With its power on delay feature, AIV-HM76V1FL protects against sudden shutdown caused by sudden voltage surge or drop. Software-off delay ensures power subsystem automatically dismisses OFF procedure and goes back to operating condition if ignition or remote switch is turned on again. While shutdown delay lets system complete data-rewriting prior to each shut down, hard-off delay reduces energy loss when power subsystem detects OS shut down and standby power is turned off.
