ALTITUDE SENSING AND ADJUSTMENT
Altitude (i.e., ambient pressure) is measured upon activation and every 15 minutes until a
dive is made.
> Measurements are only taken when the unit is dry.
> Two readings are taken, the second reading 5 seconds after the first. The readings
must be within 1 foot (30 cm) of each other to record that ambient pressure as the
current Altitude.
> No adjustments are made during any time that the Wet Contacts are bridged.
> When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270
meters), the VEO automatically adjusts to these conditions providing corrected Depth,
and reduced No Deco and O2 Times at intervals of 1,000 feet (305 meters).
> When the Conservative Factor is set On, NDLs are calculated based upon the next
higher 3,000 foot (915 meter) Altitude.
> At Sea Level, calculations are based upon an Altitude of 6,000 feet.
> All adjustments for Altitudes greater than 11,000 feet (3,355 meters) are then made
to allowable dive times for 14,000 feet (4,270 meters).
> The VEO will not function as a Dive Computer above 14,000 feet (4,270 meters).
