Emergency Decompression Mode
WARNING: Your NEMESIS™ IIa NITROX should not be used for deliberate decom-
pression diving, but merely as an aid to assist you during ascent should you mis-
takenly overstay your no-decompression limit. Cochran Undersea Technology in
no way encourages deliberate decompression diving.
Should you exceed your NDC time limit, your NEMESIS™ IIa NITROX will enter its
Emergency Decompression Mode. Five audible warning chirps will sound and the
DEC legend will appear on your WU. Decompression ceilings up to 90 feet are
calculated. An additional five chirp audible warning will sound if a decompression
ceiling greater than 60 feet is calculated.
WARNING: You should IMMEDIATELY begin your ascent to the proper CEILing depth
upon hearing these warnings.
Your NEMESIS™ IIa NITROX is configured at the factory to alternate between total
decompression time for three seconds and time at current stop for three seconds. Via
the optional Analyst, you can select to have only total decompression time or stop time
displayed if you so desire.
CEILING is the depth to which you must ascend, BUT NOT EXCEED, for your first
emergency decompression stop. The WU display will indicate the various ceiling
stop depths as follows:
Ceiling Calculated Ceiling Displayed
10 foot 10
20 foot 20
30 foot 30
40 foot 40
50 foot 50
60 foot 60
70 foot 7
80 foot 8
90 foot 9
NOTE: When completing your decompression stops, minor changes in your depth
may occur due to swells at the surface. For this reason, you should make your stop
slightly deeper than the CEILing depth. Your NEMESIS™ IIa NITROX will continue to
give decompression credit when this precaution is taken.
Time spent above a CEILing depth will not be credited to the required decompression
obligation. Instead, a 1.5 second penalty will be added to that time for each one
second spent above the CEILing.
CAUTION: Ascending above the CEILing depth will cause your NEMESIS™ IIa NITROX
to issue a warning chirp. The current depth digits and the WARNING legend will
flash. Both the audible alarm and the flashing display will continue until you de-
scend below the CEILing depth.
Your BOTTOM time, TANK pressure, ASCENT rate, and DEPTH gauge will continue to
operate normally as if you were in the Subsurface Mode.
