RC-50: Preset Protect
Preset Protect is a feature in the RC-50 that protects the preset (factory) patches from being erased or edited. If you'd like to edit or erase any of the Preset Patches, you must first set Preset Protect to "OFF." Use the following steps to do so:
1. Press the SYSTEM/USB button.
2. Press PARAMETER right ( > ) until "SyS:PresetProtct" shows in the display.
3. Turn the PATCH/VALUE dial to select "OFF."
4. When you're finished, press EXIT to return to the Patch menu. The setting is saved automatically.
