NO DECOMPRESSION LIMITS
Refer to the tables in the Operating Manual provided with your specific PDC for No De-
compression Limits for various altitudes. Note that the NDLs do not extend beyond the
limit to which the range of the specific PDC's Pre Dive Planning Sequence, a maximum of
either 160 FT (48 M), or 190 FT (57 M).
When the Conservative Factor feature is set On, the NDLs which are based on the algo-
rithm selected and used for Ni/O2 calculations and displays relating to Plan and DTR,
will be reduced to the values available at the altitude level that is 3,000 feet (915 meters)
higher. Refer to the NDL charts in the back of the Operating Manual.
OXYGEN EXPOSURE LIMITS
Predicted exposure limits and oxygen calculations associated with the PDCs' Nitrox modes
are based on maximum exposure durations published by the NOAA (National Oceanic
and Atmospheric Administration) in the NOAA Diving Manual.
DIVE TIME REMAINING* (DTR)
One of the most important features of Oceanic PDCs is the DTR numeric display. The
PDCs constantly monitor no decompression status and oxygen exposure. Integrated mod-
els also monitor the rate of air consumption.
The DTR display will indicate the time that is calculated to be more critical for you at that
particular moment (i.e.; whichever time is the least amount available). The specific time
being displayed is identified by an icon or graphic.
