A "CODE NOT FREE" Error on a Sharp UP-700 is displayed when trying to log on a server that is allready logged on to another cash register in your system. It is also a possability that particular server number is locked up (if it is not allready signed on at a different terminal).
To Resolve this error you need to press Cancel or Clear, and try a different Server Number (code). If this does not resolve the problem, contact Inland Cash Register or your local Sharp Dealer.
