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
