displays the Dive Number, Tempera-
ture, Time of Day, Surface Interval, and Tank Pressure (Fig. 74).
It does not provide access to the FO2, PDPS, 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 only provided to inform
you of the time remaining before normal VT Pro operation can
resume with full features and functions.
This condition is 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
When partial pressure of oxygen (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 red LED warning will flash, 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 warning until PO2 de-
creases. Current Depth, Dive Time Remaining, and Tank Pressure
will also be displayed (Fig. 75).
