If you'd like to redo the ES-5's settings from scratch, you can use the following procedure to clear the internal memory and reload its factory settings:
1. Press the EDIT button.
2. Press the Left/Right Arrow buttons until you get to the
Utility category.
3. Press ENTER.
4. Press the Page Right button until you get to the Factory Reset screen.
5. Press ENTER.
6. Using the Page Left/Right and -/+ buttons, you can set the range of data you wish
to Reset.
This data that gets reset can range from a complete reset that includes:
From: System (All System Settings) To: Patch 855 (200 Patches).
Or, you can use the -/+ buttons to edit the range of data that gets reset,
leaving out System settings, in order to keep them intact, or including System
Settings and restricting the range of Patches that get reset to a lower number
than the highest Patch.
