Troubleshooting
There is no dial tone.
•First try all the suggestions above.

jack on the telephone base and the corded handset.
•If the previous suggestions do not work, disconnect the telephone line from the console and connect it to a different telephone. If there is no dial tone on that telephone either, the problem is in your wiring or local service. Contact your telephone service provider.

•First try all the suggestions above.
•Make sure you have a dial tone before dialing. The corded handset might take a second or two to connect the console and produce a dial tone. This is normal. Wait an extra second before dialing.
•Make sure the telephone is set to the correct dial mode (pulse dial or tone dial) for the service in your area. Refer to Dial mode on page 44 to set the dial mode.
•If the other telephones in your building are having the same problem, contact your telephone service provider.
