There are three cases depending on the LCD Message index number:
•
Indexes 00h to 07h
correspond to messages that automatically display on the reader.
In most cases, the terminal does not trigger these messages.
•
Indexes 08h to 0Bh
are messages triggered by the terminal.
•
Index FFh
indicates that the command is only setting the buzzer and/or LEDs. The
terminal does not display a message.
After completing a successful transaction, the "Thank You" message remains on the LCD until
the terminal sends a new
