- When the target cannot be received 5 times in the report intervals of the target
- When the target cannot be received for 6 minutes
Note:
- Conditions of the lost target on the FA-100 side are;
When the target cannot be received for 3 minutes 20 seconds or more, the
target becomes a lost target and when it is not received for another 3 minutes
20 seconds or more, it is deleted from the reception file.

It depends on the ship speed. For instance, the target becomes a lost target in
10 minutes while the ship is a halt, and in 7 seconds when the speed is 23 kt
or more. When there is no reception for another 400 seconds or more after it
becomes a lost target, the target is deleted from the reception file.
