SUUNTO HELO2 - Manual (Page 100)

• 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, 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.
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
• Life expectancy at 20°C/68°F:
•
100 dives/year –>1 year
