Troubleshooting Procedures

®
MERLIN Plus Communication System parts may not be working properly.
Rather than call someone immediately, you can often determine the cause of
the problem yourself. Simply follow the step-by-step procedures outlined in
this section. Then, with the problem identified, you can either correct the
problem yourself or know from the chart who can help you correct it. If
you're having trouble with your MERLIN Plus system, locate the symptom on
the next few pages and perform the recommended action to isolate and correct
the problem. The symptoms and possible causes are listed on the contents
page of this section.
If you are unable to identify a problem, perform the General Test found on
the last page of this section before calling your equipment supplier for
assistance.
