5. Why do I have static on my cordless phone?
Your cordless phone works as a miniature radio
transmitter and receiver. As such,it will pick up
stray signals caused by other nearby appliances
which emit radio signals and thus become a
source of interference.
Some sources in a home that may cause noise
and interference on a cordless phone are:
• other cordless phones
• fluorescent fixtures
• home appliances such as televisions,
refrigerators, microwave ovens,
home computers and baby monitors
In order to eliminate some of this interference
it may be necessary to relo cate the base unit of
the cordless phone to a different lo cation in your
house. This solves two problems. First, you are fur-
ther from the source of interference and secondly
the power adapter for the cordless phone will be
plugged into an outlet, which most likely is on a
different line than the appliance which is causing
the interference.
If the noise persists after relocating the base,
move closer to the base unit when talking on the
phone. If the noise disappears, then it is most like-
ly local interference being generated by a source
outside your home, or a source inside your home
strong enough to blanket your entire house such
as a baby monitor. If you find that the noise and
interference are equally strong throughout your
house, your cordless phone may require service.

4. Why do I sometimes have difficulty making a
connection even though I’m close to the base?
There are several possible causes for this condi -
tion. Please try the following solutions to see
where your problem lies.
First, make sure the base unit p ower adapter is
connected to a working AC outlet. Make sure
that you are within range of the base unit when
pressing the TALK button. If this works, then you
were trying to access the base from too great a
distance. Other cordless phones in your house
could be causing interference. Two or more
cordless phones may interfere with each other’s
security codes. If you have two or more cordless
phones in your house please disconnect all but
the phone which is giving you the Out of Range
signal. You can then reset the security codes by
using the following procedure.
To reset the security c ode, remove the handset
from the base. Remove the power cord from the
base for 30 seconds. Replace the power cord to
the base and replace the handset , making sure
the charge light comes on. Wait another 30 sec-
onds and the security c ode should be reset. Try
the phone after resetting the security code–it
should work fine. Your other cordless phones can
still be used but they should be moved further
apart or you may experience this problem again.
