INSTALLATION
MOUNTING THE PHONE
You can place the ET-652 on a desk or
table, mount it on a standard wall plate,
or mount it 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
Caution: You must use a Class 2
power source that supplies 9
volts DC and delivers at least 300 mA.
Its center tip must be set to negative,
and its plug must fit the ET-652's
9V DC
jack. The supplied AC adapter meets
these specifications. Using an adapter
that does not meet the specifications
could damage the ET-652 or the adapt-
er.
Connecting the AC Adapter
1. Insert the supplied AC adapter's
barrel plug into the
9V
DC
jack on
the back of the phone.

2. Plug the adapter into a standard AC
outlet.
3. Route the adapter’s cord through
the strain relief slot on the bottom of
the phone.
Connecting to the Phone Lines
To take full advantage of the ET-652’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.
Notes:
• The line that connects the phone
jack to the phone company wiring
must be twisted-pair cable. Other-
wise, you might hear interference
(crosstalk) between the two lines.
• 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.
