When problems occur while the unit is operating, the self-diagnosis func-
tion starts working, and displays on the LCD screen what to do.
Details of the self-diagnosis functions are provided in the Instruction 
manual.

When problems occur while the unit is operating, the LCD screen shows 
a 4-digit display consisting of an alphabet and numbers, which blinks at 
3.2 Hz. This 5-character display indicates the “repaired by:”, “block” in 
which the problem occurred, and “detailed code” of the problem.
