Memory Backup Battery
The following shows levels available for the memory backup battery.
The terminal’s system checks the status of the backup battery every five minutes. Since power
source of charging the memory backup battery is supplied by the battery pack, charging it may not
be carried out sufficiently if the battery pack has not been accommodated for a long period or is
not being fully charged. In other words, the memory backup battery will be normally charged if
the battery pack has a sufficient level of battery capacity. Prior to operating the terminal, be sure
that the memory backup battery is charged fully; otherwise the RAM content may not be held
when the battery pack is demounted.
