It is essential to note that the NT888G MK2 Autopilot has dual Type Approvals
covering conventional displacement vessels up to typically 30 knots and High Speed
Craft for speeds up to 70 knots.
The Control parameters are very different in each case therefore it is most important
that the correct vessel type (DISP or HSC) is entered in the Autopilot SET UP Menu
before Sea trials are attempted.
The displacement (DISP) or High Speed

HSC)
is
confirmed on the display. (i.e. 5 sec op. as above to change from DISP to
