3. Fraction of Oxygen (FO
2
)—The IQ-600 will display its current
FO
2
setting in one of three ways:
FO
2
NOT SET—If your IQ-600’s FO
2
setting has defaulted,
a series of horizontal bars appears. Again, see page 00 for
a more extensive discussion of why, when and how your
IQ-600’s FO
2
setting defaults.
FO
2
SET TO AIR—If you have set your IQ-600’s FO
2
to a
value of 21percent, the word Air will appear and the
percent sign, FO
2
and Nitrox notations will not appear.
FO
2
SET TO EAN22–EAN50—The FO
2
percentage appears,
along with the percent sign, FO
2
and Nitrox notations.
4. Altitude Rank—Current Altitude Rank (just as in Surface Mode).
5. Mode Indicator—The Mode Indicator will point to PLAN.
In addition to this data, if your IQ-600 determines that there is
residual nitrogen present from previous dives, it will also dis-
play Surface Interval Time and its Residual Nitrogen Bar Graph
during Dive Plan Mode—just as it does during Surface Mode.
Similarly, if the IQ-600 determines that the cumulative effect of
exposure to elevated PO
2
s from prior dives is significant, the
Oxygen Limit Index (OLI) will appear while in Dive Plan
Mode.
