Strange thing happened last week at the races.. The radio was switched off, I put my radio down (stood up), the table was knocked, tipping the radio. I stopped the radio from falling over (it wasn't even close to hitting the surface), and it just turned itself on! The display was on, lights were on, I could navigate the menu, all while the switch was off.

I have the Spektrum Pro module, and it will only activate when the switch if on. The receivers go into safe mode when the switch is off.

I now have to pull the pack out when I put it away.

Is there a common fix for this?
