Note: A mark entered in the replay mode is marked on the normal plotter display. To
enter a mark, press a numeric key ( 1 to 8 ). The corresponding mark or number is en-
tered on the ship’s track appropriate to the time marker when the cursor is turned on,
or at the own ship position when the cursor is turned off. When switching the display

ter a waypoint, press the
WPT key. The waypoint is entered at the same position as a
mark depending on cursor on/off. For the time marker, see section 11.5.
