Testing
• Activate the unit and ensure that the LCD is clear and sharp in contrast. If any portions are missing or appear dim, or if a low battery condition is
indicated, return the GEO AIR to an authorized Oceanic dealer for evaluation before use.
• Verify all set points prior to diving.
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 GEO AIR automatically adjusts to these conditions pro-
vidingcorrected 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 GEO AIR will not function as a Dive Computer above 14,000 feet (4,270 meters).
