INSTALLATION
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 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
total REN of three might impair ringer
operation. If ringer operation is impaired,
remove a device from the line.
