INSTALLATION
We have designed your TAD to con-
form to federal regulations, and you
can connect it to most telephone lines.
However, each device that you con-
nect to the phone line draws power
from the line. We refer to this power
draw as the device’s ringer equiva-
lence number, or REN. The REN is
shown on the bottom of your TAD.
If you are using more than one device
on the line, add up all the RENs. If the
total is more than five, your phone
might not ring and your TAD might not
answer. In rural areas, a total REN of
three might impair ringer operation. If
ringer operation is impaired, remove
one of the devices from the line.
