Nothing appears in the LCD

If nothing appears in the LCD when the sewing 
machine is turned on, the brightness of the LCD is 
either too light or too dark. If this is the case, perform 
the following operation.

1

Turn off the sewing machine.

2

While pressing 

 (back key) in the 

operation panel, turn on the sewing machine.

 (–) or 

 (+).

Adjust the brightness of the LCD so that the 
screens can be seen.

4

again.

Operation beep

Each time a key is pressed or an incorrect operation 
is performed, a beep is sounded.

■

For a correct operation

One beep is sounded.

■

If an incorrect operation is performed

Two or four beeps are sounded.

■

If the machine locks up, for example, because 
the thread is tangled

The sewing machine continues to beep for four 
seconds. The machine automatically stops.
Be sure to check for the cause of the error, and 
correct it before continuing to sew.
