Your GLX firmware may require an update/patch that will allow you to use your Power Amplifier regardless of the unsuccessful calibration:
- First make certain that your computer is using the most recent
release of DataStudio, which can be downloaded for free from here.
- Open DataStudio and connect your GLX. (The GLX should be powered-on.)
- When prompted to update the GLX firmware, click YES.
After installing the patch and updating your GLX firmware you may continue to receive a "Calibration Failed" message. To permanently stop receiving this message, you should contact Teacher Support to return the unit for modification. You may temporarily bypass the calibration sequence by pressing the F2 button on the GLX.
