1.22 The FUNCTION key

The FUNCTION key works similar to the auto-
matic dialing feature on a telephone, playing back
controls settings just as they were registered. In-
stead of manually adjusting controls to set up for
navigation in a harbor, for example, you can have
the FUNCTION key do it for you.
Presetting the FUNCTION key
Eight target objectives are available and you can
assign three sets on the FUNC menu. The eight
objectives available are outlined in the table which
follows.
