Question:
How do I adjust the contrast on the dbx ZonePro 640/1260/640m/1260m when I cannot view the screen
Answer:
Press the Utility button (this is the Data Wheel Encoder that doubles as a button) and rotate. By default this will change the contrast setting. Adjust the Data Wheel Encoder to the right or left until the characters are visible again.
