Notes:
*1 RAM: A form of data storage that can be accessed directly in any random order. Stored data is erased when the power is turned off. RAM
of Infilex AC is backed up by a lithium battery.
*2 RTC: A computer clock that keeps track of the current time. RTC of Infilex AC is backed up by a lithium battery.
