battery capacity for memory backup. Once the battery is drained, the system
RAM memory is lost and the unit must reboot.
In most real-time transaction environments, this is not a problem (it only
takes a few seconds to boot). However, batch transaction environments,
where data is not saved to non-volatile memory (a microSD FLASH card),
may need to pay particular attention to this parameter. Psion Teklogix does
not recommend the storage of any valuable data in system RAM.

RAM (such as the registry or file system).
If the user's application does not save data to RAM, Psion Teklogix recom-
mends keeping the Suspend Threshold setting as low as possible to
maximize battery run time.
