If the sewing machine stops operating normally, the cause may be that an incorrect memory setting may have been made by means of the memory switch, for instance. In such cases, carry out the following procedure to clear the memory, and also check the DIP switch settings.

[ Method ]

While pressing the RESET switch, turn on the power. This will clear all of the memory setting.

NOTE:

This operation causes all settings stored in memory such as memory switch and user program settings to be cleared.
