In the north-up mode, target pips are painted at their
measured distances and in their true (compass)
directions from own ship, north bearing maintained up
of the screen. The heading line changes its direction
according to the ship’s heading.
If the gyrocompass fails, the presentation mode
changes to head-up and the north marker disappears.
Also, the HDG readout shows asterisks (***.*).
Own ship and other moving objects move in accord-
ance with their true courses and speed. In ground
stabilized TM, all fixed targets, such as landmasses,
appear as stationary echoes. In the sea stabilized TM
without set and drift inputs, the landmass can move on
the screen.
When own ship reaches a point corresponding to 50%*
of the radius of the display, it is automatically reset to a
point of 50%* radius opposite to the extension of the
heading line passing through the display center.
Resetting can be made at any moment before the ship
reaches the limit by pressing the [CU, TM RESET] key.
Automatic resetting is preceded by a beep sound.
If the gyrocompass fails, the mode is changed to the
head-up and the north marker disappears. The HDG
readout shows asterisks (***.*).
