INFORMATION
Weak or Hard to Hear Audio
If the 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 adjusting the volume of the earpiece ( see page E25 ) or the audio tone ( see page E26 ).
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.
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 florescent light fixtures (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 specific location:
For static on more than one handset:
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.
•
•
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 filter on the phone line.
