We recommend you record your phone’s
serial number here. The number is on
the bottom of the base.

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.

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
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 th e 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.

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

• 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:

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.

The supplied RadioShack

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 throug h 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 modu­lar jack, you can update it using
jacks and adapters available at your
local RadioShack store, or h ave 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.

CONNECTING AND
CHARGING THE BATTERY
PACK

The ET-687 comes with a rechargeable
nickel-cadmium battery pack in the
handset but not connected. Before using
the phone, you must connect the battery
pack, then charge it for about 24 hours.

1. Press down and slide off the battery
pack compartment cover as shown.

2. Unfasten the plastic retainer strap
and lift the battery pack out of the
compartment.

9. Press and lift out the handset
holder, flip it over as shown, then
snap it back into place.

3. Plug the battery pack’s connector in­to the socket in the compartment
(the connector fits only one way),
then replace the battery pack and
fasten the retainer strap.

11

43-687 .fm Page 12 Fri day, August 13, 1999 11: 12 AM

4. Replace the cover.

To charge the battery pack, place the
handset on the base either faceup or
facedown. The CHARGE indicator on
the base lights.

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.

• If the battery pack becomes weak
during a call, the handset beep s ev­ery 3 seconds. If this happens, you
must recharge the battery pack be­fore you can make another call.

• Using a pencil eraser, clean the
charging contacts on the handset
and the base about once a month.

• 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 bas e until the low battery
indications (flashing line indicators
and beeping) app ear. Ot herwise, the
battery pack loses its ability to fully re­charge.

• The supplied battery pack should
last about one year. When it loses
its ability to fully recharge, order a
replacement battery pack from your
local RadioShack store (see
“Replacing the Battery Pack” on
Page 26).

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 p ack of the required size an d 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 replacem ent bat te ry
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 mut ilate 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.

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.

If you have tr ouble replacing the bat tery
pack, take the phone to your local Ra­dioShack store for assistance.

Important:

chargeable 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

THE FCC WANTS YOU TO
KNOW

In the unlikely event that your phone
causes problems on the phone lin e, the
phone company can temporaril y discon­tinue your service. If this happens, the
phone company attempts to notify you in
advance. If advance no tice is not prac ti­cal, 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, equi pment, 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 caus e 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 in terference goes
away, your phone is causing it. Try to
eliminate the interference by:

If you cannot eliminat e 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.

LIGHTN ING

Your telephone has built-in lightning pro­tection to reduce the risk of damage
from surges in telephone line and p ower
line current. This lightning protection
meets or exceeds FCC requirements.
However, lightning striking the tele­phone or power lines c an damage your
telephone.

Lightning damage is not common. Nev­ertheless, if you live in an a rea that has
severe electrical storms, we suggest
that you unplug your phone during
storms to reduce the possib ility 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
