Noise or Static on the Line
The most common cause of noise or static on a cordless phone is interference: other wireless or electronic devices
can radiate energy that disturbs the radio signal between the base and the handset (much like overhead power lines
can cause static on your car radio). Some common household sources of interference are
•
electrical appliances, especially microwave ovens
•
computer equipment, especially wireless LAN equipment and DSL modems
•
radio-based wireless devices, such as room monitors, wireless controllers, or wireless headphones or speakers
•
large fl orescent light fi xtures (particularly ones that give off a "buzzing" noise)
•
other services that use your phone line, like alarm systems, intercom systems, or broadband Internet service
For static on only one handset or in a specifi c location:
•
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.
Installing a telephone line fi lter or DSL fi lter
Any broadband Internet service that uses your telephone
line might interfere with standard phones. The most common
type of these services, DSL, often causes static on your
telephone. Fortunately, an easy-to-install fi lter removes this
static from the line. Technicians who install DSL service
usually leave several fi lters for the customers; if you can't
fi nd them, call your DSL provider or look in any electronics
store.
Just plug the DSL fi lter into the telephone wall jack and then
plug your phone's base into the fi lter. Make a test call to
make sure the noise is gone.
For static on more than one handset:
•
Check near the base for the source of interference.
•
Try moving the base away from a suspected source,
or try turning off the source if possible.
•
If you have any services that might use your phone
line, see if you need a fi lter on the phone line.
