Note
• After replacement of the magnetron, perform rough tuning while the image is stable after setting
the radar to the Standby state for 20 to 30 minutes as the preheating time, operating the radar
from the short pulse range, and shifting the operation to the long pulse range sequentially.
• This operation is disabled when the Radar Interswitch is set to the Slave mode.
• Not displayed when the solid-state radar antenna is connected.
