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 25 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!
