D.Setting the tacking length
1. The tacking length can be set to between 3 and 43
mm in steps of 1 mm.
2. If not adding tacking, set the tacking length to "0". If
this is done, it will not be possible to set a value for the
offset.

that would make the difference between the
buttonhole length and the tacking length less
than 7 mm.

length setting.

E.Setting the offset
1. The offset can be set to between 0.5 and 2 mm in

If a tacking length that is outside the 0 - 3 mm range
is set, it will be set back to 1.5 mm automatically.
2. Press the "Up" button (L) or the "Down" button (K) to
set the desired offset.
* When the setting value is being changed, the
numerals appearing in the display will flash.
3. Press the ENTER button (N) to accept the new offset
setting.
* The display will stop flashing.
