My satin V2 ProVari started to get the E4 error. I have cleaned it and changed the battery and atty.. (it both works on my other ProVaris) Nothing helps.
If I slapp it in the bottom I can take 1 to 3 drags without E4 and then it's back. I can acces the meny and set the voltage but nothing helps.
Anyone with an idea what to do?
