many factors affect the range of a cordless
phone. In an open field, under ideal conditions,a
900 MHz cordless phone can have an effective
range of about 1200 feet.

Unfortunately, most cordless phones are used
under conditions that are anything but ideal. The
effective range of a cordless phone varies
because of environmental and other conditions.
Cordless phones and other 900 MHz devices ma y
cause interference which may limit the effective
range of your cordless phone. Changing the
channel may help.
Handset seems“dead”
Battery power has run out; return handset to base
and charge for at least 12 hours. If handset still
seems dead, unplug handset battery for 15 sec-
onds and plug back in. Then place handset back
on base for at least 5 minutes.
Memory dialing not working
Batteries need recharging; return handset to base.
Re-enter memory numbers.
Aluminum siding can also have a dramatic effect
on range.Try using your cordless phone in many
locations in and around your home .Each situa-
tion presents different conditions under which
the phone must work.

Frequently Asked Questions
Frequently Asked Questions
4.Why do I sometimes have difficulty making a
5.Why do I have static on my cordless phone?
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.
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.
First,make sure the base unit power 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.

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 relocate the base unit of
the cordless phone to a different location 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 b e
plugged into an outlet, which most likely is on a
different line than the appliance which is causing
the interference.

Frequently Asked Questions
(FAQ) can be found on-line at:
To reset the security code, 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 code 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 mo ved further
apart or you may experience this problem again.
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.
