9-17. Clearing all memory settings
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.
While pressing the R/W switch (1), turn on the power. This will clear all of the memory setting.

This operation causes memory switch settings to be returned to their initial settings, and also clears all contents of the
memory such as user programs.
