Both the locked heading and locked apparentwind angle are adjusted.ï Once the hazard has been avoided, you can reverse the previouscourse change, or return to the previous wind angle (LASTWND?).Wind shift alarmThe wind shift alarm sounds, and the text WINDSHIFTis displayed, if awind shift of more than 15∞ is detected.ï To cancel the alarm and retain the existing wind angle and newheading, 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 +10keys; or press standby to return to hand steering, steer onto therequired heading, and press standby and auto together to return toVane mode with the new apparent wind angle.Using AutoTack in Vane modeThe automatic tack function, when used in Vane mode, turns thevessel so that the locked apparent wind angle is changed to anequal angle on the opposite bow.Initially, the ST4000 Plus turns the vessel through the specifiedtack angle (the factory default is 100°). Then the locked heading isadjusted 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 tocheck that the wind vane has been centred accurately when it wasinstalled.
