I called last week and she helped me calibrate it as the instrutions are not that clear. I have been sick with the flu so I've not called back but will do so on tuesday to find out if you can turn music off. But I have a feeling you can't or the only way would be to turn the turner off and just do it twice a day by using the test mode. But I really do like it I bought mine off ebay from kemps koops. Then when it came it was shipped from Brinsea and their are not to far from me in titusville fl. So it would have been easier to get one from them she did say that if it didn't calibrate to call her back and they would fix it for me.
