Don't Panic, your KUDUwave is most likely not out of calibration.
If the X-check test fails, a message will display the most common causes of test failure. These can be something as simple as bumping or moving the KUDUwave while the X-check is running or blockage in the sound tube.
Troubleshoot by going through this checklist and then clicking the “Retest” button for the side that failed.
For more technical information on a failed test view the X-check report. Failed frequencies are shown in red along with a reason of why the test failed.
If the test still fails after you have followed the instructions then your KUDUwave™ could be out of calibration. Contact us to make a calibration booking.
