3、or identifying the old type and new type for convenience on service system. Check the model name as follows. Of the three types, only the appearance of the “DD-3” is different. Identify the “DD-3” or the “DD-3A or DD-3B” by the shape of the adapter jack as shown in the following figure. The appearan

Set the VR3(D.TIME knob) to the min (fully-ccw). b. Connect the oscilloscope to R26(1k ohm resister) or pin 5 (or pin 6) of IC3 (HD14066BP). c. Adj

33、ust RT1 (1kB potentiometer) on MT BOARD for T=12.50.5uS(Fig.1). In some types of products, turning the RT1 continuously clockwise may once go outside the adjustable range and reenter there. Therefore, at the start, turn the RT1 fully counter-clockwise, then slowly turn it clockwise. When the adjusta
