5. TMO Service
The trunked mode operation (TMO) supports either half-duplex or full-duplex operation and allows the
terminals to communicate with each other via the TETRA network infrastructure. Thus features that
require network access are available. To operate in TMO mode, the terminal must be authorized by your
service provider, and must register with the network and stay within the network coverage.
