The ATMOS 2 will also enter an
Immediate Violation Mode
5
minutes after reaching the Surface from a dive in which a Delayed
Violation occurred. On the surface,
Gauge Mode
displays the
Dive Number, Surface Interval, Temperature, and Time of Day
with the full Nitrogen and O2 Bar Graphs flashing (Fig. 57). It
does not provide the FO2, Dive Planner, or Time to Fly and
Desaturate features. The countdown timer that appears when you
try to access Time to Fly does not represent 'Time to Fly'. It is the
time remaining before the ATMOS 2 can resume operation with
full features and functions.
This condition previously described is considered a Permanent
Violation, and in the event that a dive is made during the 24
hour period, a full 24 hour surface interval must then be
served before all functions are restored.
HIGH PO2 DIVE MODE
As depth increases during a dive, the partial pressure of oxygen
(PO2) increases. When PO2 becomes equal to, or greater than,
1.40 ATA, or 0.2 ATA less than the PO2 Alarm set point (a
user setting);
the Audible Alarm will sound (unless set OFF), and
the current PO2 value, PO2 symbol, O2 segment of the O2 Bar
Graph, and UP Arrow will appear on the Main Display as a warn-
ing until PO2 decreases. Current Depth and Dive Time Remaining
will also be displayed (Fig. 58).
