setting is immediately saved.
26
+ and - keys
These keys are used to set the length of the overfeed
(fullness) for the active sequence or smooth sewing. Values
from 1.0 to 8.0 can be set. The overfeed length can only be
up to 1 mm smaller than the basic stitch length. If it is
further reduced, so is the basic stitch length.
These keys are also used to alter the special-function
parameters (see Set-up instructions).
"Off/on" key
Simultaneously pressing this key and a sequence key
deactivates the relevant sequence and the red LED over
the sequence key lights up. Doing this once more
reactivates the sequence; the red LED is switched off.
"Automatic change-of-direction" key
A series of sequences (program) is normally executed in
ascending order. After the final sequence control passes
back to the first sequence. If the "automatic
change-of-direction" key is operated, the green LED
above the key lights up and after the sequence has been
executed in ascending order it is then executed in
descending order, and so on.
"F" key
Pressing this key assigns edge-cutting functions to any
sequence and to "smooth sewing". The green LED above
the "F" key lights up to indicate that it has been activated.
7 Display segment
The display normally shows the length of the overfeed. The
values may lie between 1.0 and 8.0.
Error messages are issued in the event of an error, and
special functions displayed when the basic setting has
been changed (see Set-up instructions).
