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.
• 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).
