Signal Route

This chapter provides the testing procedures required for the P.C.B. parts. A signal route to be tested is determined depending
upon purposes. The signal mainly flowing on this route is analog. You can trace the signal with an oscilloscope. The signal flow
on each route is shown in the Check Sheet here. If you find a specific problem in the unit, trace that signal route locally with the
following Check Sheet and locate the faulty point.
