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 buyers 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 manufacturers 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.

Example Description
while Courier font (bold) indicates a program, a fragment of a
program, or a Dynamic C keyword or phrase.
// IN-01… Program comments are written in Courier font, plain face.
Italics Indicates that something should be typed instead of the
italicized words (e.g., in place of filename, type a file’s
name).
Edit Sans serif font (bold) signifies a menu or menu selection.
. . . An ellipsis indicates that (1) irrelevant program text is
omitted for brevity or that (2) preceding program text may
be repeated indefinitely.
