• Mode 1
Enter this mode when turns the power on while pressing the AUTO button of each player simultaneously.
Mode 1 can confirm the state of each other button with FL other than the operation of mode 2.

Enter this mode when connects a screw terminal to GND and +8V from the external DC power supply to V+8B by
controller section being simple. Further, it is not necessary to press buttons in the power-up.
Note : Mode 1 and mode 2 are the same operations basically. But a power supply of FL system is not supplied in case of mode 2.
Therefore cannot confirm it with FL.
