the AUTO-PUNCH button three times;
The display will read:

same time.
2. Put any and all tracks to be recorded on into record-ready by using

Since the Auto-group record function may be applied in several
different scenarios, here are two examples to help illustrate its use:
Example 1:
If channels 1 through 8 are record-enabled and the record group size
is 2, then the following will occur:
1st loop pass:
• Auto-punch in and out occurs on tracks 1 and 2;
• Tracks 1 and 2 record LEDs will be solid, while the LEDs of other
record-enabled tracks will be flashing.
2nd loop pass:
• Auto-punch in and out occurs on tracks 3 and 4;
• Tracks 3 and 4 record LEDs will be solid, while the LEDs of other
record-enabled tracks will be flashing.
3rd loop pass:
• Auto-punch in and out occurs on track 5 and 6;
