• 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 principles
Battery:
• One 3 V lithium battery: CR 2450
• Battery storage time (shelf life): Up to three years
• Replacement: Every three years, or more often depending on dive activity
• Life expectancy at 20°C/68°F:
• 0 dives/y - 3 years
• 100 dives/year – 2 years
• 300 dives/year – 1.5 years
The following conditions have an effect on the expected battery lifetime:
•
The length of the dives
•
The conditions in which the unit is operated and stored (e.g. temperature/cold
conditions). Below 10°C/50°F the expected battery lifetime is about 50-75% of that
at 20°C/68°F
•
The use of the backlight and audible alarms
•
The use of the compass
•
The quality of the battery. (Some lithium batteries may exhaust unexpectedly,
which cannot be tested in advance)
•
The time the dive computer has been stored until it gets to the customer. (The
battery is installed in the unit at the factory)
