10.6 Lost Target
A target is declared a lost target when no data is received for three to five reporting intervals.
When this occurs, the target is marked with the (flashing) lost target symbol and the
indication “A-LOST” appears. Press the [CANCEL/CLEAR] 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 10.11.)

Confirming a lost target
1. Use the trackball to place the cursor where there is not ARPA target, marks nor lines.
2. Press the [CANCEL/CLEAR] key.
Note 1: You may also confirm a lost target by pressing [F2] and [5] (Lost Target).
Note 2: The AIS data transmission interval depends on other ship’s speed. For example,
the AIS data is transmitted every 10 seconds on a ship speed of 0-14 kt and every
two seconds on the ship speed of more than 23 knots. For details see the owner’s
manual of the AIS.
