TNI BLANK SETTING (TNI BLANK)

Set a sector and stop tuning operation in the bearing.
If a structure such as the mast is close to the radar antenna, automatic tuning operation may become unstable. In this
case, set a TNI blank in the direction of the structure in order to stabilize the tuning operation.
Only one TNI blank sector can be created. The TNI blank function operates in the relative bearing with the bow as the
