2.13 The CANCEL & CONFIRM KEYS.
The purpose of these keys is self explanatory in virtually all cases with the exception
of
SET UP
Menu entry and exit which, in each case, requires simultaneous operation
of the “
CANCEL
” and “
CONFIRM
” keys for a period of 5 seconds.
Normal operational functions can be summarised as follows:-

Execute
(Confirm)
or abort
(Cancel)
.
(ii)
COURSE AGAIN
(Resume Course) function and
Latched NFU

(iii)
+/- 1º, 5º & 10º
Step Course Changes :-
When the Autopilot is engaged (ON) in a normal operating mode (not
NEXT COURSE, U TURN, TRACK mode etc.) use of the
“TURN +”
or
“TURN –“
keys will produce permanent incremental Autopilot course
changes to Stbd (+) or Port (-).
Single press key operation (TURN) will order course changes in 1º
steps whilst continuous key operation will produce increasing course
change orders at the rate of approx 2 per second (2Hz) by an amount
defined by the length of time the key is pressed :-
•
First 5 steps in 1º increments.
•
Second 5 steps in 5º increments.
•
Thereafter in 10º increments.
In this manner, prolonged operation of the key will produce large course
change orders as required quickly and conveniently.
To use the +/-1º / +/-5º key function
:-
The Autopilot should be engaged
(ON)
steering the vessel on the
SET
COURSE
