Modes of operation

Your radio has two modes of operation: network mode and direct mode.
In network mode, the radio operates via the TETRA network. In direct
mode, the radio operates without the network, so the radios are
communicating directly with each other. In direct mode only some of
the radio's functions are available. See Direct mode on page 49 for more
information about direct mode.

Shared memory

The following features in this radio may share memory: phone book,
calendar, and to-do notes. Using any such features may reduce the
memory available for any features sharing memory. This is especially
true with heavy use of any of the features (although some of the
features may have a certain amount of memory specially allotted to
them in addition to the amount of memory shared with other features).
For example, saving many names or notes may take all of the shared
memory and your radio may display a message that the memory is full.
In this case, delete some of the information or entries stored in the
shared memory features before continuing.

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
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 direct mode, the radio can receive direct mode calls.
Note that when transmission barring is active, the radio cannot re-
register to the network, for example, if it is switched off and then on
again.
Note: The limited network services in 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.
