Sdcampbell, that's great information. I used the Musical Surroundings test tones to calibrate my Fozgometer and it went smoothly and the Foz works well for azimuth adjustment. But if the unit ever seems to be "out of whack" and the test tone recalibration method doesn't work I'll know to just send it in for service. It's nice to know that the unit is so easily restored.
Regards,
Tom
