Operation Manual

60
Upon ascending above 330 feet (99.9 meters), the Current Depth display will be restored,
however Max Depth will only display 3 dashes for the remainder of that dive. The Log for
that dive will display 3 dashes as the Max Depth achieved.
Immediate Violation Mode and Gauge Mode
If a ceiling much greater than 60 feet (18 meters) is required, an Immediate Violation
Mode will be entered. This situation would be preceded by entering Delayed Violation
Mode #2.
The VT Pro would then operate with limited functions in Gauge Mode during the remain-
der of that dive and for 24 hours after surfacing. Gauge Mode turns the VT Pro into a
digital instrument without any decompression or oxygen monitoring functions.
Only Current Depth, Max Depth, Elapsed Dive Time, Tank Pressure, and the bar graphs will
be displayed (Fig. 73). The full Tissue Loading Bar Graph and O2 Bar Graph will both
flash as a warning of this condition.
Press the Front (Advance) button to view Temperature and Time of

The VT Pro will also enter an Immediate Violation Mode 5
minutes after reaching the surface from a dive in which a De-
layed Violation occurred.
