Troubleshooting

I get noise,

If you subscribe to high-speed internet

static, or weak

 

service (Digital Subscriber Line - DSL)

signal even

 

through your telephone line, you must

when I’m near

 

install a DSL filter between the telephone

the telephone

 

base and the telephone wall jack. The filter

base.

 

will prevent noise and caller ID problems

 

 

caused by DSL interference. Please

 

 

contact your DSL service provider for more

 

 

information about DSL filters.

 

You may be able to improve the

 

 

performance of your cordless phone by

 

 

installing your new telephone base as far

 

 

as possible from any other existing cordless

 

 

telephone system that may already be

 

 

installed.

 

Other electronic products can cause

 

 

interference to your cordless phone. Try

 

 

installing your phone as far away from the

 

 

following electronic devices as possible:

 

 

television sets, VCRs, or other cordless

 

 

telephones.

 

Do not install this phone near a microwave

 

 

oven or on the same electrical outlet. You

 

 

may experience decreased performance

 

 

while the microwave oven is operating.

 

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.
