• When material edge sensor
1
is pressed, ON/OFF of the
material edge sensor is changed over.
• When the material edge sensor, which is optionally available,
is connected to the operation panel, the ON/OFF switch of the
material edge sensor becomes effective.
• If the material edge sensor is specied, the sewing machine will
automatically stop running or perform thread trimming when the
sensor detects the material edge.
If the material edge sensor is used in combination
with the operation panel, carefully read the Instruc-
tion Manual for the material edge sensor beforehand.
• When automatic thread trimming switch
1
is pressed, ON/OFF
of the automatic thread trimming is changed over.
• This switch is rendered effective, when the material end
sensor is turned ON for the reverse feed stitching pattern, to
automatically activate the thread trimmer upon detection of the
material end.
(if the automatic reverse stitching (for end) is specified, the
thread trimmer will actuate after the sewing machine completes
the automatic reverse stitching (for end).)
• When one-shot automatic stitching switch
1
is pressed, ON/
OFF of the one-shot automatic stitching is changed over.
• This switch is used, in the constant-dimension stitching mode,
rectangular stitching mode, or in the process where the
material edge sensor is specied, to make the sewing machine
automatically perform sewing at the specified speed until
the end of the process is reached only by driving the sewing
machine once.
• When thread trimming prohibition switch
1
is pressed, ON/OFF
of the thread trimming prohibition is changed over.
• This switch is used to temporarily make the thread trimming
function inoperative.
The other performance of sewing machine is not affected by this
switch.
(If the automatic reverse stitching (for end) is specied, the sewing
machine will perform the automatic reverse stitching at the end of
sewing.)
• If the automatic thread trimming switch and the thread
trimming prohibition switch are both specified, the machine
will not perform thread trimming but stop with its needle up.
