• Power voltage is dc 14.4V and fed with regulated dc power

supply from ACC and BATT cords.

• Voltages are taken with a VOM (Input impedance 10 M

).

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-
