SUUNTO D9tx - Manual (Page 118)

• Memory capacity: approximately 140 hours of diving with 20 second recording in-
terval
• Depth resolution: 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 Technical 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
• Helium halftimes:1, 2, 3.5, 7.5, 15, 30, 45, 90, 181 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 prin-
ciples.
