Weak or Hard To Hear Audio
If a caller’s voice sounds weak or soft, the signal might be blocked by
large metal objects or walls; you might also be too far from the base,
or the handset’s battery may be weak.
 Try moving around while you’re on a call or moving closer to the
base to see if the sound gets louder.
 Make sure the handset’s battery is fully charged.
 Try adjusting the earpiece volume.
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 florescent light
fixtures (especially if
they give off a buzzing
noise)
 other services that
use your phone line,
like alarm systems,
intercom systems, or
broadband Internet
service
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, 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.
