Troubleshooting

•   You may be able to improve the performance of your 

cordless phone 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 phone. Try installing your phone as far 
away from the following electronic devices as possible: 
television sets, VCRs, or other cordless telephones.

•   Do not install this phone near a microwave oven or 

on the same electrical outlet. You may experience 
decreased performance while the microwave oven is 
operating.

•   If your phone is plugged in with a modem or a surge 

protector, plug the phone (or modem/surge protector) 
into a different location. If this doesn’t solve the 
problem, re-locate your phone or modem farther apart 
from one another, or use a different surge protector.

•   Relocate your phone to a higher location. The phone will 

likely have better reception when not installed in a low 
area.

•   If the other phones in your home are having the same 

problem, the problem is in your wiring or local service. 
Contact your local telephone company (charges may 
apply).

•  Disconnect the telephone base from the telephone jack, 

and plug in a different telephone. If you still hear other 
calls, the problem is probably in your wiring or local 
service. Call your local telephone company.

•   Make sure that the ringer is not turned off. Refer to the 

section(s) on ringer selection in this user’s manual.

•   Make sure the telephone line cord is plugged securely 

into the telephone base and the telephone jack. Make 
sure the power cord is securely plugged in.

•  The cordless handset may be too far from the telephone 

base.
