Hello, I have an NX-300 that an employee bought from an auction, it was from a business that closed down. He wants to use the radio at our business however when I try to read the radio the software is asking for a password. There is no way for us to figure out where the radio came from, so I can't really track down the dealer it came from. I mostly work with Motorola radios, so I am not too sure how to resolve this. Any advise would be appreciated. Thank you!
