To carry out general troubleshooting procedures, use the following
chart. The left-hand column tells you what the main task is, while the
right-hand column describes the steps you must take to do the task.
These procedures are most effective if you carry them out in the
order they are ranked.
Steps to follow:
Ask the users for information about:
•The type of problem they have experienced (related to placing or
receiving calls, dropped calls or noise, or to problems with a
feature).
• How frequently the problems have occurred.
• Where the problems have occurred.
• How many portables are affected.
A problem may have been reported because of a misunderstanding
about how a feature works. Confirm that the person who reported a
problem understands the intended use and operation of any feature
in question.
To verify if the access lines have been programmed correctly, try the
host switch features on two or more portables.
Check that the programming recorded in the COMPANION 200
Programming Record is correct for the intended operation of the
system, and verify that the Configuration programming and
Administration programming has been entered correctly. See the
specific procedures for troubleshooting problems in this section.
Check the wiring and hardware connections. Refer to procedures in
"Troubleshooting the Controller hardware."
If hardware is defective, replace it.
If the problem requires expert advice, follow your company's
procedure for obtaining assistance.
