Noise or static on the line
Interference is the most common cause of noise or static on a cordless phone. Here are some
common sources of interference:
• 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 uorescent light fi xtures (especially if
they give off a buzzing noise)
• other services that use your phone line,
like alarm systems, intercom systems, or
broadband Internet service
Here are some hints for when the static is...
on 1 handset or in 1 location:
on all handsets or in all locations:
- Check nearby for one of the common inter-
ference sources.
- Try moving the handset away from a sus-
pected 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 fi lter (see below).
Installing a line fi lter or DSL fi lter
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 fi lter or telephone line fi lter usually
solves this problem. The technician who installed your DSL service might have left some fi lters for
you; if not, call your DSL provider or look in any electronics store.
Plug the DSL fi lter into the telephone wall jack and plug
your phone’s base into the fi lter. Make a test call to make
sure the noise is gone.
Do you use a T-coil hearing aid?
If you have a hearing aid equipped with
a telecoil (T-coil) feature, the interaction
between the hearing aid and digital cordless
phones can cause noise in the handset. If
you have a T-coil hearing aid and you have
problems with noise on the line, try turning
on
T—coil
mode. Open the menu; select
Handset Setup
, and then select
T—coil
.
Using T-coil mode can shorten the
handset’s talk time; make sure to watch
the battery status and keep the battery
charged.
