CONTRAST OF MISCELLANEOUS PARTSParts marked by NSP are generally unavailable because they are not in our Master Spare Parts List.The mark found on some component parts indicates the importance of the safety factor of the part.Therefore, when replacing, be sure to use parts of identical designation.Screws adjacent to mark on product are used for disassembly.Reference Nos. indicate the pages and Nos. in the service manual for the base model. NOTES:When ordering resistors, first convert resistance values into code form as shown in the following examples.Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%).Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).5 6 14 7 3R 5 01 R 05 6 2 156047k 0.51RD1/4PU JRD1/4PU JRN2H KRS1P K56 x 10147 x 103 R501R05614735.62kRN1/4PC F562 x 1015621PRV-LX1DW/KU/CA and PRV-LX1/KU/CA are constructed the same except for the following :PACKING SECTIONP15 - 7Operating InstructionsDRC1228 or DRC1258DRC1258(English/ French)P15 -16Packing CaseDHG2346DHG2458REAR PANEL SECTIONP23 - 4Rear PanelDNC1696DNC1709 Drive 1 Drive 2 Drive 1 Drive 2 (option)EXTERIOR SECTION (2/3)P19 - 6Drive Assy LX1DXX2532-DXX2532DXX2532No.1P19 - 11Silicone Spacer ADEB1600-DEB1600DEB1600No.2P19 - 12Heat SinkDNG1087-DNG1087DNG1087No.3P19 - 35ScrewBBZ30P060FMC-BBZ30P060FMCBBZ30P060FMCNo.4P19 - 36ScrewAMZ30P060FZK-AMZ30P060FZKAMZ30P060FZKNo.5FRONT PANEL SECTIONP25 - 14NSPTray FilterDEC2528-DEC2528DEC2528No.6P25 - 15Tray HolderDNV1038-DNV1038DNV1038No.7P25 - 16Tray SpringDBH1515-DBH1515DBH1515No.8P25 - 17Drive 2 Blind PanelDNV1040-Not usedNot usedP25 - 21Drive LensDNV1039-DNV1039DNV1039No.9P25 - 13NSPTray Panel 1DNV1037-DNV1037Not usedNSPTray Panel 2Not used-Not usedDNV1044No.10Tray Button 2Not used-Not usedDAC2110No.11Drive Lens Support PlateNot used-Not usedDEC2536No.12Drive 2 PanelNot used-Not usedDNV1045No.13Tray Panel 1 AssyDXA1961-DXA1961Not usedTray Panel 2 AssyNot used-Not usedDXA1962No.14ScrewVBA1034VBA1034VBA1034No.15ScrewNot used-Not usedBPZ20P060FZKNo.16 CONTRAST TABLEPart No.PRV-LX1/ KU/CARef.
