Notice to Users

When a system failure may cause serious consequences, protecting life and

property against such consequences with a backup system or safety device

is essential. The buyer agrees that protection against consequences

resulting from system failure is the buyers responsibility.

This device is not approved for life-support or medical systems.

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.
