Key scan and display circuit part 1) Description of key scan and display drive action As a following each part wave, “ HIGH” output is send out, by use of three terminals of MICOM No #5,6,7 by 6 msec intervals. This signal passes through input terminal of IC05 and is displayed to output terminal. At this time, the peak to peak voltage of rectangle wave is about 12V, the shape of output wave is like following.
