The DC voltage is an actual reading measured with a high
impedance type voltmeter. The measurement value may
vary depending on the measuring instruments used or on
the product. Refer to the voltage during PLAY unless other-
wise specified; The value shown in (
) is the voltage mea-
sured at the moment of STOP.
