<Notes>
1. WF21 is short for Waveform-21 .
2. Refer to SD-4 (SCHEMATIC DIAGRAMS-4) for the location
of each waveform on circuit.
3. SD-x : XY is short for Schematic Diagrams-x and each
socket's location, X=A to H, Y=1 to 5.
4. In the case that video outputs are not connected to video devices,
video signal output levels are doubled.
