Saving and Recalling Presets
The preset buttons use a simple press/hold interface. To recall a preset, simply briefly press the appropriate button. A short success beep will confirm your request if a preset was saved. If no preset is saved, an “error” tone will play. To save a preset, simply press and hold the appropriate key until a confirmation tone plays.
Presets are non-volatile and are saved between power cycles and even if power is completely lost.
