Please have Customers contact harman/kard

5、on directly at (516) 255-4545 to obtain warranty service. This service manual is being made available for units that are no longer under warranty, and products that are serviced outside the U.S. During testing, do not inject an audio signal frequency into the unit higher than 20kHz with no load. Pea

6、king in the output filter can cause the output voltages to exceed the filter capacitor voltage rating in this design. Normal audio program material will not have enough energy to cause problems. Avoid test tones above 20kHz. The following pages 8 - 27, reprinted from the DPR2005 owners manual, are a

7、ccurate for every feature and operation of both the DPR1005 and DPR2005 with the following exception: The only feature difference between the two models is located in the front accessory jacks. On the 2005 the Front-panel digital coaxial/optical jacks may be used as either Inputs or Outputs. Those s

8、ame jacks on the 1005 are for Inputs only; therefore there is also a missing indicator light for this function. For an accurate explanation of these jacks, refer to the DPR1005 owners manual.

When replacing a component identified with, use only the replacement parts designated, or parts with the same ratings or resistan

10、ce, wattage, or voltage that are designated in theparts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptablyinsulated from the supply circuit before retuming the product to the customer.Some semiconductor (solid state) devices ca

11、n be damaged easily by static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors andsemiconductor chip components.The following techniques should be used to help reduce the

12、 incidence of component damage caused by static electricity.1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge onyour body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharg

13、ing wrist strap device,which should be removed for potential shock reasons prior to applying power to the unit under test.2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, toprevent electrostatic charge build-up or ex

14、posure of the assembly.3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.4. Use only an anti-static solder removal device. Some solder removal devices not classified as anti-static can generate electrical chargessufficient to damage ES devices.5. Do not use freon-propelled c

15、hemicals. These can generate electrical change sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacementES devices are packaged with leads electrically shorted together by conductive fo

16、am, aluminum foil or comparable conductive material.)7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to thechassis or circuit assembly into which the device will be installed.Be sure no power is applied to the chassis or

17、 circuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing togetheror your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient t
