The GA-100CD has keys that function differently
depending on whether they are pressed briefly (less
than half a second) or pressed and held (more than
half a second). In this manual, instructions to “press
the key” or, for example, “press
VSA ” refer to brief
presses, while instructions to “press and hold the
key” or, for example, “press and hold
OSC ” refer to
long presses.
The CD Trainer Control LCD usually shows the
elapsed track time, remaining track time or total
remaining CD time. In this manual, this status is
referred to as the “time display.”
