6.6.8. ANALOG BOARD SECTION

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.
