Transmission barring
When transmission barring is active, the radio does not send any signals to the
network, and only limited network services are available. In the network mode, the
radio can only receive group calls and status and text messages addressed to talk
groups, providing that the radio is registered to the network. In the direct mode,
the radio can receive direct mode calls. When transmission barring is active, the
radio cannot re-register to the network, for example, if it is switched off and then
on again.
The limited network services in the network mode are only available in the
coverage area of the network cell where the radio was last registered. The radio
cannot register to other network cells while transmission barring is active, and
therefore the area of operation may be limited.
When transmission barring is active in the network mode, the radio cannot send
the necessary information to the network about changes in talk groups. When
transmission barring is active, you cannot change the selected group. If you make
any other changes that affect talk groups, such as change the selected folder,
home group, or the scanning priority of a group, you will not be able to receive
further communication from the affected groups. After transmission barring has
been deactivated, the radio can attempt to negotiate the changes with the
network.
