When chasing, it may take some time before chase

8.3 Machine offset

It is sometimes necessary to offset a slave unit in the
chain relative to the master unit. This offset can be
set to sample accuracy to a maximum value of two
hours.
NOTE
This offset is unrelated to timecode offset and refers
only to the machine offset when synchronized to
other DTRS units.

move the cursor to the different fields. The
OFFSET key can also be used as a right cursor
key.
See 4.3.5, ""Left" and "right" keys" for details
of setting values in a time field.
5 You can also change the sign of the offset value
between by moving the cursor to the sign.

If you change an offset value (timecode or ABS), any
punch points, location memories, etc. will be invali-
dated. For example, if you change the offset to
00:30:00.00 (30 minutes) from 00:00:00.00 (no off-
set), a punch point which was previously at
00:33:00.00 (33 minutes into the tape) will still have
the same value (00:33:00.00), but will now be only 3
minutes into the tape.

To cancel machine offset, simply set the offset value
to 00:00:00.00.
