The signal will continue until the condition is corrected. The control panels for the engines are equipped with an audio alarm for the low oil pressure and an audio alarm for the high coolant temperature. The control panels for the engines are also equipped with a warning lamp for the low oil pressure and a warning lamp for the high coolant temperature. Refer to Operation and Maintenance Manual, "Control Panel" for the locations and types of warning lamps.
