This chapter describes two methods to solve the operational problems. The first relies on the OptraImage
443’s internal diagnostics. The second uses troubleshooting flowcharts and tables to isolate the problem. In
many cases, the internal diagnostics will help you to locate the source of the problem quickly. Use these
