Abnormity Diagnose

1. Sensor diagnose: 2 seconds after the sensors open circuit or short
circuit, the unit will turn off automatically and the LED will show E0 until
the sensors resume.
2. Keystroke circuit error diagnose: When power on for the first time, the
PCB will check the keystroke circuit, if the sampling value is different with
the theory value, the LED will show E1, which means failed keystroke
circuit. The keyboard is locked and so invalid, but the remote control is
working normally.
