2. Select [CURSOR/OWN SHIP
MARKS], then press the left button.
3. Select [EBL/VRM], then press the left
button.
4. Select [VRM OFFSET], then press the
left button.
5. Select [LINK EBL], then press the left
button. The offset EBL is now dis-
played with the linked VRM range ring.
6. Close the menu.

Target Trails

The trails of the radar echoes of targets can be displayed in the form of synthetic af-
terglow. Target trails are shown either relative or true and can be sea or ground stabi-
lized. True motion trails require a compass signal, and position and speed data. When
the range is changed, trails are continued for targets which were already displayed in
the previous range. Newly detected targets have no trail when first detected.
