It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.

Great manual very clear copied. You are making an incredible job. I appreciate a lot the rapidity and your efficiency. Thanks a lot

Good pdf of the service manual for this unit. Includes disassembly instructions, full schematics, board layouts, parts lists and diagnostic information. Some information is in the pdf twice (single pages, and split pages), but that could be how it was originally generated by panasonic, or perhaps the idea is to make it eaiser to put onto 8.5 x 11" pages.
Information was exactly what I needed. Delivery was overnight (less than 12 hours) and I was happy with the process.

5 STARS for FAST DELIVERY, BEST PRICES and QUALITY PRODUCT. Item was exactly as described with superb resolution. Will definitely source all my future requirements from this website. Thanks a lot owner-manual.com!

Service bulletin # H/K2000-05 May 2000 To: All harman/kardon Service Centers Models: AVR300, AVR500 Subject: Volume Level Changes
Service Bulletin
Warranty labor rate: MAJOR repair
On early versions of the AVR300 or AVR500 the volume level may change by itself, or when the volume knob is tapped. This may happen on an occasional random basis and depends on where the volume control knob is positioned after a volume adjustment. During a running production change, new volume encoders were installed. In the event you receive an AVR300 or AVR500 with the complaint �The volume on my receiver changes by itself�, perform the following procedure: REPLACE VR901 VOLUME ENCODER 1) Remove the top cover, (14) Black Phillips screws. 2) Remove the (11) Black Phillips screws holding the plastic front panel to the chassis. 3) Remove the single Phillips screw on both right & left side of the chassis with a dual black ground wire. 4) Remove the volume, bass, treble and balance knobs by pulling them straight off. 5) Remove the single nut holding the volume encoder to the front panel. 6) Pull the loaded front panel off the chassis; cut any plastic cable ties necessary to fully disengage it 7) Lift and set the receiver on its right side for the remainder of the procedure. 8) Remove molex connector CN983 at the power switch; see Figure 1. 9) Pull the front panel as far away as the remaining connecting wires will allow. 10) Unsolder the connections at the rear of the front PCB to the volume encoder. 11) Using a �stubby� Phillips screwdriver, remove the (19) Black Phillips screws holding the front PCB to the front panel; two plated screws at the rear of the headphone jack also must be removed. 12) Pull the front PCB away from the front panel. 13) Remove and replace the volume encoder with h/k part# J32612050102; resolder the new encoder in place. 14) Replace the front PCB and reassemble the receiver in reverse order, following the instructions above. Replace all cable ties that were cut, and reattach any connectors that were unplugged. Make sure the two ground wires on both sides of the receiver are reattached. 15) Power up receiver, and test volume control to assure it no longer changes settings by itself, or when the volume knob is tapped.
