FEATURES
Your RadioShack ET-687 Two-Line
900MHz Digital Spread Spectrum Cordless Telephone lets you place and receive calls on two separate telephone
lines. It is designed to exacting standards that ensure reliability, long life, and
outstanding performance.
Its features include:
Spread Spectrum Technology —
spreads the signal across several frequencies, providing additional security
for your phone conversations.
900 MHz Operation — provides longer
range and less interference than many
other cordless phones.
Handset Volume Control — lets you
adjust the volume of the sound you hear
through the handset.
Two-Line Telephone System — lets
you easily handle two telephone lines at
the same time. You can also use both lines
at once to make three- or four-way conference calls.
Line Status Indicators — show if a line
is available, in use, or on hold.
Speakerphone — lets you make or answer calls without using the handset.
Headset Jack — lets you talk with
hands-free convenience using an optional headset.
Ample Talk and Standby Time — the
supplied battery pack (when fully
charged) provides 4 hours of continuous
talk time or 7 days of standby time.
20 Channels — automatically selects a
clear channel when you make or answer a
call.
20-Number Memory Dialing — lets you
store up to 20 numbers in memory (ten
each in the handset and base) for easy
dialing.
Security Access-Protection Code —
automatically prevents other cordless
phone users from using your phone line
while the handset is off the base.
Paging/Two-Way Intercom — lets you
send a signal from the base to the handset,
or from the handset to the base, to page
someone or locate the handset when it is
away from the base. If someone answers,
you can use the ET-687 as an intercom.
Adjustable Ringers — give you two volume settings for the handset and base
ringers.
Dual Keypads — a full set of keys on
both the ET-687’s handset and base lets
you use either keypad to make and answer calls or use the phone’s features.
Any Key Answer — you can answer a
call by pressing any number key on the
handset or base.
COM-LOK® — ensures that other cordless phone users cannot use your phone
line when the handset is on the base.

Redial — lets you quickly redial the last
number dialed.
Flash — sends an electronic switchhook
signal for use with special phone services, such as Call Waiting.
Tone/Pulse Dialing — lets you use either type of service, and you can easily
switch from pulse to tone dialing for special services such as bank-by-phone.
Hearing-Aid Compatibility — lets you
use your phone with hearing aids that
have a T (telephone) switch.
This telephone has been tested and
found to comply with all applicable standards.
Your telephone operates on standard radio frequencies as allocated by the FCC.
Even though the security access-protection 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 conversations and/or
cause interference. This lack of privacy
can occur with any cordless phone.
Warning: To reduce the risk of fire
or shock hazard, do not expose
this product to rain or moisture.
CAUTION
RISK OF ELECTRIC SHOCK.
DO NOT OPEN.
We recommend you record your phone’s
serial number here. The number is on
the bottom of the base.

CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE
COVER OR BACK. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.
Serial Number: __________________
Important Note: Cordless phones such
as your ET-687 require AC power to operate. When the AC power is off, you
cannot dial out or receive incoming calls
using this phone. To be safe, you should
also have a phone that does not need AC
power to operate (not a cordless phone)
so you can still make and receive calls if
there is an AC power failure.
This symbol is intended to alert you to
the presence of uninsulated dangerous voltage within the product’s enclosure that might be of sufficient
magnitude to constitute a risk of electric shock. Do not open the product’s

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 for your ET-687 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
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.
4
FCC STATEMENT
This telephone complies with Part 68 of
FCC Rules. Upon request, you must provide the FCC registration number and
the REN to your phone company. These
numbers are 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 systems

INSTALLATION
MOUNTING THE PHONE
You can place the ET-687’s base on a
desk or table, or mount it on a standard
wall plate or directly on a wall. Choose a
location that is:
• near an AC outlet
• near a modular telephone line jack
You can connect the ET-687 to the telephone lines in one of three ways:
• connect two lines through a two-line
modular phone jack
• connect two lines through two oneline modular phone jacks
• connect one line through a one-line
modular phone 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.
Caution: The supplied RadioShack
adapter was designed specifically for
your ET-687. Use only the supplied
adapter.
Connecting to the Phone Lines
To take full advantage of the ET-687’s
capabilities, you must have two phone
lines with separate phone numbers. If
you have only one line, you can order a
second from your phone company.
6
Notes:
• Your phone connects directly to a
modular phone line jack. If your
phone wiring does not have a modular jack, you can update it using
jacks and adapters available at your
local RadioShack store, or have the
phone company update it for you.
• The line that connects a two-line
phone jack to the phone company
wiring must be twisted-pair cable.
Otherwise, you might hear interference (crosstalk) between the two
lines.
• The USOC number of the two-line
jack to be installed is RJ14C
(RJ14W for a wall plate). The USOC
number of a single-line jack is
RJ11C.

43-687.fm Page 12 Friday, August 13, 1999 11:12 AM
4. Replace the cover.
• If the battery pack becomes weak
during a call, the handset beeps every 3 seconds. If this happens, you
must recharge the battery pack before you can make another call.
To charge the battery pack, place the
handset on the base either faceup or
facedown. The CHARGE indicator on
the base lights.
• Using a pencil eraser, clean the
charging contacts on the handset
and the base about once a month.
CHARGE
Indicator
Recharge the battery pack when the
handset beeps every 3 seconds or its
line indicators flash every 3 seconds.
Important: Be sure the battery pack is
properly connected before you try to
charge it. The CHARGE indicator lights
when the handset is on the base, even if
the battery pack is not connected.
Notes:
• When you first use the phone after
charging or recharging the battery
pack, it might not work and you
might hear an error tone when you
press LINE 1 or LINE 2. If this happens, return the handset to the base
for about 5 seconds. This resets the
security access-protection code.
12
• If the battery pack becomes completely discharged or the base loses
power while the handset is away,
the security access-protection code
needs to be reset. To reset the security code, return the handset to the
base. If it was the handset that lost
power, leave the handset on the
base to charge the battery pack.
• About once a month, fully discharge
the battery pack by keeping the handset off the base until the low battery
indications (flashing line indicators
and beeping) appear. Otherwise, the
battery pack loses its ability to fully recharge.
• The supplied battery pack should
last about one year. When it loses

replacement battery pack from your
local
RadioShack store (see
“Replacing the Battery Pack” on
Page 26).

the handset light, and the CHARGE indicator on the base lights.
4. When you hang up, the phone automatically resets to pulse dialing.
USING PAGE/INTERCOM
You can use the ET-687 as a two-way
pager and intercom between the base and
the handset. This is useful if the handset is
away from the base and you want to locate it, or if you want to have a conversation between someone with the handset
and someone at the base.
To page the base from the handset,
press INTCM. The base and handset
ring. Press INTERCOM on the base to answer the page. Both line indicators on
the handset light, and the CHARGE indicator on the base lights.
To end an intercom call, press INTCM on
the handset, press INTERCOM on the
base, or hang up the handset.
During a call, you can page someone at
the base or the handset. Press INTERCOM (on the base) or INTCM (on the
handset). The current call is put on hold.
• To transfer the call, press INTERCOM or INTCM again when the person at the handset or base answers.
• To start a three-way call, tell the person at the base or handset to press
LINE 1 (or LINE 2), then press the
same button twice on your keypad
when they answer the page.
Notes:
• You cannot page the base or handset if it is already in use. You will
hear a warning tone.

43-687.fm Page 20 Friday, August 13, 1999 11:12 AM
• If a call comes in during an intercom
conversation, either of the intercom
parties can answer the call as they
normally would. Simply press the
ringing line’s button. The intercom
call automatically disconnects.
MEMORY DIALING
You can store up to 20 numbers in memory (ten each in the handset’s and base’s
memory), then dial a stored number by
pressing a one-digit memory location
number.
Use the supplied memory directory
stickers to record your stored numbers.
(Use a pencil in case you need to
change the number later.) Peel the
backing from each sticker and attach
them to the phone as shown.
Notes:
• Each number stored in the handset’s memory can be up to 20 digits,
and each number stored in the base
can be up to 16 digits.
• You cannot dial a number stored in
one memory location (the base or
the handset) using the keypad on
the other.
• An error tone sounds and the phone
exits the storing process if you wait
more than 20 seconds between
each keypress.
Storing a Number in Memory
Follow these steps to store a number in
the handset’s memory. To store a number in the base’s memory, start at Step 2.
1. Lift the handset.
2. Press MEM. The CHARGE indicator
on the base flashes, or the line indicators on the handset flash.
3. Enter the number and any tone and
pause entries (see “Using Tone Services on a Pulse Line” on Page 18
and “Entering a Pause” on Page 21).
Note: Each tone or pause entry
uses one digit of memory.
20
43-687.fm Page 21 Friday, August 13, 1999 11:12 AM
4. Press MEM, then enter the memory
location number (0–9). A long beep
confirms that the number is stored.
Note: If the phone sounds five quick
beeps, you have made an entry
error, and the number was not
stored. Start again from Step 2.
To replace a stored number, simply store
a new number in its place.
To erase a stored number, press MEM
twice, then press the number for the
memory location (0–9) you want to clear.
A long beep sounds.
Note: You cannot store a number at the
base while the handset is in use.
Entering 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.
To enter a 2-second pause, press PAUSE
on the handset or base. You can add
more pause entries for a longer pause.
Dialing a Memory Number
To dial a number stored in the handset’s
memory, lift the handset and press either
line button. When you hear a dial tone,
press MEM and enter the memory location number for the number you want to
dial.
To dial a number stored in the base’s
memory, press either line button. When
you hear a dial tone, press MEM and enter the memory location number for the
number you want to dial.
Chain-Dialing Service Numbers
For quick recall of numbers for special
services (such as bank by phone), store
each group of numbers in its own memory location.
Dial the service’s main number first.
Then, at the appropriate place in the
call, press MEM and the number for the
location where the additional information
is stored.
Testing Stored Emergency
Numbers
If you store an emergency service’s
number (police department, fire department, ambulance) and you choose to
test the stored number, make the test
call during the late evening or early
morning hours to avoid peak demand
periods. Also, remain on the line to explain the reason for your call.

USING A HEADSET
You can talk with hands-free convenience using an optional headset that
has a 3/32-inch (2.5-mm) plug. Contact
your local RadioShack store for a suitable headset.
To connect the headset, open the rubber cover marked
on the side of the
handset, then insert the headset’s plug
into the jack.
With a headset connected, you can
make or answer calls as usual using the
speakerphone or the keys on the handset.
You can use a handset holder (available
at your local RadioShack store) to hang
the handset on your belt for greater convenience.
When you finish using the headset, disconnect it from the handset and close
the rubber cover to protect the jack.
22
Notes:
• Connecting a headset disconnects
the handset’s earpiece and microphone, but it does not affect the ET687’s speakerphone.
• VOL s or t on the handset also controls the connected headset’s volume.
• If you place the handset on the base
face down to recharge it while the
headset is connected, be sure the
handset seats properly.

CARE AND MAINTENANCE
Your RadioShack ET-687 Two-Line 900MHz Digital Spread Spectrum Cordless Telephone is an example of superior design and craftsmanship. The following suggestions
will help you care for your ET-687 so you can enjoy it for years.
Keep the ET-687 dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the ET-687 only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices, damage battery packs, and distort or melt plastic parts.
Keep the ET-687 away from dust and dirt, which can cause premature
wear of parts.
Handle the ET-687 gently and carefully. Dropping it can damage circuit
boards and cases and can cause the ET-687 to work improperly.
Use only a battery pack of the required size and recommended type.
Batteries can leak chemicals that damage your ET-687’s electronic
parts.
Wipe the ET-687 with a damp cloth occasionally to keep it looking new.
Do not use harsh chemicals, cleaning solvents, or strong detergents to
clean the ET-687.
Modifying or tampering with the ET-687’s internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. If
your ET-687 is not performing as it should, take it to your local RadioShack store for
assistance. If the trouble is affecting the telephone lines, the phone company can ask
you to disconnect your ET-687 until you have resolved the problem.

REPLACING THE
BATTERY PACK
If you follow the instructions in “Connecting and Charging the Battery Pack” on
Page 11, the battery pack should last
about one year. If the battery pack does
not hold a charge for more than 2 hours
after an overnight charge, replace it with
a new 3.6-volt, 600 mAh battery pack
with a connector that fits the socket in
the battery compartment. You can order
a replacement battery pack through your
local RadioShack store.
Install the new battery pack as described below, then charge it for about
24 hours.
Note: To avoid losing memory numbers,
try to install and begin charging the new
battery pack within 1 minute.
1. Press down and slide off the battery
pack compartment cover as shown.
4. Replace the cover.
Cautions:
• You must use a replacement battery
pack of the same size and type.
• Do not dispose of the battery pack in
a fire because it might explode.
• Do not open or mutilate the battery
pack.
• Be careful not to short the battery
pack by touching the connector’s
pins with conducting materials, such
as rings, bracelets, and keys. The
battery pack or conductor might
overheat and burn.
If you have trouble replacing the battery
pack, take the phone to your local RadioShack store for assistance.
2. Unfasten the plastic retainer strap
and lift the battery pack out of the
compartment, then gently pull on the
battery connector to disconnect it.
3. Insert the new battery pack’s connector into the socket in the compartment, place the battery pack into
the compartment, and refasten the
retainer strap.
26
Important: This product contains a rechargeable nickel-cadmium battery
pack. At the end of the battery pack’s
useful life, it must be recycled or disposed of properly. Contact your local,
county, or state hazardous waste management authorities for information on
recycling or disposal programs in your
area. Some options that might be available are: municipal curb-side collection,
drop-off boxes at retailers such as your
local RadioShack store, recycling collection centers, and mail-back programs.

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
changes to its lines, equipment, operations, or procedures that could affect the
operation of this telephone. The telephone company notifies you of these
changes in advance, so you can take the
necessary steps to prevent interruption
of your telephone service.
Your phone might cause TV or radio interference even when it is operating
properly. To determine whether your
phone is causing the interference, turn
off your phone. If the interference goes
away, your phone is causing it. Try to
eliminate the interference by:
If you cannot eliminate the interference,
the FCC requires that you stop using
your phone.
Some cordless telephones operate on
frequencies that might cause interference to nearby TVs and VCRs. To minimize or prevent such interference, the
base of the cordless telephone should
not be placed near or on top of a TV or
VCR.
LIGHTNING
Your telephone has built-in lightning protection to reduce the risk of damage
from surges in telephone line and power
line current. This lightning protection
meets or exceeds FCC requirements.
However, lightning striking the telephone or power lines can damage your
telephone.
Lightning damage is not common. Nevertheless, if you live in an area that has
severe electrical storms, we suggest
that you unplug your phone during
storms to reduce the possibility of damage.
• moving your phone away from the
receiver
• connecting your phone to an AC
outlet that is on a different electrical
circuit from the receiver
• contacting your local RadioShack
store for help
