Connection to LCPU
LCPU may diagnose (check file system, recovering process, etc.) the SD memory card when turning on the power or

Therefore, it takes time until the SD memory card becomes available. When the GOT starts before the SD card
becomes available, a system alarm occurs. Adjust the opening screen time in the GOT setup so that no system alarm
occurs.
