INSTALLATION
INSTALLING THE
HANDSET’S
ANTENNA
Insert the antenna into the
larger hole at the top of
the handset, then screw in
the antenna clockwise un-
til it is secure.
SELECTING A LOCATION
You can place the phone on a desk or
table, mount it on a standard wall plate,
or mount it directly on a wall. Select a lo-
cation that is:
• near an easily 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:
You must use a Class
2 power source that supplies
12 volts DC and delivers at
least 300 mA. Its center tip must be set
to positive and its plug must fit the
base's
DC 12V jack. The supplied adapt-
er meets these specifications. Using an
adapter that does not meet these speci-
fications could damage the base or the
adapter. You can connect your ET-689
to a 2-line modular telephone jack using
one of the supplied 2-line modular
cords. Or, you can connect your tele-
phone to two separate 1-line modular
telephone jacks using the supplied 2-
line modular cords.
Notes
:
• Your telephone connects directly to
a modular telephone line jack. If
your phone line jack is not a modular
jack, you can update the wiring
yourself, using jacks and adapters
available at your local RadioShack
store. Or, you can let the phone
company update the wiring for you.
• The USOC number of the two-line
jack to be installed is RJ14C (or
RJ14W for a wall plate jack). The
USOC number for a single-line jack
is RJ11C (or RJ11W for a wall plate
jack).
