Displays only in Nitrox mode:

•

Oxygen%: 21 - 50.

•

Oxygen partial pressure display: 1.2 - 1.6 bar depending on the limit

setting.

•

Oxygen Limit Fraction: 1 - 110% with 10% resolution (bar graph).

Logbook/Dive Profi le Memory:

•

Recording interval: 20 seconds (the recording interval can be set to 10s,

30s or 60s with the optional PC-interface unit and software), records the
maximum depth of each interval.

•

Memory capacity: approximately 36 hours of diving with 20 seconds

recording interval.

•

Depth accuracy: 0.3 m [1 ft].

Operating Conditions

•

Normal altitude range: 0 to 3000 m [10000 ft] above sea level.

•

Operating temperature: 0°C to 40°C [32°F to 104°F].

•

Storage temperature: -20°C to +50°C [-4°F to +122°F].

It is recommended that the instrument be stored in a dry place at room

temperature.

NOTE! Do not leave the dive computer in direct sunlight!

Tissue Calculation Model

•

Suunto RGBM algorithm (developed by SUUNTO and Bruce R.

Wienke, BS, MS and PhD).

•

9 tissue compartments.

•

Tissue compartment halftimes: 2.5, 5, 10, 20, 40, 80, 120, 240 and 480

minutes (on gassing). The off gassing halftimes are slowed down.

•

Reduced gradient (variable) “M” values based on diving habit and dive

violations. The “M” values are tracked up to 100 hours after a dive.

•

The EAN and oxygen exposure calculations are based on

recommendations by R.W. Hamilton, PhD and currently accepted
exposure time limit tables and principles.
