Troubleshooting
• You may be able to improve the performance of your cordless telephone by
installing your new telephone base as far as possible from any other existing
cordless telephone system that may already be installed.
• Other electronic products can cause interference to your cordless telephone.
Try installing your telephone as far away from the following electronic
devices as possible: television sets, VCRs, or other cordless telephones.
• Do not install this telephone near a microwave oven or on the same
electrical outlet. You may experience decreased performance while the
microwave oven is operating.
• 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, relocate your telephone or modem farther apart
from one another, or use a different surge protector.
• Relocate your telephone to a higher location. The telephone will likely have
better reception when installed in a high area.
• If the other telephones in your home are having the same problem, the
problem is in your wiring or telephone service. Contact your telephone
service provider (charges may apply).
