2.2 Basic Operating Principles and Hints
Auto and Standby
Autopilotoperationhas beensimplifiedto asetof push-buttonkeys,
allofwhich are confirmedbya beep orbeeps.
Engagingtheautopilot couldnotbe easier.Simplysteer yourvessel
ontotherequired heading, presstheAUTObuttonand release the
wheel/tiller. Whenyouwant toreturn tomanualsteeringsimply
pressSTANDBYand regaincontrol.
Caution: Hand steering is not possible when your vessel is under
autopilot control. The pilot MUST be disengaged by pressing
STANDBY.It is the skippers responsibility to ensure that all crew
members are aware of this procedure.
CourseChanges
Coursechangesunder autopilotcontrol are madeusing the–1, +1,
–10and+10 keys. Thesekeysallow youtomake changesin 1°or
10°incrementsto port (–)and starboard (+).
Track
Trackmodetells theautopilot to steerunder thesupervisionof a
radioor satellitenavigationsystem. Therefore,the followingbasic
guidelinesshouldbeobserved before track isengaged:
• Alwayssteeryour vesselto within0.1nmof thetrack.
• Makesurethat thereare nonavigationalhazards eitherside ofthe
intended track.
• Maintainanaccurate log.
• Make regular plots to verify the computed position provided by your
positiontransducer.
• Maintaina properlookoutat alltimes.

TrackAdvance/Acceptance
Ifyournavigation receiver istransmittingwaypoint number and
bearingtowaypoint, a waypointalarmwill sound wheneveranew
targetwaypoint isselected.Theautopilot maintainsthe current
headingandautomatic track controlissuspended. Check thenew
bearingtowaypoint, makesure that itis safetoturn, andthenreturn
toautomatictrack controlby simply pressingthetrackkey. Thenew
targetwaypointis acceptedand the autopilotsteers yourvesselonto
the new heading.
Youmayfind thatthetidal offsetisvery differentonthe newbearing.
Therefore,it isadvisableto checkthe crosstrackerror(XTE)after a
coupleofminutes. Ifthe cross trackerror increases,makea course
adjustment(e.g.,10°) inthe direction ofthe arrow.Thishelps to
speeduptrack control correctionfor the newtidalvector.
Response
Therearethree responselevels.
Level1isthe defaultand suitablefor mostsituations. Thissetting
provides the best compromise between course-keeping accuracy and
power consumption.
Level2ensures tightercourse-keepingat theexpenseof increased
powerconsumptionand wearandtear duetoincreased pilotactivity.
Itis advisabletouse theminimum responsenecessarytoachievethe
desired course keeping accuracy.
Onlargervessels,level3 canimproveslow speedsteeringwhere
naturalyawdamping of thevessel is reduced.
Note: Level 3 is not recommended for use at planing speeds, or in rough
seas if a rate gyro transducer is not fitted.

Chapter3:EMC and ServicingGuidelines
3.1 Important information
AllAutohelmequipment andaccessories aredesignedto thebest
industrystandardsfor useinthe leisuremarineenvironment.
Theirdesignandmanufacture conforms to theappropriate
ElectromagneticCompatibility(EMC) standards,but good
installationis requiredtoensure thatperformance isnot
compromised.Althoughevery effort has beentakento ensure that
theywillperform underall conditions,itis importantto understand
whatfactorscould affect theoperationof the product.
3.2 Installation
Toavoidthe risk ofoperatingproblems, all Autohelmequipmentand
cablesconnectedto itshouldbe:
• Atleast 1m(3feet) fromany equipmenttransmittingorcables
carryingradiosignals, e.g.,VHFradios, cablesandantennas. Inthe
caseofSSB radios,the distanceshouldbe increasedto 2m(7ft).
• Morethan2m (6ft) fromthepath of aradarbeam. A radar beamcan
normallybeassumedto spread 20 degreesaboveand below the
radiatingelement.
• Theequipmentshould be suppliedfroma different batterythanthe
oneusedfor engine start.Voltagedrops below 10Vinthe power
supplytoour productscan cause theequipment toreset. Thiswill not
damagetheequipment, butwill cause theloss ofsomeinformation
and can change the operating mode.
• GenuineAutohelmcables shouldbe usedatall times.Cutting and
rejoiningthesecables can compromiseEMC performance andso
shouldbeavoided unlessdoing soisdetailed inthe installation
manual.
• Ifa suppressionferriteis attachedto acable,thisferriteshould notbe
removed.Ifthe ferritehas toberemoved duringinstallation itmust
bereassembled inthesame position.

3.3 Check Before Going to Sea
• Alwayscheck theinstallationbefore goingto seatomakesurethat it
isnot affectedbyradio transmissions,engine startingetc..
• Insomeinstallations, itmay notbepossible toprevent theequipment
frombeingaffected byexternal influences.Ingeneral thiswill not
damagetheequipment butcan leadtoit resetting,or momentarily
mayresultin faultyoperation.
3.4 Servicing and Safety
• Autohelm equipment should be serviced only by authorised
Autohelmservice engineers.Theywill ensurethat service
proceduresandreplacement parts usedwill not affectperformance.
Thereareno user serviceableparts in anyAutohelmproduct.
• Someproductsgeneratehigh voltages, and soneverhandle the
cables/connectorswhenpower is beingsuppliedto the equipment.
• Alwaysreportany EMCrelatedproblem toyournearest Autohelm
dealer.Wewill useany such informationto improveourquality
