The radio has been “Killed” It either needs to be sent the unkill code via DTMF, or it needs reset via the programming software.

Load up Chirp and send the radio the programming file used to program it with last. This will open it up. While in chirp, go ahead and disable the dtmf kill function, so this won’t happen again.
