The Warnings & Cautions discussed in this manual cant cover all possible conditions/situations. It must be understood that common sense and caution are factors which cant be built into this product.
I can't remember, but I thought one of the latest.
I will try to connect to the PC and find out the firmware version. It's kinda strange because I had no problem at all with V3. Well I have to say the V3 had a older firmware version. Because newer versions didn't work with mine DS2X and 6S Hyperion lipo.
