Troubleshooting
Problem Suggestion
The telephone does not
ring when there is an
incoming call.
Test a working telephone at the 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.
Re-install the battery and place the cordless handset in the telephone base.
Wait for the cordless handset to synchronize with the telephone base. Allow up to one minute
for this to take place.

I cannot dial out. First, try all the above suggestions.
Make sure there is a dial tone before dialing. It is normal if the cordless handset takes a second
or two to synchronize with the telephone before producing a dial tone. Wait an extra second
before dialing.
Makes sure the telephone is set to the correct dial mode (pulse dial or tone dial) for the
service in your area. Refer to the Dial type section of this user’s manual (page 13) to set the
dial mode.
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 cordless handset before dialing, or dialing from another room in your home with
less background noise.
