•
Reduced gradient (variable) "M" values based on diving habit and dive violations.

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,
