tions:  
5.  
6.  
Do not place this product on an unstable cart, stand or table. The product  
may fall, causing serious damage to the product.  
A. Use only the battery pack supplied with the unit or identical replace-  
ment.

cated on the marking label. If you are not sure of the type of power supply  
to your home, consult your dealer or local power company.  
C3. Do not expose batteries to heat or flame.

3.What is the range of my cordless phone?  
There is no way to easily answer this question as  
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.  
E-mail questions to:

Handset won’t work after power outage or  
disconnecting from AC power & reconnecting  
Return handset to base for thirty seconds to

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 seemsdead”  
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 Im 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 others  
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.  
Cobra Customer Service  
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.  
E-mail questions to:  
productinfo@cobraelec.com  
Cobra on the WorldWide Web:  
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.
