ET-687 2-Line 900 MHz Digital Spread Spec. Cordless Phone
(430-0687) Installation Faxback Doc. # 51226
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.
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.
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: The supplied RadioShack adapter was designed specifically for
your ET-687. Use only the supplied adapter.
Connecting To The Phone Lines
To take 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.
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 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 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.

cord, do not connect a cord to the TEL LINE 2 jack or the phone
might not operate properly.
To connect the phone to two one-line phone jacks, plug one end of the
supplied two-line cord to the TEL LINE 2 jack, and plug another cord
(not supplied) into the TEL LINE 2 jack. Route both cords through the
strain relief slot on the bracket.

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.
2. Unfasten the plastic retainer strap and lift the battery pack out of
the compartment.
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.
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.
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 beeps
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 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 its ability to fully recharge, order a replacement battery
pack from your local RadioShack store (see "Replacing he Battery
Pack" in Faxback Doc. # 51229).
Setting The Dialing Mode
Set DIAL MODE on the back of the base for the type of service you have
(tone or pulse). If you are not sure which type you have, once the
battery pack is fully charged, do this test.
1. Set DIAL MODE to T (tone).
2. Press LINE 1 on the base. The line 1 indicator lights.
3. Press any number other than 0.
Note: If your phone system requires that you dial an access code (9,
for example) before you dial an outside number, do not press
the access code number either.
If the dial tone stops, that line has tone service.
If the dial tone continues, that line has pulse service.
4. Press LINE 1 to release the line, then repeat the test for Line 2.
If you have tone service on both lines, leave DIAL MODE set to T (tone).
If you have pulse service on either line, set DIAL MODE to P (pulse).
Setting The Ringer's Volume
At any time except during a call, press \/ or /\ to set the handset's
ringer volume. The phone rings at the selected volume.
To set the base's ringer volume, set RING VOL on the back of the base to
OFF, LO, or HI.
