INSTALLATION
We have designed your phone to con-
form to federal regulations and you can
connect it to most phone lines. Howev-
er, each device that you connect to the
telephone line draws power from the
line. We refer to this power draw as the
phone’s
ringer
equivalence
number
(REN). The REN is on the bottom of
your phone.
If you use more than one phone or other
device on the line, add up all the RENs.
If the total is more than five (three in ru-
ral areas), your phones might not ring. If
ringer operation is impaired, remove
one of the devices from the line.
FCC STATEMENT
Your telephone complies with Part 68 of
FCC Rules
. Upon request, you must
provide the phone’s FCC registration
number and REN to your telephone
company. These numbers are shown on
the bottom of the phone.
Note: You must not connect your tele-
phone to:
• coin-operated systems
• party-line systems
• most electronic key phone systems
The telephone complies with the limits
for a Class B device as specified in Part
15 of
FCC Rules
. These limits provide
reasonable protection against radio and
TV interference in a residential area.
However, your telephone might cause
TV or radio interference even when it is
operating properly. To eliminate interfer-
ence, you can try one or more of the fol-
lowing corrective measures.
• Reorient or relocate the TV’s receiv-
ing antenna.
• Increase the distance between the
telephone and the radio or TV.
Consult your local RadioShack store if
the problem still exists.
