Power voltage is dc 12V and fed with regulated dc power supply
from external power voltage jack (J901 on the POWER board).
•
Voltages and waveforms are dc with respect to ground under no-
signal conditions.

•
Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production toler-
ances.
•
Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler-
