INSTALLATION
MOUNTING THE PHONE
You can place the ET–685’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 accessible 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 hand-
set’s range. If you have a choice of sev-
eral locations, try each to see which
provides the best performance.
Caution:
The supplied AC adapter was
designed specifically for your ET-685.
Use only the supplied adapter.
Connecting to the Phone Lines
To take full advantage of the ET-685’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-685 to the lines
in one of the these 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, you can
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.
On a Desk Top
1. Insert the two tabs at the bottom of
the wide end of the supplied bracket
into the base’s upper tab slots as
shown, then press down on the
bracket’s latches and insert them
into the clip slots.
