Troubleshooting
Problem Suggestion
I cannot dial out. First, try all the above suggestions.
Make sure there is a dial tone before dialing. It is normal if the handset takes a second or two 
to synchronize with the telephone base before producing a dial tone. Wait an extra second 
before dialing.
Make sure the telephone is set to the correct dial type (pulse dial or tone dial) for the service in 
your area. See Dial mode on page 10 to set the dial type.
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 not to dial out properly. If you cannot eliminate the background noise, 
rst try muting the handset before dialing, or dialing from another room in your home with less 
background noise.
