Serial Number: __________________
READ THIS BEFORE 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 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 phone might
not ring. In rural areas, a total REN of three might impair ringer op-
eration. If ringer operation is impaired, remove a device from the
line.
FCC STATEMENT
This telephone complies with Part 68 of FCC Rules. You must,
upon request, provide the FCC registration number and the REN
to your phone company. These numbers are on the bottom of the
base.
