The reason is probably that you had no BT connection when you did this settings so they were not transfered to Alkatronic. When doing settings always be sure that the green dot is ligtning, and that you get thet settings confirmed in the LCD of the Alkatronic. If that is confirmed, the settings will definitely be saved.
If using iOS this is always very stable connection, if using Android, some units have BT issues, and thats on the android side, so if you use android take extra care that you see the settings confirmed in LCD of the unit. Very soon (already working, I am testing it) you can do these settings also from the cloud!, then you do not have to have BT connection at all, but just go to the cloud page (our www address, see manual), and do the settings from there, and those will be transferred to the machine within 10-30 seconds wherever you are in the word!:-) /Jonas, Designer
