Logbook/Dive Profi le Memory:

• Recording interval: 20 seconds adjustable (1-10-20-30-60s), records the maximumdepth, minimum temperature and minimum tank pressure of each interval.
• Memory capacity: approximately 36 hours of diving with 20 seconds recordinginterval.
• 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 Deepstop 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 recommendationsby R.W. Hamilton, PhD and currently accepted exposure time limit tables andprinciples.

BatteryD9:

• One 3 V lithium battery: CR 2450
• Battery storage time (shelf life): Up to three years.
• Replacement: Every two years or more often depending on dive activity.
• Life expectancy at 20°C [68°F]:
• 0 dives/y -> 2 years
• 100 dives/y -> 1,5 years
• 300 dives/y -> 1 year

The following conditions have an affect on the expected battery lifetime:

• The length of the dives.
• The condition in which the unit is operated and stored (e.g. temperature/coldconditions). Below 10°C [50°F] the expected battery lifetime is about 50-75%of that at 20°C [68°F].
• The use of the backlight and audible alarms.
• Use of the compass
• The quality of the battery (some lithium batteries may exhaust unexpectedlywhich cannot be tested in advance).
• The time the dive computer has been stored until it gets to the customer. Thebattery is installed into the unit at the factory.
