A LOCATION
You can place the phone on a desk top,
or mount it on a wall plate or directly on
a wall. Select a location that is:
Placing on a Desk Top
• near an AC outlet
1. Push in the two tabs on the top of
the mounting bracket, then lift off
just the upper part of the bracket.
• near a telephone line jack
• away from electrical machinery,
electrical appliances, metal walls or
filing cabinets, wireless intercoms,
alarms, and room monitors
illus -- enlarge to fill
space
• away from other cordless phones
The base’s location affects the phone’s
range. If you have a choice of several lo-
cations, try each to see which provides
the best performance.
2. Insert the supplied AC adapter’s
barrel plug into the DC 9V jack on
the back of the base, route the
adapter cord through the strain relief
slot and the hole on the bracket,
then push in the mounting bracket’s
upper end to click the bracket into
place.
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.

CONNECTING AND
CHARGING THE BATTERY
PACK
on the base if it is wall-mounted
(using the slot on the back of the
handset); however, the battery pack
will not fully charge in this position.
The ET-928 comes with a rechargeable
nickel-cadmium battery pack in the
handset, but not connected. Before us-
ing your phone, you must connect the
battery pack, then charge it for about 24
hours.
• When you first use your phone after
charging or recharging the battery
pack, the handset might not work or
it might sound an error tone when
you press TALK. If this happens,
place the handset on the base for
about 5 seconds, then try again.
1. Slide off the handset’s battery com-
partment cover.
• If the CHARGE indicator does not
light when you place the handset on
the cradle, be sure the battery and
AC adapter are correctly and
securely connected.
2. Insert the battery pack’s
connector with its flat
side up into the phone’s
socket. The connector
fits only one way.

you do not, the ET-928 sounds a
long beep, all indicators stop flash-
ing, and you must start over again at
Step 1.
Notes:
• You can store special banking or
telephone service numbers (such as
access codes or account numbers)
in memory, but for security pur-
poses, we recommend that you do
not store private numbers (such as

Storing a Pause
In some telephone systems, you must
dial an access code (9, for example) and
wait for a second dial tone before you
can dial an outside number. You can
store the access code with the phone
number. However, you should also store
a pause after the access code to allow
the outside line time to connect.
Testing Stored Emergency
Numbers
If you store an emergency service’s
number (police department, fire depart-
ment, ambulance) and you want to test
the stored number, make the test call
during the late evening or early morning
hours to avoid peak demand periods. Al-
so, remain on the line to explain the rea-
son for your call.

one of the ET-928’s memory locations.
This is called chain dialing. Chain dialing
is useful for dialing special services such
as alternate long distance or bank-by-
phone.
• If a call comes in during an intercom
conversation, either of the intercom
parties can answer the call, but the
intercom call is disconnected.

USING AN OPTIONAL
HEADSET
Your ET-928’s handset is equipped with
a headset jack on top. This jack allows
you to connect an optional headset
(such as RadioShack Cat. No. 43-194)
for hands-free conversation — perfect
for when you are working in the yard or
garage. You must also have a handset
holder (such as Cat. No. 43-197, not
supplied) for the handset so you can
carry it with you while you use the head-
set.

CARE AND MAINTENANCE
Your RadioShack ET-928 Digital Spread Spectrum 900 MHz Cordless Speakerphone
is an example of superior design and craftsmanship. The following suggestions will
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 con-
tain minerals that can corrode electronic circuits.
Handle the phone gently and carefully. Dropping it can damage its cir-
cuit boards and cases and cause it to work improperly.
Use and store the phone only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices, dam-
age batteries, and distort or melt plastic parts.
Keep the phone away from dust and dirt, which can cause premature
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 the phone.
Modifying or tampering with the phone’s internal components can cause a malfunc-
tion and might invalidate its warranty and void your FCC authorization to operate it. If
your phone is not performing as it should, take it to your local RadioShack store for
assistance. If the trouble is affecting the phone lines, the phone company might ask
you to disconnect your phone until you have resolved the problem.

Cautions:
REPLACING THE
BATTERY PACK
• Use only a replacement battery
pack of the required type (3.6 V, 600
mAh rechargeable battery pack).
If you follow the instructions in “Connect-
ing and Charging the Battery Pack” on
Page 11, the battery pack should last
about one year. If the battery pack will
not hold a charge for more than 2 hours
after an overnight charge, replace it with
a new 3.6 V, 600 mAh battery pack that
has a connector which fits the socket in
the battery compartment. You can order
a replacement battery pack through your
local RadioShack store.
• Do not dispose of the battery pack in
a fire because it can explode.
• Do not open or mutilate the battery
pack. Swallowing battery parts can
be fatal.
• Be careful not to short the battery
pack with conducting materials,
such as rings, bracelets, and keys.
The battery pack or conductor might
overheat and burn.
Install the new battery pack as de-
scribed here, then charge the battery
pack for 24 hours.
• At the end of a nickel-cadmium bat-
tery’s useful life, it must be recycled
or disposed of properly. Contact
your local, county, or state hazard-
ous waste management authorities
for information on recycling or dis-
posal programs in your area. Some
options that might be available are:
municipal curbside collection, drop-
off boxes at retailers such as your
local RadioShack store, recycling
collection centers, and mail-back
programs.
Note: To avoid losing phone numbers
stored in memory, try to install and begin
charging the new battery pack within
about 2 minutes.
1. Press down and slide off the hand-
set’s battery compartment cover.

w/batt installed
2. Gently pull out the battery pack’s
connector to disconnect it, then
remove the battery pack.
3. Insert a fresh battery pack and plug
its connector with the flat side up
into the socket inside the battery
compartment. The connector fits
only one way.
4. Replace the cover.

To eliminate interference, you can try
one or more of the following corrective
measures:
THE FCC WANTS YOU TO
KNOW
In the unlikely event that your phone
causes problems on the phone line, the
phone company can temporarily discon-
tinue your service. The phone company
normally attempts to notify you in ad-
vance. 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.
• Reorient or relocate the receiving
antenna
• Increase the distance between the
equipment and the radio or TV
• Use outlets on different electrical cir-
cuits for the equipment and the
radio or TV
Consult your local RadioShack store if
the problem still exists.
Also, the phone company can make
changes to its lines, equipment, opera-
tions, or procedures that could affect the
operation of this telephone. The phone
company normally notifies you of these
changes in advance, so you can take
the necessary steps to prevent interrup-
tion of your phone service.
LIGHTNING
Your phone has built-in protection cir-
cuits to reduce the risk of damage from
surges in phone line current. These pro-
tection circuits meet or exceed FCC re-
quirements. However, lightning striking
the phone lines can damage your
phone.
This equipment complies with the limits
for a Class B digital device as specified
in Part 15 of FCC Rules. These limits
provide reasonable protection against
radio and TV interference in a residential
area. However, your equipment might
cause TV or radio interference even
when it is operating properly.
Lightning damage is not common. Nev-
ertheless, if you live in an area which
has severe electrical storms, we sug-
gest that you unplug your phone during
storms to reduce the possibility of dam-
age.
