Analog Section (Fax Supported Models Only ) - Panasonic KX-MB2230JT Service Manual

12.3.12. Analog Section (Fax supported models only )

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 MicTX route begins at the microphone and the signal is output to the telephone line. The sig-
nal 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 Mic/Speaker,
trace that signal route locally with the following Check Sheet and locate the faulty point.
