This radio works only in trunked radio networks, since there is no network available at your place, it fails to attach with the network.

I think, you don't know where this radio was used, so I don't think you want to hook up to the trunked network.

If you want to use the radio without a tetra network, you can use it in DMO mode.

Without specific programming, there is no use for the radio in any tetra network, except for the initially one.
