When parameter setting of the dip switches, other than dip switch-A
No.3 (BUZZER), is performed, the LCD controller counts down 10
seconds, the same as at the power on state, right after the
completion of the parameter setting.
If any warning or alarm occurs during the parameter setting, the
setting session will be stopped automatically and the display will be
changed to the warning & alarm display screen.
