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 two years, or more often depending on dive activity
•
Life expectancy at 20°C/68°F:
•
0 dives/year –> 2 years
•
100 dives/year –>1.5 years
•
300 dives/year –>1 year
Transmitter:
•
One 3V lithium battery: 1/2AA (K5546) and O-ring 2.00 mm x 2.00 mm (K5538)
•
Battery storage time (shelf life): Up to three years
•
Replacement: Every two years, or more often depending on dive activity
