If you mean, it doesn't transmit, I suppose I wasn't clear. Some radios only give you 8 repeater channels that will transmit. The rest of them can listen but not transmit. I think they do this because they do not understand the regulations for GMRS radios.
If you mean, it doesn't receive, you need to send the radio back and ask for a new one that works or get your money back. It should at least receive on those other channels.
