FAULT FINDING

In case of semiconductor circuits, it is deemed that there are few cases in which the used semiconductor
devices have inferior quality or performance deterioration except due to insufficient design or inspection
or by other external and artificial causes. In general, the relatively many causes are disconnection in a
high-value resistor due to moisture, a defective variable resistor and poor contact of a switch or relay.
Some troubles are caused by defective parts, imperfect adjustment (such as tuning adjustment) or
insufficient service (such as poor cable contact). It will also be effective to check and readjust these points.

9.1.1 List of Alarms and other Indications

The system automatically recognizes an internal alarm and displays the alarm message. If an event which
is not trouble but must be reported to the operator occurs, the system notifies the operator of the event.
This section gives the list of alarms displayed by the system and other display lists.
