INSTALLATION
We have designed your phone to conform
to federal regulations, and you can con-
nect 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 on the bottom of the
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
phones might not ring. In rural areas, a to-
tal REN of three might impair ringer oper-
ation. If ringer operation is impaired,
remove a device from the line.
