OD-20: How do I restore the memory settings to their factory defaults?

The following procedure restores the memories 1–4, Pedal Mode setting, and MEMORY Number Indication setting on the OD-20 to their factory defaults.

NOTE: This operation completely clears all settings currently stored in memories 1–4.

1. Turn off the power.
   1. When running on battery power: Disconnect the connection plug from the INPUT jack.
   2. When running on power from an AC adaptor: Disconnect the plug from the AC ADAPTOR jack.
2. While holding down the WRITE button, switch on the power.

3. Release the WRITE button.
   The MEMORY Number indicators blink.

   To cancel the operation, operate the EFFECT ON/OFF pedal or the MANUAL/MEMORY pedal before pressing the MEMORY WRITE button. The OD-20 returns to its ordinary state.

4. Press the MEMORY WRITE button.
   After the MEMORY Number indicators begin blinking rapidly, the settings are stored in memory, and the OD-20 returns to its ordinary state.
