2.3.3.5. Analog Board Section (Change from original page 81)

This chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending
upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone
line. 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, for example if you cannot communicate with
the H/S, trace that signal route locally with the following Check Sheet and locate the faulty point.
