Troubleshooting
Perform operation checks on the radar equipment at regular intervals, and if any abnormality is detected, immediately start inspection on the abnormality. In particular, be careful of the high voltages during operation checks, and caution should be taken to avoid incorrect or carelessness measurement which can cause trouble. Take notes of the check results that are very useful as reference during the next operation check.
