1.3.3 Memory & Calendar
The terminal is equipped with two card slots, one SD and one CompactFlash Type II. You
may upgrade memory by inserting an optional SD or CF memory card.
Warning: If not factory-installed, the Ingress Protection rating of enclosures may not
be the same as claimed.
Read-only Memory (ROM)
 A total of 128 megabytes flash memory.
 Mostly, it is for storing OS (Windows Mobile 2003) and custom application programs.
 Yet a small portion of the memory is referred to as DiskOnChip, which can store data and
programs that you wish to retain even after a hard reset.
Random-access Memory (RAM)
 A total of 64 megabytes SDRAM.
 It is used for storing and running programs, as well as storing program data.
 Its contents will be retained by the backup battery.
Calendar
 Equipped with a calendar chip for accurate time/date logging.
 Non-stop operation is provided through the backup battery.
Caution of Data Loss
When the main battery is removed or drained, the backup battery is to retain the
contents of SDRAM and maintain the OS in suspend mode for at least thirty
minutes, on condition that the backup battery has already been fully charged.
If the terminal is to be put away for a couple of days, you should be aware that data
loss occurs when both the main and backup batteries discharge completely.
Therefore, it is necessary to backup data and files before putting away the terminal.
