READ THIS BEFORE
INSTALLATION

Your ET-652 conforms to federal regula­tions, and you can connect it to most
telephone lines. However, each device
that you connect to the telephone line
draws power from the line. We refer to
this power draw as the device’s

If you are using more than one phone or

other device on the line, add up all the
RENs. If the total is mo re 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.

MOUNTING THE PHONE

You can place the ET-652 on a desk or

• out of the way of normal activities

Caution:

!

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
jack. The supplied AC adapter meets
these specifications. Using an adapter
that does not meet the specifications
could damage th e ET-652 or the a dapt­er.

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 on e line, y ou 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. Other­wise, 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 modu­lar jack, you can update it using
jacks and adapters available at your
local RadioShack store, or have the
phone company update it for you.

(RJ14W for a wall plate). The USOC
number of a single-line jack is
RJ11C.

Plug one end of the supplied two-line
