Here’s how to return the SH-4d to its factory-set state.

  1. On the MENU screen, select “FACTORY RESET”, and then press the [ENTER] button to display the dialog screen.

  2. Press the [æ] button and select “OK”, and then press the [ENTER] button to execute the factory reset.

    Never turn off the power while the “Executing...” message is shown and the unit is still processing.

  3. Once the message “Completed. Turn the power off.” appears on the screen, turn this unit off.
