How to calibrate a PerfectWave Touch Screen

Written by Paul McGowan

The touch screens on PerfectWave products can get off registration or may not have been set exactly right from the factory. 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.
