So i bought an OKK V1 Meldas 64 control (Mitsubishi) and well the battery died. Wasn't much of a worry because we bought a new one and were expecting to input new parameters as soon as it launched buuuttt... the screens black with just an orange tic in the top left and nothing happens and no buttons hold any control it just beeps at ever button with no function.. If anyone has any tips or suggestions would greatly appreciate the help!
