Hello–I have owned the DAC for about three years now and been very happy with it. We recently had the fires in Santa Barbara and I moved the DAC out of the house for several days. When I re-installed the device the unit first required the display calibration which I did. The LCD display is now upside down. I have tried to recalibrate a few times and it always wakes up upside down. Any clues as to how to resolve this? I can try upgrading FW but wanted to check if I am missing something. Thanks ---

Hi BLKennedy, Thanks for reaching out to us about this and sorry to hear that you are having this trouble. Calibrating the display should solve the issue. Follow this tutorial for that: [http://www.psaudio.com/ps\_how/how-to-calibrate-a-perfectwave-touch-screen/](http://www.psaudio.com/ps_how/how-to-calibrate-a-perfectwave-touch-screen/) If the display continues to power up upside down try pressing the corner buttons in reverse order (4,3,2,1). If you continue to have trouble please reach out to us at [service@psaudio.com](mailto:service@psaudio.com) Thanks and kind wishes, - Jeremy ---

I re-calibrated multiple times and it finally flipped back. Thanks! ---

Very good. Now you can flip the DAC back over to right-side-up.
