PC88 Internal Diagnostics
G-2
test will fail. If this test passes, however, even when there is nothing connected to the MIDI In
connector, there is a problem with the unit.
The
VGM Port Test
requires a VGM option to be installed. If no VGM option is installed, the test
will fail. If, on the other hand, there is a VGM option installed, the PC88 will use it to play Þve
test tones in sequence. You must press a button or keyboard key after each tone sounds in
order to advance to the next.
These tones are likely to be very loud and potentially destructive,
so be sure to set the PC88Õs volume slider to its minimum setting before running the diagnostic
tests.
You can adjust the volume slider after each tone begins to sound.

tests.
