Upgrading the Operating System on your CN3 Computer
You can use the Intermec Recovery Tools CD to reinstall or upgrade the oper-
ating system software on the CN3 Computer. For more information, con-
tact your Intermec representative for more information about this CD.
You can use the SmartSystems™ Foundation application from Intermec to
perform upgrades on your CN3 Computer, versions 2.0 or later. Contact
your Intermec representative for more information about the SmartSystems
Foundation software.
When you upgrade the operating system, you erase the current configura-
tion and replace it with the new default configuration. You will need to
reset the network parameters on the CN3 Computer to reestablish commu-
nications with other devices in the network. In other words, if you upgrade
the operating system and the default registry from the operating system has
changed, the registry is rolled back to the new default.
