In this case, execute the followingprocedure to reset the microcomputer and return itto normal condition.Unplug the power cord from the power outlet then,while holding the CD Open close (0) key de-pressed, plug the power cord again.After some time, the power will be switched off andreturn will be made to the initial status.CRPlease note that resetting the microcomputer clears thecontents stored in and it returns to condition when it leftthe factory.Note related to transportation and movementBefore transporting or moving this unit, carry out thefollowing operations.1Select the CD input2Press the 0key and take out the CD.3Ensure that “No Disc“ is displayed.4Wait for a few seconds, then set the powerOFF.CD6TUNER/BAND0Cautions AccessoriesRXD-NV500/NV6003CONTROLSTVVIDEO1VIDEO2CDTUNERTAPEFUNCTION%$VOLUME CONTROLCLOCK/LIGHTMUTECONFIRM/DEMOHOMEIR ON/STANDBYBANDINPUTDIRECTIONSETENTERCRREC P.CALL CURSOR67¢CRCR4CRCR1IR POWER&*()CR“CR£CR¢CRCRCRCR CRCR ¥CRCR »CRCRCRCRCRCRCRCRCRCR$Selector display/iconShows the operations selectedwith the remote control.%Menu/recording, editing selec-tion displayShows the selection menu, typeof recording or editing, etc.Input selection displayShows the status selected on themain unit or the input functionselected with the remote controlunit.&VOLUME CONTROL keys*CLOCK/LIGHT key(CONFIRM/DEMO key)HOME keyCRMUTE key“CRP.CALL/4 , ¢CRkeys£CRStop (7) key¢CRINPUT keyCR REC keyCRDIRECTION keyCRSET key¥CRENTER key»CRCURSOR keysCR6/BAND keyCRDisplayCRIR POWER () key(for U.S.A and CANADA)IR ON/STANDBY() key(for other countries)*The displayed information is variable depending on areas.30°30°30°30°CLOCK/LIGHTOperationCRWhen pressing more than one remote control keys suc-cessively, press the keys securely by leaving an intervalof 1 second or more between keys.After plugging the power cord of this unit, pressthe key of the remote control unit to turn thesystem ON. When the system is turned ON, pressthe key of the function to be operated.Operating range(approx.)Remote sensorRemote control sig-nal transmitter6 m6 mWhen the remote control unit is attached to themain unit, the power can be switched ON/OFFonly using the POWER () key on the main unit.Tolight the back light:(The back light is permanently on when the remote control unit isattached to the main unit with power on.)Press and hold the CLOCK/LIGHT key forabout 2 seconds.When the remote control unit is detached fromthe main unit, it is recommended to leave thedisplay back light off in normal condition inorder to save the battery power.Model : GRC-NV501 (for U.S.A. and Canada)Model : GRC-NV502 (for Europe and U.K.)Model : GRC-NV503 (for other countries)Infrared ray systemRXD-NV500/NV6004DISASSEMBLY FOR REPAIRElectric check of the main PCB1) Remove X29(A/3),X29(B/3), and X07(A/7) in order.(Remove the fan motor assy ,then assemble it on theheatsink1.)2) Connect GND between each PCB and the rear panelwith 4 alligator clip wires 2.Remove CD trayTake notice of the hooks with theCD tray panel, then remove theCD tray panel3.Disassemblythe remoconholder Take notice of the spring position,then disassemble the remoconholder4.X07(A/7)X07(D/7)2X29(B/3)X29(A/3)X29(C/3)Insulatorx1221223412The method that takes out a tray.1. Plug thin driver etc.to a square hole. And, press a rack gearin the direction of an arrow(1).2. Press the back side of a tray toward an arrow(2) with a fin-ger. At this time, draw a tray from a front side because atray appears on the side of a front.RXD-NV500/NV6005BLOCK DIAGRAMCLKPLL-CLKPLL-CEPLL-DOSDSTPLL-DATAS-LEVELDET-OUTDE-EMPHPOWERS.W.MUTEH.P.
