Inthis case, execute the following procedure to reset themicrocomputer and return it to normal condition.Please note that resetting the microcomputer clears the con-tents stored in and returns and to condition when it left thefactory.Set the POWER switch to ON (set to Standbymode). Then press the key, key and STOPkey in this order.SystemSpeakersDVR-8100KSW-8100 (Left speaker, right speaker, center speaker, surround speakers and subwoofer)Speaker model namesNote related to transportation and movementBefore transporting or moving this unit, carry out thefollowing operations.1Remove the disc from the unit.2Press the 6 key.3Wait a few seconds and turn the unit OFF.Manufactured under license from Dolby Laboratories.“DOLBY”, “Pro Logic” and the double-D symbol aretrademarks of Dolby Laboratories.“DTS” and “DTS Digital Surround” are trademarks ofDigital Theater Systems, Inc.FM indoor antenna (1)(T90-0882-08)Loop antenna (1)(T90-0896-08)Remote control unit (1)(A70-1600-08): X(A70-1601-08): ETBatteries (R6/AA) (2)Video cord (1)(E30-1427-05)SCART plug adaptor (1)(Europe and U.K. only)(E69-0012-05)Speaker cords (6)(E30-7265-08): RD(E30-7286-08): WH(E30-7285-08): VT(E30-7283-08): GN(E30-7269-08): GY(E30-7284-08): BLDVR-81002CONTENTS / ACCESSORIES / CAUTIONSCONTENTS / ACCESSORIES / CAUTIONS. 2DISASSEMBLY FOR REPAIR.3BLOCK DIAGRAM .3CIRCUIT DESCRIPTION.4ADJUSTMENT.14INTERCONNECTION DIAGRAM .15PC BOARD . 16SCHEMATIC DIAGRAM . 23EXPLODED VIEW .33PARTS LIST.34SPECIFICATIONS .Back coverContentsAccessoriesCautionsSYSTEMMAIN UNITSPEAKERDVT-8100DVR-8100KSW-8100SYSTEM CONFIGURATIONRadioFans.CN 收音机爱 好者资料库DVR-81003DISASSEMBLY FOR REPAIR / BLOCK DIAGRAMHow to open the tray if it does not come out.1.
