SYSTEM SET UP
soft key. You will then see the
SYSTEM SET UP
MENU
.
3. Select
COMPASS SET UP
from the menu:
•

4. Press the
COMPASS SET UP
soft key. You will then see the

box.
The
COMPASS SET UP
box contains four items:
•
HEADING
= the current heading from the Smart Heading System (if
there is no heading figure displayed, check your compass
connections)
•
COG
= Course Over Ground heading from GPS (if connected)
•
SOG
= Speed Over Ground from GPS (if connected)
•
CORRECTED DEVIATION
= the amount of deviation corrected during
compass linearisation
At this stage, because you have not calibrated the Smart Heading System:
•
HEADING
and
COG
will differ
•
CORRECTED DEVIATION
will show dashes instead of a value
Note:
Press
ENTER
or
CLEAR
if you need to return to the
