This radar system provides the automatic tune mode and the manual tune mode. The automatic tune
mode automatically adjusts the tuning of the transmitting frequency and the receiving frequency, and the
manual tune mode enables tuning to be adjusted by using the dial located on the operation panel.
Normally use the automatic tune mode. Only when the best tuning is not possible by the automatic tune
mode due to the deterioration of magnetron, use the manual tune mode.
The currently used tune mode is displayed in the area at the lower left of the display.
