Q
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 group calls and statuses.
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.
If you start to make a
red key call
or an emergency call to an emergency
number programmed into your radio when transmission barring is active, the
radio automatically deactivates transmission barring and attempts to make
the call. See Red key calls and emergency calls in direct mode on page 58.
Note:
If you start to make a
red key call
or an emergency call when
transmission barring is active, transmission barring will be deactivated, and
you should consider exiting the area where you wanted transmission to be
barred.
