LED indication at Service Calls

If service calls occur, all four LEDs blink on and off to notice it. And then when press the [Go]
button, distinguish a fault from the specific combination of ON/OFF and status color of the LEDs.
When entering this state, instruct the end user to turn off the power switch once, and wait a few
seconds. Then, turn on the power switch again. However, if the error is not cleared and the
service call is appeared, see the reference page to take the corrective action.
