Read This Before Installation
We have designed your Telephone Answering Device (TAD) to
conform to federal regulations, and you can connect it to most
telephone lines. However, each device, such as a telephone or
answering machine, that you connect to the telephone line
draws power from the telephone line. We refer to this power
draw as the device's ringer equivalence number, or REN. The
REN is on the bottom of your TAD.
If you use more than one phone or other device on the line, add
up all of the RENs. If the total is more than five (three in rural ar-
eas), your telephones might not ring. If ringer operation is im-
paired, 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 telephone company. Both numbers are on the bottom of
the TAD.
Note:
You must not connect your TAD to:
coin-operated systems
party-line systems
most electronic key telephone systems
