The speed adjustment can help you control sewing on:

For thicker materials such as denim or canvas, a lower operating speed can give you better control during stitching.

2. Remove the existing display panel according to the machine’s service procedure.
3. Disconnect the existing panel cable carefully.
4. Compare the old connector and cable with the replacement unit.
5. Insert the red multi-pin connector into the compatible control-box socket.
6. Secure the new panel in the original mounting position.
7. Switch on the sewing machine and check the LED display.
8. Test the + and – buttons before starting normal sewing.

Never force the connector into the socket. If the plug, wiring, or panel design differs from your existing unit, verify compatibility before installation.
