Chapter 1 Using the 9400CE Mobile Computer
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!

Tap and hold the DiskOnChip icon to select Properties from the pop-up menu. In the Properties tab
(right below), it displays the current capacity and usage of DiskOnChip.
