Operation beep (for models equipped with the operation beep)

Each time a key is pressed you will hear one beep. If a non-functioning key is pressed or an incorrect operation is performed you will hear two or four beeps (only for models equipped with the operation beep).

■If a key is pressed (correct operation) One beep sounds.

■If an incorrect operation is performed or a non-functioning key is pressed Two or four beeps sound.

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

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