Temperature display:

•Resolution: 1°C/1°F

•Display range: -20 to +50°C/-9 to +122°F

•Accuracy: ± 2°C/± 3.6°F within 20 minutes of temperature change

Calendar clock:

•Accuracy: ± 25 s/month (at 20°C/68°F)

•12/24 h display

Displays only in NITROX mode:

•Oxygen %: 21 - 99

•Oxygen partial pressure display: 0.2 - 3.0 bar.

•Oxygen Limit Fraction: 1 - 200% with 1% resolution

Logbook/dive profile memory:

•Recording interval: 20 seconds adjustable (1,10,20,30,60s).

•Memory capacity: approximately 42 hours of diving with 20 second recording interval

•Depth accuracy: 0.3 m/1 ft

Operating conditions:

•Normal altitude range: 0 to 3,000 m/10,000 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 Deep Stop RGBM algorithm (developed by Suunto and Bruce R. Wienke, BSc, MSc, 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

Battery:

•One 3 V lithium battery: CR 2450

•Battery storage time (shelf life): Up to three years

•Replacement: Every three years, or more often depending on dive activity
