Offset function
If Offset mode = Locate, the time code counter displays the two locate points that define the
offset as “aa to bb,” where aa and bb are locate numbers ranging from 00 through 99. They
both default to 00 on power-on, since identical locate points result in no offset. Setting Locate
aa before or after Locate bb creates a positive or negative offset, respectively (offset = locate
bb - locate aa). To see the actual offset time, change the mode to Time Code and the time
code display will show the offset amount.

the ABS display to see the time offset, then change the ABS setting, the machine will follow the ABS
setting.
