This telephone has been tested and
found to comply with all applicable stan-
dards.
We recommend you record your phone’s
serial number here. The number is on
the bottom of the base.
Serial Number: __________________
Important Note: Cordless phones such
as your ET-687 require AC power to op-
erate. 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.
Your telephone operates on standard ra-
dio frequencies as allocated by the FCC.
Even though the security access-protec-
tion code prevents unauthorized use of
your phone line, it is possible for other
radio units operating on similar frequen-
cies within a certain area to unintention-
ally intercept your conversations and/or
cause interference. This lack of privacy
can occur with any cordless phone.
This symbol is intended to alert you to
the presence of uninsulated danger-
ous voltage within the product’s enclo-
sure that might be of sufficient
magnitude to constitute a risk of elec-
tric shock. Do not open the product’s
case.
This symbol is intended to inform you
that important operating and mainte-
nance instructions are included in the

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 op-
eration. 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 pro-
vide 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
• 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 lo-
cations, 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.
You can connect the ET-687 to the tele-
phone 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 modu-
lar 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 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.
