If you remain well within normal recreational diving depth and
time limits, the odds that the cumulative effects of your exposure to
elevated partial pressures of oxygen will actually exceed the IQ-
600’s Oxygen Limit Index are almost nonexistent.
Out-of-Range Warning—There is one more warning that your
IQ-600 is theoretically capable of sounding and displaying. This
is the Out-of-Range Warning. This appears in Figure 14.
Figure 14: Out-of-Range Warning.
The Out-of-Range Warning consists of:
The computer’s audible alarm sounding for ten seconds.
Horizontal bars appearing in place of current and maximum
depth information.
The entire display screen blinking.
To activate the Out-of-Range Warning, you would have to do one
or more of the following:
Descend below 328 ft/100m.
Exceed an Actual Bottom Time (ABT) of 599 minutes.
Accrue a decompression obligation requiring stops deeper
than 49 ft/15m.
