Isolating and Correcting Troubles

To isolate and correct a trouble:

FIRST: Determine if more than one voice terminal or basic Touch-Tone or rotary

telephone is experiencing the trouble.

SECOND: If the trouble appears on only one voice terminal or telephone, find the

symptom in the list below titled “A. Trouble on One Telephone.” The list includes

examples of problems categorized under each symptom. Turn to the tab divider for the

symptom and follow the procedures for your specific problem.

If the same problem appears on all or most telephones, find the symptom under the list

titled “B. Trouble on Several Telephones.” Turn to the tab divider for the symptom and

follow the procedures for your specific problem.

Refer to the “Functional Overview” or to the CIBs in this manual if you need more detail on

any component. For more information on programming voice terminals, refer to the User’s

Guide: Models 206, 410, and 820 and the administration manual that came with the feature

cartridge (optional) for your system.

The index will also help you find information on specific problems. If you cannot find your

problem in the symptom list or index, contact your equipment supplier.
