NOTICE TO USERS

RABBIT AND Z-WORLD PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPO- NENTS IN LIFE-SUPPORT DEVICES OR SYSTEMS UNLESS A SPECIFIC WRITTEN AGREEMENT SIGNED BY A CORPORATE OFFICER OF DIGI INTERNATIONAL IS ENTERED INTO BETWEEN THE CUSTOMER AND DIGI INTERNATIONAL.

No complex software or hardware system is perfect. Bugs are always present in a system of any size, and microprocessor systems are subject to failure due to aging, defects, electrical upsets, and various other causes. In order to prevent danger to life or property, it is the responsibility of the system designers, who are our customers, to incorporate redundant protective mechanisms appropriate to the risk involved. Even with the best practices, human error and improbable coincidences can still conspire to result in damaging or dan- gerous system failures. Our products cannot be made perfect or near-perfect without causing them to cost so much as to preclude any practical use, thus our products reflect our “reasonable commercial efforts.”

All Rabbit and Z-World products are functionally tested. Although our tests are comprehensive and carefully constructed, 100% test coverage of every possible defect is not practical. Our products are specified for operation under certain environmental and electrical conditions. Our specifications are based on analysis and sample testing. Individual units are not usually tested under all environmental and electrical conditions. Indi- vidual components may be specified for different environmental or electrical conditions than our assembly containing the components. In this case we have qualified the components through analysis and testing to operate successfully in the particular circumstances in which they are used.
