The touch screens on PerfectWave products can get off registration or may not have been set exactly right from the factory. Â In this case, it is possible to recalibrate the touch screen through a simple process.
Turn the DAC off from the master switch in the back panel. Let the unit discharge for 10-20 seconds. Then turn the unit on while holding down the PS Audio blue button on the top left corner of the front panel. This should bring the unit to a screen calibration.
You will have to touch each of the four corners in numerical sequence.  Use a small object like the eraser on a pencil for best results.  Do not use anything sharp on the touch screen.
Once the calibration process is finished the unit will restart.

We’ll need your unit’s serial number to get you the best service options.
Best,
Hi, I’ve just unsuccessfully tried to recalibrate the screen. Unless I didn’t understand the exact signification of “numerical sequence” that I guess is touching each corner starting with the upper left, then upper right then down right and down left ?
Yes the unit will restart but with my inverted DSD screen it took about 15 of these recalibration restarts before the screen righted itself. That’s way too much to go through IMO.
When I followed these instructions, the first screen said something like “set defaults?”. So I pressed the little button on top left of screen to confirm and everything booted up with display working again. Is this a new solution/sequence with the latest software?
