Radio Shack ET-651 Telephone User Manual

Read This Before Installation
We have designed your ET-651 to con-
form to federal regulations, and you can
connect it to most telephone lines. How-
ever, each telephone (and each device
such as an answering machine) that you
connect to the telephone line draws
power from the line. We refer to this
power draw as the phone’s
ringer equiv-
alence number
, or REN. The REN is on
the bottom of your phone.
If you use more than one telephone or
other device on the line, add up all the
RENs. If the total is more than five, your
telephones might not ring. In rural areas,
a total REN of three might impair ringer
operation. If ringer operation is impaired,
remove one of the devices from the line.
FCC Statement
Your ET-651 complies with Part 68 of
FCC Rules. You must, upon request,
provide the FCC registration number
and the REN to your telephone compa-
ny. Both numbers are on the bottom of
the phone.
Note:
You must not connect your ET-
651 to any of the following:
coin-operated systems
party-line systems
most electronic key phone systems
PREPARATION
Connecting the Handset
Plug the supplied coiled handset cord
into the jacks on the handset and the left
side of the phone.
Connecting to the Phone Lines
To take full advantage of the ET-651’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.
The USOC number of the two-line
jack to be installed is RJ14C. The
USOC number of a single-line jack
is RJ11C.
