Troubleshooting
• Test a working telephone at the same telephone jack. If
another telephone has the same problem, the problem 
is in the telephone jack. Contact your local telephone 
company (charges may apply).
• The telephone line cord might be malfunctioning. Try
installing a new telephone line cord.
I cannot dial 
out.
• First, try all the above suggestions.
• If the other telephones in your home are having the
same problem, the problem is in the wiring or local 
service. Contact your local telephone company (charges 
may apply).
• Eliminate any background noise. Noise from a television,
radio, or other appliances may cause the telephone 
to not dial out properly. If you cannot eliminate the 
background noise, first try muting the telephone before 
dialing, or dialing from another room in your home with 
less background noise. 
• Other electronic products can cause interference to your
telephone.
• 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.
• If the other telephones in your home are having the
same problem, the problem is in the wiring or local 
service. Contact your local telephone company (charges 
may apply).
My calls fade out 
or cut in and out 
when I am using 
the telephone.
I hear other 
calls when using 
the telephone.
• Disconnect the telephone base from the telephone jack.
Plug in a different telephone. If you still hear other calls, 
the problem is probably in the wiring or local service. 
Call your local telephone company.
