Troubleshooting
Problem Suggestion
There is noise
or interference
during a telephone
conversation.
My calls 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, and other cordless telephones.
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 doesn’t solve 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 ofce might be limiting the operating range. Try moving the telephone
base to another location, preferably a higher location for better reception.
Disconnect the telephone base from the telephone jack and plug in a corded telephone. If
calls are still not clear, the problem is probably in the wiring or local service. Contact the local
telephone 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).
If you subscribe to high-speed Internet service (Digital Subscriber Line - DSL) through your
telephone lines, you must install a DSL lter between the telephone base and the telephone
wall jack. The lter will prevent noise and caller ID problems caused by DSL interference.
Please contact your DSL service provider for more information about DSL lters.
