ï Dodge manoeuvres are accomplished by simply selecting the
desired course change using the course change keys
(
-1
,
+1
,
-10
or
+10
). Both the locked heading and locked apparent
wind angle are adjusted.
ï Once the hazard has been avoided, you can reverse the previous
course change, or return to the previous wind angle (
LAST WND?
).
Wind shift alarm
The wind shift alarm sounds, and the text
WINDSHIFT
is displayed, if a
wind shift of more than 15∞ is detected.
ï To cancel the alarm and retain the existing wind angle and new
heading, press
standby
and
auto
together.
ï Alternatively, to cancel the alarm and return to the previous heading,
either: adjust the locked wind angle using the
-1
,
+1
,
-10
and
+10
keys; or press
standby
to return to hand steering, steer onto the
required heading, and press
standby
and
auto
together to return to
Vane mode with the new apparent wind angle.
Using AutoTack in Vane mode
The automatic tack function, when used in Vane mode, turns the
vessel so that the locked apparent wind angle is changed to an
equal angle on the opposite bow.
Initially, the ST4000 Plus turns the vessel through the specified
tack angle (the factory default is 100°). Then the locked heading is
adjusted until the required apparent wind angle is achieved.
ï To tack to starboard, press the
+1
and
+10
keys together.
ï To tack to port, press the
-1
and
-10
keys together.
Note: If you use the AutoTack function in Vane mode, it is important to
check that the wind vane has been centred accurately when it was
installed.
