1.2 MEMORY 
 Read-only Memory (ROM) 
128 megabytes flash memory for storing OS (Windows CE 5.0) 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 hardware reset. 
 Random-access Memory (RAM) 
64 or 128 megabytes SDRAM for storing and running programs, as well as storing 
program data. Its contents will be retained by the backup battery. 
 Expansion Slot 
The mobile computer is equipped with one miniSD card slot, which is user 
accessible. You may upgrade memory by inserting an optional miniSD memory 
card. 
1.2.1 CAUTION OF DATA LOSS 
When the main battery is removed or drained, the backup battery on the main 
board is to retain the contents of SRAM and maintain the OS in suspend mode for at 
least 20 hours, on condition that the backup battery has already been fully charged. 
If you want to put away the mobile computer 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 mobile computer!
