The power on delay featured on the AIV-HM76V1FL protects the vehicle PC from sudden shutdown caused by sudden voltage surge or drop. The software-off delay is the delay time once the ignition is OFF until power subsystem sends a turn off command to the motherboard. During this time, if the ignition is turned ON again, the power subsystem will automatically dismiss the OFF procedure, going back to operating condition.
The shutdown delay allows the system to complete data-rewriting prior to each shut down. A higher value configuration is recommended if it takes longer time to shut down the program. The hard-off delay is the delay time after power subsystem detects the OS has been shut down until the standby power is turned off.
