If you have problems where your MC50 doesn't scan the correct barcode all the time and you have to delete the entry and rescan it, the "Imager Pick List" option will help!
The "Imager Pick List" will give a user the ability to choose which barcode they need scanned. This usually happens when multiple barcodes are beside each other.
The MC70, MC9090-G, and some newer MC50s have this option already, no need to upgrade the OS.
On the MC50 you will need to either update the OS or update the device to have the "Imager Pick List" option. Instructions for how to do the updates are in the link.
