 -Check nearby for one of the common 

interference sources.

 -Try moving the handset away from a 

suspected source, or try moving the 

suspected source so it’s not between 

the handset and the base.

 -Try moving closer to the base. There 

is always more noise at the edges 

of the base's range. If the handset 

displays an Out of Range message, 

you need to move closer to the base.

 -Check near the base for the 

source of interference.

 -Try moving the base away from a 

suspected source, or turn off the 

source if possible.

 -If the base has an adjustable 

antenna, try raising the antenna 

so it stands straight up.

 -If you have any service that uses 

the phone line, you might need a 

filter (see below).

Sometimes, broadband Internet 
services that use the telephone line 
can interfere with phones. One of 
these services−DSL−often causes 
static on telephones. A DSL filter or 
telephone line filter usually solves this problem. The technician who 
installed your DSL service might have left some filters for you; if not, 
call your DSL provider or look in any electronics store.
Plug the DSL filter into the telephone wall jack and plug your phone’s 
base into the filter. Make a test call to make sure the noise is gone.
