Tissue calculation model
- Suunto Fused™ RGBM 2 algorithm (developed by Suunto and Bruce R. Wienke, BSc, MSc, PhD)
- 15 tissue compartments
- Tissue compartment halftimes for nitrogen: 1, 2, 5, 10, 20, 40, 80, 120, 160, 240, 320, 400, 480, 560 and 720 min. The on-gassing and off-gassing halftimes are the same.
- Tissue compartment halftimes are divided by a constant factor to obtain helium halftimes.
- 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 exposure calculations (CNS% and OTU) are based on recommendations by R.W. Hamilton, PhD and currently accepted exposure time limit tables and principles.
Battery
- Type: rechargeable lithium-ion
- Battery life: fully charged, 10–20 h dive time
The following conditions have an effect on the expected battery lifetime:
- The conditions in which the unit is operated and stored (for example, temperature/cold conditions). Below 10 °C/50 °F the expected battery lifetime is about 50–75% of that at 20 °C / 68 °F.
- The quality of the battery. Some lithium batteries may exhaust unexpectedly, which cannot be tested in advance.
NOTE:
Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. The battery should be replaced only by authorized Suunto Service Centers.
NOTE:
Low temperature may activate the battery warning even though the battery has enough capacity for diving in water with higher temperatures (40 °C or less).
