NOTE:
1. WF21 is short for Waveform21 .
2. Refer to SD-6(SCHEMATIC DIAGRAM-6)
for the location of each waveform on circuit.
3. SD-x:XY is short for Shcematic Diagram-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.
