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 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.
FCC STATEMENT
This telephone complies with Part 68
of
FCC Rules
. You must, upon re-
quest, provide the FCC Registration
Number and the REN to your phone
company. These numbers are located
on the bottom panel of the base.
Note:
You must not connect your
phone to any of the following:
coin-operated systems
party-line systems
most electronic key phone sys-
tems
Some cordless telephones operate on
frequencies that may cause interfer-
fence to nearby TVs and VCRs. To
minimize or prevent such interference,
the base of the cordless telephone
should not be placed near or on top of
TVs or VCRs. If interference is experi-
enced, moving the cordless telephone
farther away from the TV or VCR will
often reduce or eliminate the interfer-
ence.
