found to comply with all applicable stan­dards.

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.

RISK OF ELECTRIC SHOCK.

DO NOT OPEN.

CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE
COVER OR BACK. NO USER-S ERVICE­ABLE PARTS INSIDE. REFER SERVIC­ING TO QUALIFIED PERSONNEL.

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 cordl ess phon e)
so you can still m ak e and re ce i ve calls if
there is an AC power failure.

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
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.
