Itwill run for 4 minutes (minimum), until the engine cool-ant temperature is above 50°C (122°F), and the bat-tery is fully charged (O.K. displays in the Data Listvoltage line, and charging amps are less than the Con-figured setting). While the unit is running in SleepMode, "SLEEP WARNING: NO TEMP CONTROL" willflash in the MessageCenter, and the Display (set pointand refrigerated box temperature) will be off.If the unit is already running when Sleep Mode is se-lected, it will continue to run until the conditions de-scribed above are met.While the unit is cycled off in Sleep Mode, "SLEEPMODE, OFF/ON TO WAKE" will be displayed in theMessageCenter.
