Hello Mr.Terry
i have 2 pcs of pz400 i recently bought with the programming cable .
I downloaded the software from the Unimo website and started programming the Radio.
There is an option called "Default Data" and I set my radio to default , but since then my radio shows Shell Mode and the manufacturer tuning date to 2001-03-15!
I've tried everything but no luck!
i've sent an email a few weeks ago but no response!
