Chapter 1 Using 8000 Mobile Computer

1.2 MEMORY

The collected data can be sent back to a host computer immediately over wireless
networks, or stored in memory (SRAM) and upload later. The mobile computer is
equipped with a calendar chip for accurate time/date logging. 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 running of real-time clock and calendar for at least 30 days, 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 upload data and files before putting away the mobile
computer!

2 megabytes flash memory for storing core, OS, application programs, font, etc.

1.2.2 RANDOM-ACCESS MEMORY (RAM)
