The firmware programming with a PC is very similar to the JUMA TRX2 programming.

Follow the JUMA TRX2 programming istruction with the following exception



When the PC software is waiting the JUMA TX500/136 Flash Writer to be started,
start up JUMA TX500/TX136 while keeping OPER button pressed (instead of the VFO button in TRX2)

Otherwise follow the TRX2 instructions found here
