5.0 MODES OF OPERATION

The AI-2 has four modes of operation, Normal, Set/Hold, Command
and Setup. These modes are described in detail in this section.
The AI-2 will usually be used in Normal mode. Set/Hold mode is
used to modify and transfer times between registers. Command
mode is used for data read and save operations and Setup mode is
used to configure or modify the AI-2 operating parameters. In
Setup mode the front panel keys have different functions as
indicated by the gray italic legends. In all four modes the eight
system LEDs always show AI-2 status.

5.1 NORMAL MODE

Normal mode is the basic operational mode for the AI-2. The LCD
display will show one of six time code registers. These registers
can be selected by pressing the DISPLAY key. Each press of the
display key steps to the next time code register, when the last
register in the list is reached the display rotates back to the top.
The Cue Start Time and Tape Start Time registers are omitted from
the display rotation when the Cue menu option Use Times is set to
Off. The displays are as follows:
