Troubleshooting
Problem Suggestion
There is noise
or interference
during a telephone
conversation.
My calls fade out or
cut in and out when I
am using the cordless
handset.
The handset may be out of range. Move it closer to the telephone base.
Appliances or other cordless telephones plugged into the same circuit as the telephone base
can cause interference. Try moving the appliance or telephone base to another outlet.
Other electronic products can cause interference to your cordless telephone. Try installing
your telephone as far away as possible from the following electronic devices: wireless routers,
radios, radio towers, pager towers, cellular telephones, digital telephones, intercoms, room
monitors, televisions, VCRs, personal computers, kitchen appliances, wireless routers, and
other cordless telephones.
Microwave ovens operate on the same frequency as your telephone. It is normal to experience
static on your telephone while the microwave oven is operating. Do not install this telephone
in the same outlet or near a microwave oven.
If your telephone is plugged in with a modem or a surge protector, plug the telephone (or
modem/surge protector) into a different location. If this solves the problem, re-locate your
telephone or modem farther apart from each other, or use a different surge protector.
The layout of your home or office might be limiting the operating range. Trying moving the
telephone base to another location, preferably a higher location for better reception.
Disconnect the telephone base from the modular jack and plug in a corded telephone. If calls
are still not clear, the problem is probably in the wiring or local service. Contact your local
service company (charges may apply).
If the other telephones in your home are having the same problem, the problem is in the wiring
or local service. Contact the local telephone company (charges may apply).
Do you have DSL service? If yes, you need to have a DSL filter installed at every telephone jack
that has a telephone connected to it. Contact your DSL service provider for filter information.
