INSTRUCTION MANUAL
4.5 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.
