I would not plug this machine in without finding a manual like this. In addition to setup and normal operating instructions, it has troubleshooting flowcharts, diagrammed mechanical adjustments, and schematics to beat the band. The tech I hand it to would be thrilled to find solder side PCB diagrams with component outlines superimposed, pinouts for every IC chip, and line drawings of transistors, with labeled legs.
As for printing quality, this may be a copy of a copy, but even the finest print when enlarged is very legible. There is a bit of grayed print over a few pages, as if a wet page were placed over it, but the print is still very legible. If you could borrow an original manual and get it printed and bound for 4 to 6 times the cost, you could get better quality. In that case you wouldn't be here. For price, utility, and availability I am rating this manual highly.

I PURHASED THIS PRODUCT BECAUSE I WAS HAVING PROBLEMS WITH MY CDR20 HARMAN KARDON RECORDER. WHICH I PURCHASED NEW 12 YEARS AGO. AFTER REVIEWING THE MANUAL, I WAS ABLE TO ADJUST THE TENSIONER IN THE SYSTEM. WORKS LIKE A CHAMP!.
SAVED ME AT LEAST 100.00 WHICH WAS WHAT A SERVICE REPAIR STATION WANTED. GREAT MANUAL EASY TO READ. SPECIALLY AFTER I PRINTED THE PAGES WHICH DEALT WITH MY RECORDER. THANKS A LOT!!!!!!!!

Service bulletin # H/K9901 Rev1 November 2002 To: All harman/kardon Service Centers Models: FL8350/FL8550 Subject: �No disc� reading in display
Service Bulletin
Warranty Labor Rate: Major Repair
When a CD is in the carousel at the play position, Infra red light emitted by IR LED D3 is reflected onto IR Photo sensor D2. D3 and D2 are on the PCB located underneath the carousel. When the amount of IR light received by D2 is insufficient, D2 will not saturate and the display will read �No disc�. In the event you receive an FL8350 or FL8550 with the complaint: Display reads �No disc� but a disc is in the tray, perform the modification as listed below: 1) Lay the unit on a padded surface. 2) Remove the (7) Black Philips screws holding the Top Cover on; remove cover. 3) Lay unit on its side and remove (5) Black screws on bottom which hold front panel to chassis. 4) Lay unit upright, remove (2) Black screws at top front section holding front panel to the front tray retainer brackets. 5) Pull front panel away, cut plastic cable ties if necessary, and lay the front panel face down on the table. 6) Remove (4) tray retainer brackets, (1) Plated screw each. (Bracket on left side may have a ground terminal). 7) Pull the carousel tray up and out of the unit; turn upside-down to expose the sensor board. 8) Remove the (2) Plated screws holding the sensor board to tray. 9) Lift the board and unplug either molex connector CN1 or CN2 to be able to turn board upside-down. 10) Locate R1 and change from a 470W to a 750W resistor - h/k part# 1007-501316-000. 11) Locate R2 and change from a 750W to a 470W resistor - h/k part# 1004-701316-000. Alternately, the two above parts may just be �swapped�, as this will result in the correct values. 12) Locate D3 and replace with new infra-red LED - h/k part# 3100-204000-002.
REASSEMBLY: 13) Replace sensor board, screws, and CN1 or CN2 connectors. 14) Turn the carousel tray over and replace back in the track; tray must be positioned all the way at the rear of the unit. When placed correctly, tray should not glide back & forth on the track. 15) Replace and attach the (4) tray retainer brackets with single screws - ground wire (if present) is re-attached to left front bracket. 16) Replace the front panel, both with the (5) bottom screws and the (2) screws at the top. Note: Make sure any washers that were present between the various brackets and the chassis are reinstalled. Replace cable ties as necessary. 17) Test the player by inserting one or more compact discs, assure unit reads discs in all slots. 18) Locate MCU board, which is mounted vertically on right side of unit. Connect DC Multimeter to Pin 8 (gray wire) of CN705 (10 pin plug, labeled 'DSNS'), and Pin 2 (red wire) of CN701 (2 pin plug). While playing a disc, DC Multimeter reading must be between 4.7 V and 5.0 V. 19) Replace top cover and screws.
