KO Propo EX-1 Mars..."Back Up Error"?????
Today my KO Propo Mars suddenly gave a few weird beeps, lost control of my vehicle, and now has "Back Up Error" stuck on the LCD screen. None of the buttons work to adjust anything, only the 2 quick trims on the wheel, but I still have control of my vehicle.
What does that mean? I have searched in the manual and cannot find anything about this. Has the backup battery inside finally packed it in? If so, do I HAVE to send it back to KO for them to replace it?
Any comments or thoughts would be greatly appreciated.
Thank you very much.
