DANGER
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall
outlet before opening the face plate of the control box. Touching areas where high voltages are present
can result in severe injury.
If a malfunction should occur with the sewing machine, a buzzer will sound and an error code will appear in the
display window. Follow the remedy procedure to eliminate the cause of the problem.
⋅
For errors which do not require the power to be turned off (i.e. errors which can be reset), two short beeps will
sound. For error E-02, three short beeps will sound.
⋅
For errors which require the power to be turned off (i.e. errors which cannot be reset), a single long beep will
sound.
