also have a corded phone that does
not need AC power to operate so
you can still make and receive calls
if there is an AC power failure.
• When AC power is lost, the phone
loses the security access-protection
code connection between the base
and the handset. When power is
restored, put the handset on the
base briefly to restore this connec-
tion so you can use the handset.
READ THIS BEFORE
INSTALLATION
We have designed your telephone to
conform to federal regulations, and you
can connect it to most telephone lines.
However, each telephone (and each de-
vice, such as an answering machine)
that you connect to the telephone line
draws power from the telephone line.
We refer to this power draw as the de-
vice’s ringer equivalence number, or
REN. The REN is on the bottom of your
telephone.
If you use more than one phone or other
device on the line, add up all of the
RENs. If the total is more than five (or
three in rural areas), your telephones
might not ring. If ringer operation is im-
paired, remove a device from the line.
Your telephone complies with Part 68 of
FCC Rules . You must, upon request,
provide the FCC registration number
and the REN to your telephone compa-
ny. Both numbers are on the bottom of
your telephone.
Note: You must not connect your tele-
phone to:
• coin-operated systems
• party-line systems
• most electronic key telephone sys-
tems
This equipment complies with the limits
for a Class B digital device as specified
in Part 15 of
FCC Rules . These limits
provide reasonable protection against
radio and TV interference in a residential
area. However, your equipment might
cause TV or radio interference even
when it is operating properly. To elimi-
nate interference, you can try one or
more of the following corrective mea-
sures:
• reorient or relocate the receiving
antenna
• increase the distance between the
equipment and the radio or TV
• use outlets on different electrical cir-
cuits for the equipment and the
radio or TV
Consult your local RadioShack store if
the problem still exists.
You must use shielded interface cables
with this equipment.
