7.6Lost Target

A target is declared a lost target when no data is received for six minutes or five reporting intervals, whichever is the shorter. When this occurs, the target is marked with the (flashing) lost target symbol and the indication “LOST” appears. Press the [LOST TARGET] key to acknowledge the lost target, and the lost target disappears. However, the target which becomes a lost target is a activated target or a sleeping target within the lost target range (see paragraph 7.11).

2.Press the [5] key (LOST TARGET) to erase the lost target symbol and then press any key to close the menu.
