AMC CDM7 LASER ADJUSTMENT PROCEDURE ADJUSTMENT POINTS DIAGRAM: LASER CURRENT ADJUSTMENT: The integrated circuitry used in the CD PCB eliminate the need for most adjustments by incorporating self adjusting circuitry.However, when parts in the servo circuitry or CD mechanism are replaced, a laser current adjustment should be performed. Please follow the steps below: 1. Insert the test disc (Sony Type 4, YEDS 18). 2. Make sure the power is turned OFF. 3. Connect a high impedance voltmeter across the test points labelled LASER ADJ. 4. Turn the power ON and press the Play button. 5. When track 1 starts playing, adjust R127 to 50mv +/-2mV specification.
