Metric:
This legend indicates that the dive computer is set to calculate and display altitude,
depth, and tank pressure values in the METRIC mode. Altitude and Depth will be
calculated in meters. Tank pressure will be calculated and displayed in either BAR or
Kg/cm2. You may select the metric display via the optional Analyst Personal Com-
puter Interface.
Mission OTU Clock:
This is a running clock that tracks your long-term risk to Oxygen Toxicity. This clock
may run for several weeks. The Mission OTU Clock is reset to 0:00 when the OTU
level is also 0.
Remain Time Air:
Predive Prediction Mode: When tank pressure greater than 500 psi is present on the
computer's high pressure transducer, the lesser of either remaining airtime
or the predicted no-decompression time is displayed for each depth.
Subsurface Mode: The display on which this data appears is dependent on whether
the remaining airtime is greater or less than the remaining no-decompres-
sion. If the remaining airtime is less than the remaining no-decompression
time, it will appear on the Main Display along with the AIR legend. If the
remaining airtime is greater than the remaining no-decompression time, it
will appear on the Alternate Display along with the AIR legend.
Emergency Decompression Mode: The remaining airtime is always displayed on the
Alternate Display.
Logbook Mode: If during the profile being displayed, the minimum recorded remain-
ing time data was remaining airtime, the Alternate Display will display this
data under the REMAIN TIME legend.
Remain Time NDC:
Predive Prediction Mode: When tank pressure greater than 500 psi is present on the
computer's high pressure transducer, the lesser of either remaining airtime
or the predicted no-decompression time is displayed for each depth. If there
is less than 500 psi present on the computer's high pressure transducer, all
predive predictions will be made using only no-decompression times.
NOTE: If the no-decompression limit for a given depth is less than two minutes,
your dive computer will not make a predive prediction for that depth.
Logbook Mode: If during the profile being displayed, the minimum recorded remain-
ing time data was remaining no-decompression time, the Alternate Display
will display this data under the REMAIN TIME legend.
Subsurface Mode: This is the amount of no-decompression time remaining dis-
played in hours and minutes.
CNS/OTU Toxicity Display: The number 2:00 under the REMAIN TIME legend is used
to indicate the CNS/OTU Toxicity Display.
O2 Mix Display: The number 1:00 under the REMAIN TIME legend is used to indicate
the O2 Mix Display.
Battery/Altitude Display: The number 0:00 under the REMAIN TIME legend is used to
indicate the Battery/Altitude Display.
