Communication Error Warning If a communication error is generated between e-EPOS controller and instrument panel, this symbol will be displayed. When this symbol is displayed, contact a DOOSAN distributor or sales agency. NOTE: If a communication error occurs during operation, the last mode setting is stored. e.g. power mode, work mode and auto idle are stored during failure. NOTE: When starter switch is turned to the "I" (ON) position during a state of communication error failure, the e-EPOS controller will default to the following modes.
