North-up mode
The north-up mode paints target pips at their measured distances and in their true (heading sensor) directions from
own ship, north bearing maintained at the top of the screen. The heading line changes its direction according to the
ship’s heading. Requires heading signal.
If the compass fails, the presentation mode changes to head-up and the north marker disappears. A failure of the
heading sensor input will cause the heading readout to disappear, and the message "No heading available" or "Gyro
error" (message in red) appears at the lower right corner of the screen.

True motion mode
Own ship and other moving objects move in accordance 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. Note that true motion is not available on the 96 nm range scale. If
COG and SOG (both over the ground) are not available on TM mode, enter the set (tide direction) and drift (tide
speed) manually referring to the Tide Table.
If the position of the CCRP results in a part of the bearing scale not being distinguishable, that part of the bearing
scale is indicated with appropriate reduced detail.

A failure of the heading sensor input will cause the heading readout to disappear, and the message "No heading
