Does anyone know where I can find a Portuguese version of the manual for the Triopo TR 586 EX speedlight?
I found a manual in (Brazilian?) Portuguese for the Triopo TR-980. Perhaps it has some guidance that you can apply to your TR-586EX model.
Desculpe. Given that the only "documentation" I can find on this model of flash is a Chinese video I can't even load, I'd say your chances of finding an online PDF of the manual in Portuguese are zero. I couldn't even find an English-language PDF you could run through Google translation.
