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.
