Ok, I have observed that when I power the ASIAIR and the Camera using a direct cable from my power bank (instead of the patch from the AM5) the beep is gone, at least if the mount doesn't move much. However, even with almost full battery in the power bank, if I move the mount to look for a location or using the GoTo function, it beeps sometimes, (not continuously)... I guess, the 2 motors moving at the same time is quite energy consuming and the voltage drops a bit...
