INSTALLATION
Your TAD-764 conforms to federal reg-
ulations, 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 as the device’s
ringer
equivalence number
, or REN. The REN
is on the label on the bottom of the TAD.
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 (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-764 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 label on
the bottom of the TAD.
Note: You must not connect the TAD-
764 to:
• coin-operated systems
• party-line systems
• most electronic key phone systems
