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.
