WhentheMicroprocessorIC6001 and/orBack-up batteryB7751 arereplaced, readthefollowing
procedurecarefullyand proceedit.
[REASONS]
ThereisaRAMintheIC6001,whichisbackingup:
1.ProgrammeNavigation Data[SeeNOTE1]
2.TVTuningData
3.PGShifterAdjustmentData
4.Option SettingData
WhenIC6001 arereplaced,all abovelisteddatabecomenotavailable.
Thesedataisbackedup by usingthepowersourceof:
*ACConnected:ACPowersource
*ACDisconnected:Back-up Battery(B7751)&Back-up Capacitor(C7752)
[NOTE1]
Asforyourreference,withoutinsertingatapeintoaVCR,you canconfirmthattheNAVIdatathat
isbackup withIC6001 asshownin thefollowingsteps.
1.Indicatethe"NAVI"mark on theFrontInformation Panel.(PresstheMenu button and select
theoption,thensetthe"NAVI"toON mode.)
2.Turnon theServiceModeand press the"NAVI"button on theRemoteControllerinmore
than 5 seconds.The"NAVI"datalistisdisplayed on theMonitor.(Pressthe"MENU"button
