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: up to 6-12 h diving or 6 days in time mode

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)
