Network Selection - Nokia THR880 User Manual

When transmission barring is active, in 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,
for example, 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 will automatically deactivate transmission barring and
attempt to make the call. If the radio is in direct mode, the radio will
attempt to switch to network mode, deactivate transmission barring
and attempt to make the call.
Warning: If you start to make a red key call or an emergency
call, transmission barring will be deactivated and you should
consider exiting the area where you wanted transmission to be
barred.
See Transmission barring on page 73 for how to activate or deactivate
transmission barring. Note that transmission barring should be active
before you enter the area where you want transmission to be barred. The
indicator or is displayed in standby mode when transmission
barring is active. Depending on predefined radio settings, the radio may
send a notification message to the network about the activation. The
indicator is displayed if the message does not need to be sent or
message sending failed, and the indicator
message has been sent.

Network selection

Next to your predefined home network, you may be able to select other
networks in which your radio can operate (network service), for
example, if you are not in the coverage area of your home network. The
network can be changed automatically or manually, see Network
selection on page 76.
