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