INSTALLATION
We have designed your telephone to
conform to federal regulations, and
you can connect 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 phone might not ring. In rural ar-
eas, a total REN of three might impair
ringer operation. If ringer operation is
impaired, disconnect one of the devic-
es from the line.
Note:
Some cordless phones operate
at frequencies that might cause inter-
ference to nearby TVs and VCRs. To
minimize or prevent such interference,
the base of the cordless phone should
not be placed near or on top of a TV or
VCR.
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 on the
bottom of the phone’s base.
You must not connect your phone to
any of the following:
Coin-operated systems
Party-line systems
Most electronic key phone sys-
tems
Note:
Your telephone operates on
standard radio frequencies, as allocat-
ed by the FCC. Even though the ac-
cess-protection code prevents un-
authorized use of your phone line, it is
possible for other radio units operating
on similar frequencies within a certain
area to unintentionally intercept your
conversations and/or cause interfer-
ence. This lack of privacy can occur
with any cordless phone.
