To recall a memorized hot cue point
Hot cue points A, B, and C are recorded automatically on the memory
card. If hot cue points are recorded at the time a disc is inserted, the
HOT CUE buttons A, B, C will flash green or orange. To call up one of the
recorded hot cue points, press the corresponding button A, B, or C. The
flashing green or orange indicator will light steadily (sound will not begin
instantly when the call is made). If you have no need of calling one of the
hot cue points, press the HOT CUE REC MODE button. The indicators
will change to red, and the hot cue setting mode will be enabled. (To
subsequently call up one of the hot cue points previously recorded on
the memory card, remove the disc or memory card and reinsert it so that
the A, B, and C buttons flash once again. Then press the desired flashing
button).
As hot cues are global for the CD, if you want to load a memory point to a hot cue, you need to press the CALL button, then record that cue to a hot-cue as needed.
