Thismanualhasbeenproducedbyanewtechnicalinformationsystem.Thisnewsystemisdesignedtodeliver technicalinformationelectronicallythroughCDROMandinpapermanuals.AcodingsystemcalledICEhasbeen developedtolinkthetechnicalinformationtootherProductSupportfunctionse.g.Warranty.
Technicalinformationiswrittentosupportthemaintenanceandserviceofthefunctionsorsystemsonacustomers machine.Whenacustomerhasaconcernonhismachineitisusuallybecauseafunctionorsystemonhismachine isnotworkingatall,isnotworkingefficiently,orisnotrespondingcorrectlytohiscommands.Whenyourefertothe technicalinformationinthismanualtoresolvethatcustomersconcern,youwill findalltheinformationclassified usingthenewICEcoding,accordingtothefunctionsorsystemsonthatmachine.Onceyouhavelocatedthe technicalinformationforthatfunctionorsystemthenyouwill findallthemechanical,electricalorhydraulicdevices, components,assembliesandsub-assembliesforthatfunctionorsystem.Youwillalso findallthetypesofinformation thathavebeenwrittenforthatfunctionorsystem,thetechnicaldata(specifications),thefunctionaldata(howit works),thediagnosticdata(faultcodesandtroubleshooting)andtheservicedata(remove,installadjust,etc.).
ByintegratingthisnewICEcodingintotechnicalinformation,youwillbeabletosearchandretrievejusttheright pieceoftechnicalinformationyouneedtoresolvethatcustomersconcernonhismachine.Thisismadepossibleby attaching3categoriestoeachpieceoftechnicalinformationduringtheauthoringprocess.
