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!!!!!!!!
;
You can fully trust on this one!
All the schematics are very crear an in one piece per page

Description
Dot matrix LCD driver power supply. LCD driver power supply. Internal logic power supply. Input/output singnal synchronization. When "L", a forced LCD OFF operation is performed, and SIGn & COMn output the unselected waveform. Initial state is set when "L". "H" if there is KEY data, "L" if there is none. KEY data can be read in respective of the state of this pin, CMOS output. DATA shift clock. DATA is read on rising edge, and output on falling edge. Performs input of commands, key data etc., and key data output. Input is performed from the MSB on the rise of the shift clock, and the first 8 bits are recognized as a

Strobe input, DATA input is unabled when "H". Command processing performed on a fall. Oscillation circuit. KEY scanninng key data input. KEYscanning key source output. Dot matrix LCD segment output. Dot matrix LCD common output. 1. Dolby NR Adjustment Settings : � Test tape : TTA�200 � Test points : TP1(Lch), TP2(Rch) � Adjustment location : SFR201(Lch), SFR202(Rch) Method : 1. Play a Dolby NR tape and adjust SFR201 and SFR202 so that the Lch (TP1) and Rch(TP2) levels are 300 ± 5mV. 2. Adjust the level in the forward running direction, and then check in the reverse direction. If the level drifts from the specification, perform readjustment.
