In this case, the steps of procedure to be taken up to step 2) are

Once the sewing screen is displayed, sewing can be started.
If one of the bobbins is empty, the device winds thread on the bob-
bin. After the device completes winding of the bobbin, it enters the
standby state waiting for the moment to change the bobbin.
Special care should be taken when using a bobbin
that has been already wound with thread, since the
preset number of stitches may not be sewn in its en-
tirety (i.e, bobbin thread may run out during sewing)
if the quantity of thread wound on the bobbin is not
sufficient.
It is recommended to avoid the use of bobbin which has been used
halfway or the bobbin wound with unknown quantity of thread (or to
use such a bobbin after removing the thread wound on it by hand
until it becomes empty) in order to totally prevent the aforemen-
tioned problem. If it is necessary to use the bobbin which has been
used halfway, it is necessary to set the number of stitches to a
smaller value. The quantity of thread to be removed from a bobbin
is large initially, but it will become more and more adequate if the
"auto" is selected.
