IC DESCRIPTION IC, TMP47C443LDM-1B45(EL) Pin No.Pin NameI/ODescription 9 ADJUSTMENT 1.Tape Speed Adjustment Settings : Test tape :TTA 100 (Tape center) Test point :Phones Jack (J101) Adjustment location : SFR401 Dolby NR :OFF Super Bass :OFF Direction :FWD Tape selector :NORM Volume :MAX Method :Play back the test tape and adjust SFR401 so that the frequency becomes 3015 Hz 10 Hz. Then confirm WOW is less than 0.52%. 2.Dolby Level Adjustment Setting : Test tape :TTA 200 Test point :TP2(LCH), TP3(RCH), TP1(GND) Direction :FWD, REV Tape selector :NORM Dolby NR :OFF Super Bass :OFF Volume :MIN Adjustment points : Dolby level adjust point 1 , 2 , 3 , 4 , 5 , 6 Method :Connect 10F/16V coupling capacitors between test points and test equipment (connect the positive terminals to the test points). Short the Dolby level adjust point via solder as shown in the table so that the Dolby level becomes 100 mV 1.0 dB in both the forward and reverse directions.

How to use the test mode: Short the test land in the MAIN C.B. Auto-stop function is not detected by micro-computer while test mode is active. Note: Make sure that the test land is opened after the test mode is de-activated. (Auto-stop function is not available with shorted land condition.) 2. How to disassemble the circuit board. Removes the soldering part in the MAIN C.B (with the mark). Removes two screws.
