Each key has its own key code. The key codes are assigned incrementally from left to right on the key
board. (Refer to the keyboard in the schematic diagrams.)
In the auto mode, the key input sequence is limited so that the keys must be pressed in the order of the
key code as mentioned above. If a key is pressed in the wrong order, the SF-5300B beeps.
