INSTALLATION
Your system conforms to federal regu-
lations, and you can connect it to most
telephone lines. However, each de-
vice that you connect to the phone line
draws power from the line. We refer to
this power draw as the device’s r
inger
equivalence number, or REN. The
REN is on the bottom of the system.
If you are using more than one phone
or other device on the line, add up all
the RENs. If the total is more than five
(three in rural areas), your phone
might not ring or your system might
not answer. If ringer operation is im-
paired, remove a device from the line.
FCC STATEMENT
Your system complies with Part 68 of
FCC Rules. You must, upon request,
provide the FCC registration number
and the REN to your phone company.
Both numbers are on the bottom of
your TAD.
Note: You must not connect your sys-
tem to:
• coin-operated systems
• party-line systems
• most electronic key phone sys-
tems
Your system complies with the limits
for a Class B digital device as speci-
fied in Part 15 of
FCC Rules. These
limits provide reasonable protection
against radio and TV interference in a
residential area. However, your TAD
might cause TV or radio interference
even when it is operating properly. To
eliminate interference, you can try one
or more of the following corrective
measures:
• Reorient or relocate the receiving
antenna of the radio or TV
antenna.
• Increase the distance between the
TAD and the radio or TV.
• Use outlets on different electrical
circuits for the TAD and the radio
or TV.
Consult your local RadioShack store if
the problem still exists.
