COG
If you have GPS or similar positioning data on your ST290 system and
you select the select COG screen, the digital display displays your course
over the ground. If such data is not available the display shows “ ---” .
Average heading
You can reset the average heading value to zero, by pressing the > button
for 3 seconds when the Average heading screen is displayed.
Locked mode
Locked mode enables you to define a fixed (locked) heading then
calculates any deviation from this locked heading. The digital display
shows heading information and a LOCK indicator. The pointer shows the
difference between the locked heading and the actual course being
steered, i.e. heading error (see Figure 3-4 ).
