•    Other cordless phones and 802.11 wireless routers that are used for 

home computer networks both use internal radios to communicate. 

The radios may interfere with one another. You can improve the per-

formance of your cordless phones and your router by:
a.  Positioning your new phone as far away as possible from any 

other existing cordless telephone system that is already installed 

in your home to avoid the two systems interfering with each other

b.  Positioning your telephone base as far as possible from your 

router, computer or any other computer devices.

c.  Selecting channels 4 through 10 for your router (refer to your 

router’s user manual for more information).

•    Other electronic products can cause interference to your cordless 

phone. Try installing your phone as far away from the following elec-

tronic devices as possible: wireless routers, radios, radio towers, 

pager towers, cell phones, intercoms, room monitors, televisions, 

personal computers, kitchen appliances and other cordless phones.

•    Microwaves operate on the same frequency as your phone. It is nor-

mal to experience static on your phone while the microwave oven 

is operating. Do not install this phone in the same outlet or near a 

microwave oven.

•    If your phone is plugged in with a modem or a surge protector, plug 

the phone (or modem/surge protector) into a different location. If this 

solves the problem, re-locate your phone or modem farther apart 

from one another, or use a different surge protector.

•    Relocate your phone to a higher location. The phone will likely have 

better reception when not installed in a low area.

•    If the other phones in your home are having the same problem, the 

problem is in your wiring or local service. Contact your local tele-

phone company (charges may apply).

•    If you subscribe to DSL service and if you hear noise during conver-

sations and/or your caller ID features are not functioning properly, 

install a DSL filter to the telephone line between the base unit and the 

telephone line jack. Contact your DSL provider to obtain a DSL filter

•   Disconnect the base unit from the telephone jack, and plug in a dif-

ferent telephone. If you still hear other calls, the problem is probably 

in your wiring or local service. Call your local telephone company.

•   Make sure the power cord is plugged in securely.
