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 and its 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 recommenda-

tions by R.W. Hamilton, PhD and currently accepted exposure time

limit tables and principles
