The laser beam is emitted from thelocation shown in the figure. When checking the laser diode, be sure to keep your eyes at least 1 foot awayfrom the pickup lens when the diode is turned on. Do not look directly at the laser beam.CAUTION:Using controls and adjustment, or doing procedures other than those specified herein, may result inhazardous radiation exposure.2FL8380RadioFans.CN 收音机爱 好者资料库SAFETY PRECAUTIONSThis symbol is intended to alert the user tothe presence of uninsulated dangerousvoltage within the products enclosure thatmay be of sufficient magnitude to consti-tute a risk of electric shock to persons.This symbol is intended to alert the user tothe presence of important operating andmaintenance (servicing) instructions in theliterature accompanying the appliance.Caution:To prevent electric shock do not use this(polarized) plug with an extension cord, recep-tacle or other outlet unless the blades can befully inserted to prevent blade exposure.Attention: Pour prevenir les chocs electriques ne pasutiliser cetre fiche polarisee avec unprolongateur, une prise de courant ou une au-tre sortie de courant, sauf si les lames preventetre inserees a fond-sans en laisser aucunepartie a decouvert.HANDLING LASER PICKUPThe laser diode in the optical system of this player can be damaged by electrostatic discharge fromyour clothes or your body. Proper electrostatic grounding for service personal is required during servicing.BEFORE REPAIRING THE COMPACT DISC PLAYERPreparationHuman Body Grounding:Many of the components used in this compact disc player, including the laser pickup, are sensitive toelectrostatic discharge. Service personal should be grounded with an electrostatic armband (1 Mohm).Caution:Static charge on clothing does not escape through a body grounding wrist band.Be careful not to contact the pickup or electrical components with your clothing.Workbench and Tool Grounding:A properly-grounded electroconductive plate (1Mohm) or metal sheet should be fitted to the workbenchsurface. Tools and instruments (such as soldering irons and scopes) should be grounded to prevent ACleakage.Note: Laser diodes are so susceptible to damage from static electricity that, even if a static discharge doesnot ruin a diode, it can shorten its life or cause it to work improperly.WARNINGTo prevent fire or shock hazard, do notexpose the unit to rain or moisture.3FL83804Technical SpecificationsSignal FormatSampling Frequency44.1kHzHDCD ProcessingBurr-Brown PCM1732D/A ConversionDual 18-Bit Oversampling8 TimesDiscrete Analog Output SectionError CorrectionCIRC SystemFrequency Response20Hz 20kHz +0, 1dBTotal Harmonic Distortion (THD)97dBSignal-to-Noise Ratio97dBChannel Separation80dBLine-Level Output1.0V RMSDigital OutputCoaxGeneralPower Requirement120V/60HzPower Consumption20 WattsDimensionsHeight5.1 (129mm)Width17.3 (440mm) Depth15.2 (386mm) Weight16.7 lbs (7.6kg)Depth measurement includes knobs and buttons.Height measurement includes feet and chassis.All features and specifications are subject to change without notice.Harman Kardon is a registered trademark, and Power for the digital revolution is a trademark, of Harman Kardon, Inc., HDCD, High Definition Compatible Digitaland Pacific Microsonicsare either registered trademarks or trade-marks of Pacific Microsonics, Inc., in the United States and/or other countries.
