  • Page 9: About This Manual

    About the 820 Scanner The MS-820 scanner can decode high density bar code symbols from 3 to 30 inches. Its IP65 and heavy industrial rating makes it ideal for applications such as conveyors, assembly lines, or embedding within machinery. Its application code resides in an onboard flash memory chip that can be easily updated by downloads.
