SURFACING
Upon ascending to 3 ft (0.9 m) the Geo 4.0 transitions to Dive Surface mode.
NOTE: The Geo 4.0 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 4.0 memory.

WARNING: Historically, many accidents and near misses have occurred by switching to the wrong gas at the wrong depth. DO
NOT attempt gas switch decompression dives without proper education and training to do so from an internationally recognized
training agency.
Overview
• All dives begin with GAS 1.
• The GAS defaults to # 1 after 10 minutes on the surface.
• Gas switches can only be made when a Dive Main screen is displayed.
• 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.

If the current PO2 value is greater than 1.6, then a warning not to switch will display. The Geo 4.0 will maintain the current gas without switching.
The diver may override the Geo 4.0 and force the gas switch by pressing the SELECT button during the "dont CHNG TO" 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 drowning. Always dive
within your training, experience, and skill level.
