tested is determined dependingtested is determined depending
upon purposes. For example, the handset TX route begins at the handset microphone and the signal is upon purposes. For example, the handset TX route begins at the handset microphone and the signal is

line. The signal mainly flowing on this route is analog. You can trace the signal with an oscilloscope. The signal flow on eachline. 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 withroute 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 H/S, trace that signal route locally with
the following Check Sheet and locate the following Check Sheet and locate
the faulty point.the faulty point.
