How to I reset the DFR22 back to the factory supplied settings?
NOTE: This procedure will clear all the presets programmed by the user. It is recommended to save the presets onto a computer before initiating the hard reset.
To perform a hard reset:
1. Power off the DFR22.
2. Hold down the following front panel buttons in "Row A": [Press to Lock/Hold to Clear] and [Bypass DFR Filters] - then power up the DFR22.
3. The preset indicator will count down as the reset takes place.
4. Release the buttons once countdown begins.
