INSTALLATION
We have designed your telephone to
conform to federal regulations, and
you can connect it to most telephone
lines. However, each device that 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 shown on the bottom of your
phone’s base.
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,
your phone might not ring. In rural ar-
eas, a total REN of three might impair
ringer operation. If ringer operation is
impaired, remove a device from the
line.
