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: 3.7 V rechargeable lithium-ion
• Charging: USB: 5 Vdc, 0.8 A
• Battery life: fully charged, min. 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.

Radio transreceiver

• Bluetooth® Smart compatible
• Frequency band: 2402–2480 MHz
• Maximum output power: <4 dBm
• Range: ~3 m / 9.8 ft

Underwater radio receiver

• Frequency band: single channel 123 kHz
• Range: 1.5 m / 4.9 ft
