NOTE
If potentiometer A5R2 requires adjustment, perform measuring circuit alignment
after power supply A5 alignment is complete.
(4) Connect digital voltmeter (+) to points listed in table 4-5 and check that digital
voltmeter reads within minimum and maximum values for each test point. If voltage is
not within minimum and maximum values, replace power supply board A5.
