READ THIS BEFORE IN-
STALLATION
Your TAD conforms to federal regula-
tions, and you can connect it to most
telephone lines. However, each device
you connect to the phone line draws
power from the phone line. We refer to
this power draw is the device’s
ringer
equivalence number
, or REN. The REN
is on the label on the bottom of the TAD.
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 (or
three in rural areas), your phone(s)
might not ring and your TAD might not
answer. If ringer operation is impaired,
remove a device from the line.
FCC STATEMENT
Your TAD 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 label on the bottom
of the TAD.
You must not connect the TAD to any of
the following:
• coin-operated systems
• party-line systems
• most electronic key phone systems
