FEATURES
Your RadioShack ET-685 2-Line 900-
MHz Spread Spectrum Cordless Speak-
erphone uses advanced cordless tele-
phone technology to give you superior
audio quality and extended range. The
ET-685 lets you make and receive calls
on two separate telephone lines.
The ET-685’s Caller ID records each
caller’s telephone number (and name, if
available in your area) and the day and
time of the call, as provided by your local
phone company to Caller ID service
subscribers. If you subscribe to Call
Waiting with Caller ID, the ET-685 can
even show you incoming caller informa-
tion when you are already on the phone.
Its other features include:
900 MHz Operation — provides longer
range and less interference than many
other cordless phones.
Two-Line Telephone System — lets
you easily handle two telephone lines at
the same time. You can use both lines to
make 3- or 4-way conference calls, or
one line for data communication while
you are talking on the other.
Dual Keypads — a full set of keys on
both the ET-685’s handset and base lets
you use either keypad to make and an-
swer calls or use the phone’s features.
Speakerphone — lets you make or an-
swer calls without using the handset.
Ample Talk and Standby Time — the
supplied battery pack provides 4 hours
of continuous talk time or 7 days of
standby time (when fully charged).
40-Number Memory Dialing — lets you
store up to 40 numbers in memory (30 in
the handset and 10 in the base) for easy
dialing.
Paging/Two-Way Intercom System —
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-685 as an intercom.
Dual Volume Control – let you adjust
the volume you hear through the hand-
set and speakerphone.
Adjustable Ringer — lets you choose
high or low volume for both lines’ ring-
ers.
Wall Mountable — you can mount the
ET-685 on the wall to save space on
your desk top.
Headset Jack — lets you make or an-
swer calls with hands-free convenience
using an optional headset.
Spread Spectrum Technology —
spreads the signal across several fre-
quencies, providing additional security
for your phone conversations.

set the ET-685 so you can answer a call
by lifting the handset from the base,
pressing any key on the base, or press-
ing any key on the handset when it is
away from the base.
Redial — lets you quickly redial the last
number dialed.

hook signal for use with special phone
services, such as Call Waiting.
Tone/Pulse Dialing — lets you use
your phone with either type of service,
and you can easily switch from pulse to
tone dialing for long-distance, bank-by-
phone, or other special services.

Important:
• Cordless phones such as this one
require AC power to operate. When
the AC power is off, you cannot dial
out or receive incoming calls using
your ET-685. 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.
• When AC power is lost, the ET-685
loses the security access-protection
code connection between the base
and the handset. When power is
restored, put the handset on the
base briefly to restore this connec-
tion so you can use the handset.
IMPORTANT CALLER ID
INFORMATION
To use the phone’s Caller ID and Caller
ID with Call Waiting features, you must
be in an area where those services are
available and you must subscribe to
those services through your local phone
company.
Where Caller ID is offered, one or more
options are generally available:
• caller’s number only
• caller’s name only
• caller’s name and number
READ THIS BEFORE
INSTALLATION
We have designed your phone to con-
form to federal regulations and you can
connect it to most phone lines. However,
each device that you connect to the tele-
phone line draws power from the line.
We refer to this power draw as the
phone's ringer equivalence number, or
REN. The REN is on the bottom of your
phone.
If you use more than one phone or other
device on the line, add up all the RENs.
If the total is more than five (three in ru-
ral areas), your phones might not ring. If
ringer operation is impaired, remove one
of the devices from the line.
FCC STATEMENT
Your 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 bottom of the
base.
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–685’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 accessible AC outlet
• near a modular telephone line 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 hand-
set’s range. If you have a choice of sev-
eral locations, try each to see which
provides the best performance.
Caution: The supplied AC adapter was
designed specifically for your ET-685.
Use only the supplied adapter.
Connecting to the Phone Lines
To take full advantage of the ET-685’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.
You can connect the ET-685 to the lines
in one of the these ways:
• connect two lines through a two-line
modular phone jack
• connect two lines through two one-
line modular phone jacks
• connect one line through a one-line
modular phone jack
Notes:
• Your phone connects directly to a
modular phone line jack. If your
phone wiring does not have a modu-
lar jack, you can update it using
jacks and adapters available at your
local RadioShack store. Or, you can
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 interfer-
ence (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.
On a Desk Top
1. Insert the two tabs at the bottom of
the wide end of the supplied bracket
into the base’s upper tab slots as
shown, then press down on the
bracket’s latches and insert them
into the clip slots.

2. To connect the phone to a two-line
phone jack, plug one end of the sup-
plied long two-line modular cord into
the TEL LINE 1/2 jack on the back of
the phone.
Note: If you connect the phone to a
two-line phone jack with a two-line
cord, do not connect another (third)
phone line to the TEL LINE 2 jack or
the phone will not operate properly.
Instead, you can connect another
phone device, such as a fax
machine or modem.
To connect the phone to two one-
line phone jacks, plug one end of
the supplied long two-line modular
cord into TEL LINE 1/2 and plug
another cord (not supplied) into the
TEL LINE 2 jack.
To connect the phone to a single
one-line phone jack, plug one end of
the supplied long modular cord into
the TEL LINE 1/2 or TEL LINE 2 jack.
Note: If you connect the phone to a
single one-line phone jack, avoid
pressing the unused line button or
you might hear feedback.
3. Plug the supplied AC adapter’s bar-
rel plug into the DC IN 9V jack on the
back of the base.

4. Route the adapter’s cord through
the strain relief slot on the bottom of
the bracket.
5. Plug the adapter into a standard AC
outlet.
6. Connect the phone cord(s) to the
modular phone line jack(s).
7. Raise the base’s antenna to a verti-
cal position.
On a Wall Plate or a Wall
Note: To mount the base directly on the
wall, you need two screws (not supplied)
with heads that fit into the keyhole slots
on the bottom of the bracket. Drill two
holes 315/16 inches apart. Then thread a
screw into each hole, letting the heads
extend about 5/16 inch from the wall.
1. Insert the two tabs at the top of the
wide end of the supplied bracket
into the base’s lower tab slots as
shown, then press down on the
bracket’s latches and insert them
into the clip slots.
2. To connect the phone to a two-line
phone jack, plug one end of the sup-
plied long modular cord into the TEL
LINE 1/2 jack on the back of the
phone.
Note: If you connect the phone to a
two-line phone jack with a two-line
cord, do not connect a cord to the
TEL LINE 2 jack or the phone will not
operate properly.
To connect the phone to two one-
line phone jacks, plug one end of
the supplied short two-line modular
cord into TEL LINE 1/2 and plug
another cord (not supplied) into the
TEL LINE 2 jack.
To connect the phone to a single
one-line phone jack, plug one end of
the supplied long modular cord into
the TEL LINE 1/2 or TEL LINE 2 jack.
Note: If you connect the phone to a
single one-line phone jack, avoid
pressing the unused line button or
you might hear feedback.
