Doc. No. 12-5673-r05 (10/11/22)
If the current PO2 value is greater than 1.6, then a warning not to switch will display. The GEO AIR will maintain the current gas without switching.
The diver may override the GEO AIR and force the gas switch by pressing the SELECT button during the "STOP Gas PO2 1.XX" message.
WARNING: Switching to gases with a PO2 above 1.6 has a high risk of oxygen poisoning, convulsions, and drowning.
Doing so should always be avoided. It is intended as a last resort option because of the likelihood of injury or drown-
ing. Always dive within your training, experience, and skill level.

COMPLICATIONS
The preceding information has described standard dive operations. Your new GEO AIR is also designed to help you to the surface in less than ideal
situations. The following is a description of these situations. Take some time to familiarize yourself with these operations before diving your GEO AIR.
DECOMPRESSION
Decompression (deco) mode activates when theoretical No Decompression time and depth limits are exceeded. Upon entry into decompression, the
audible alarm will sound and the alarm LED will flash. The full Tissue Loading Bar Graph and Up Arrow icon will flash until the audible is silenced.
• Once within 10 ft (3m) below the required Stop Depth (stop zone), the Full Stop icon (both Arrows with Stop Bar) will be displayed solid.
To fulfill your decompression obligation, you should make a safe controlled ascent to a depth slightly deeper than, or equal to, the required stop
depth indicated and decompress for the stop time indicated. The amount of decompression credit time that you receive is dependent on Depth, with
slightly less credit given the deeper you are below the Stop Depth indicated. You should stay slightly deeper than the required Stop Depth indicated
until the next shallower Stop Depth appears. Then you can slowly ascend to that indicated Stop Depth but not shallower.
DECOMPRESSION ENTRY
Upon entry into decompression (deco) the audible alarm will sound and the alarm LED will flash until the audible is silenced. The up arrow and full
Tissue Loading Bar Graph icons will flash. Additionally, the stop depth and stop time values will be displayed. TTS (Time To Surface), available on an
alt screen, includes stop times at all required Decompression Stops plus vertical ascent time based on the max ascent rate allowed.

GAS SWITCH WARNING
If gas 2 (3) is set on and the current gas is not the best gas when approaching the decompression stop zone, the Geo Air will warn you to switch
gases. You must confirm the gas switch by pressing the SELECT button. If the gas switch is not confirmed within 30 seconds, no switch will be made.
Though you may still manually switch gases at any time throughout the dive by using the Gas Switch menu.
