•U : B+ Line.
•V : B– Line.
•Voltages and waveforms are dc with respect to ground in playback mode.
•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal produc- tion tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc- tion tolerances.
•Circled numbers refer to waveforms.
•Signal path. E : PB j : REC
p : PB (Digital out)
l : REC (Digital in)
•Abbreviation
CND : Canadian model.
Note on Printed Wiring Boards:
•X : parts extracted from the component side.
•Y : parts extracted from the conductor side.
•¨ : Through hole.
•b : Pattern from the side which enables seeing.
