M2 USER MANUAL
Average depth, calculated from the beginning of the dive or from the time of reset.
Closed Circuit Rebreather.
Central Nervous System oxygen toxicity.
Desaturation time. The time needed for the body to completely eliminate any
nitrogen taken up during diving.
The time spent below a depth of 0.8m/3ft.
Refers to the main gas that is set for the ZH-L8 ADT MB algorithm.
The time in the local time zone.
Maximum depth reached during the dive.
Microbubble. Microbubbles are tiny bubbles that can build up in a diver's body
during and after a dive.
One of the six steps, or levels, in SCUBAPRO's customizable algorithm.
Maximum Operating Depth. This is the depth at which the partial pressure of
oxygen (ppO ) reaches the maximum allowed level (ppO

the MOD will expose the diver to unsafe ppO
Refers to a dive in which more than one breathing gas is used (air and/or nitrox).
A breathing mix made of oxygen and nitrogen, with the oxygen concentration
being 22% or higher. In this manual, air is considered as a particular type of
nitrox.
Minimum amount of time the diver should wait before taking a plane.
This is the time that a diver can stay at the current depth and still make a direct
ascent to the surface without having to perform decompression stops.
Oxygen.
Oxygen concentration used by the dive computer in all calculations.
Profile Dependent Intermediate Stop is an additional deep stop which is
suggested by the M2 at depth where the 3rd or 4th compartment starts off-
gassing.
Partial pressure of oxygen. This is the pressure of the oxygen in the breathing
mix. It is a function of depth and oxygen concentration. A ppO
1.6bar is considered dangerous.
The maximum allowed value for ppO
defines the MOD.
The act of pressing and releasing one of the buttons.
The act of pressing and holding one of the buttons for 1 second before releasing it.
Surface interval. Elapsed time since your last dive ended.
The result of having completed a dive without respecting all mandatory
decompression obligations.
A stopwatch. To time certain steps of the dive.
Universal Time Coordinated, refers to time zone changes when traveling.
