The MC75A is equipped with a memory backup battery which automatically charges from the fully-charged
main battery. When using the MC75A for the first time, the backup battery requires approximately 36 hours to
fully charge. This is also true any time the backup battery is discharged, which occurs when the main battery is
removed for several hours. The backup battery retains RAM data in memory for at least 15 minutes (at room
temperature) when the MC75A's main battery is removed. When the MC75A reaches a very low battery state,
the combination of main battery and backup battery retains RAM data in memory for at least 48 hours.
