Does the Cellink Neo App Beep setting only work if you have the unit hooked to your car or something. I just received mine and it has a charge. I flip the switch to low and it beeps as it powers up. I connect to it with my App and turn off the beep. I turn off the battery for a min and turn it back on and it still beeps. Tried this on high as well. Anyone else having issues turning off the beep? Is there a firmware I need for the battery? Thanks
