ADJUSTMENT PROCEDURE
1.Power Supply Voltage adjustment
a. Connect the Digital Voltmeter to terminal "10" of the PCB (PS-25 or PS-26), and adjust VR101 for reading
+14V±100mV.
b. In the same manner with connection to terminal "13", adjust VR102 for reading -14V±100mV.
2. CLOCK RATE adjustment
Set the controls as illustrated bellow
