6-3 Operation Modes and the System Menu
The NT21 operates in four modes: the RUN, Transmit, Maintenance, and Ex-
pansion modes. These modes are selected from the System Menu.
In addition, the NT21 also features the System Installer mode, which is used
specifically for installing the system program.
The System Installer mode is selected by operation at the panel when the NT21
power is switched ON.
