SURFACING
Upon ascending to 3 ft (0.9 m) the GEO AIR transitions to Dive Surface mode.
NOTE: The GEO AIR requires a 10 minute surface interval to record a subsequent dive as a separate dive in the Log.
Otherwise, the dives will be combined and recorded as a single dive in the GEO AIR memory.

WARNINGS:
• Historically, many accidents and near misses have occurred by switching to the wrong gas at the wrong depth. DO NOT at-
tempt gas switch decompression dives without proper education and training to do so from an internationally recognized
training agency.
• Diving deeper than 39 m (130 ft), will greatly increase your risk of decompression sickness.
• Decompression diving is inherently hazardous and greatly increases your risk of decompression sickness, even when per
-
formed according to the dive computer's calculations.
• Using an Geo Air is no guarantee of avoiding decompression sickness.
• The Geo Air enters Violation Mode when a situation exceeds its capacity to predict an ascent procedure. These dives rep-
resent gross excursions into decompression that are beyond the boundaries and spirit of the Geo Air's design. If you are
following these dive profiles, Oceanic advises that you should not use a Geo Air.
• If you exceed certain limits, the Geo Air will not be able to help you get safely back to the surface. These situations exceed
tested limits and can result in loss of some functions for 24 hours after the dive in which a violation occurred.
Overview
• All dives begin with GAS 1.
• The active gas defaults to GAS 1 after 10 minutes on the surface.
• Gas switches can only be made when gas 2 is set on.
• Gases cannot be switched while on the surface.
• The Gas Switch Menu cannot be accessed during the sounding of alarms.
• If an alarm strikes while in the Gas Switch Menu, the switch operation is terminated (reverting to the Dive Main screen).
