Notice to Users

Z-WORLD PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL

COMPONENTS IN LIFE-SUPPORT DEVICES OR SYSTEMS UNLESS A SPE-

CIFIC WRITTEN AGREEMENT REGARDING SUCH INTENDED USE IS EN-

TERED INTO BETWEEN THE CUSTOMER AND Z-WORLD PRIOR TO USE.

Life-support devices or systems are devices or systems intended for surgical im-

plantation into the body or to sustain life, and whose failure to perform, when

properly used in accordance with instructions for use provided in the labeling and

users manual, can be reasonably expected to result in significant injury.

No complex software or hardware system is perfect. Bugs are always present in a

system of any size. In order to prevent danger to life or property, it is the responsi-

bility of the system designer to incorporate redundant protective mechanisms ap-

propriate to the risk involved.

All Z-World products are 100 percent functionally tested. Additional testing may

include visual quality control inspections or mechanical defects analyzer inspections.

Specifications are based on characterization of tested sample units rather than testing

over temperature and voltage of each unit. Z-World may qualify components to operate

within a range of parameters that is different from the manufacturers recommended

range. This strategy is believed to be more economical and effective. Additional

testing or burn-in of an individual unit is available by special arrangement.
