8. Another track may be selected by pressing the corresponding track

9. To clear all delays, press the ALL CLEAR button while in this page,

10. To exit the delay time mode, exit the Edit mode by pressing the
EDIT button (the EDIT LED will turn off) or press another toggle
function button. The RECORD-ENABLE buttons and LEDs will
return to normal functions.
Tip: If you need to advance a track so that it plays ahead of the others,
try setting all other tracks to a delay of, say, 85 ms (right in the
middle of the track delay's range). Now, you can adjust the delay
towards zero for those tracks which you want to move ahead,
while leaving you room to delay other tracks in the opposite
direction.
Note: Track Delay is a playback function, and so has no affect on a
track in record.
