@@m0tef901 just watched a Russian reviewer and although I couldn’t understand him, it looks like he might have done it by pressing the PTT while turning on the radio. Can you try this and report your findings please.
@@jamesfairhurst8525 I did try it quick this morning and I didn’t manage to find the right combination of keys. I will keep experimenting and report back if I have any luck with it.
Don't recommend buying directly from Retevis, they won't exchange or repair a bad radio I bought directly from them. Buy from someone that has good return warranty.
