I recently purchased 3 hytera RD982S (uhf 400-470) spit repeaters from a SK estate.The problem I am having is when I try to program them both the PC37 and 47 cables upon power up I hear the usb tone and after approx 10 secs it diconnects the usb and won't read the repeater.Acts like it is dealer locked out as none of the front keys work and the displays don't light up.All 3 do exactly the same thing.The back plate show V6.1.03.003.I don't know if it has been updated as I can't read it.Any help or suggestions greatly appreciated.
The repeaters go through there startup and digital light is flashing blue at the end of startup sequence
