What you need to pay attention when doing NEC Programming with AK500 PRO?
Some customers reflected to us that they can not write NEC chips with AK500 PRO. Now we will tell you the reason. When you write NEC chip with AK500 PRO, you need to use NEC Pro software. NEC PRO software is a kind of crack software, when you use it, you should close the anti-virus software on your computer first, or it will cancel the NEC PRO software as virus. So it certainly can not do the NEC function.
