Operation Manual

52
WARNING: Aeris recommends the application of responsible
diving practices and does not recommend decompression div-
ing, or diving deeper than 130 feet (39 m), as these practices
will greatly increase your risk of decompression sickness.
Decompression Dive Mode (Fig. 53) activates when the theoretical no decom-
pression limits are exceeded causing the Nitrogen Bar Graph to pass the yel-
low Caution zone and enter the red Decompression zone. The Aeris 300G will
emit a double beep to alert you.
Information displayed includes current Depth, current decompression ceiling
Stop Depth and Time (and ceiling stop icon), and Total Ascent Time that in-
cludes stop times required at all ceilings and vertical ascent time calculated at
60 feet (18 meters) per minute. The ceiling bar of the Decompression Mode
icon will flash continuously. The O2 bar graph (if a nitrox dive) and Ascent
Rate Indicator will continue to represent their respective information.
By pressing the Advance (Left) button, an Alternate Display will appear show-
ing Maximum Depth (and icon) and Elapsed Dive Time (and icon) in the lower
screen (Fig. 54) for button depression time plus 3 seconds after it is released.
The amount of decompression credit time that you receive is dependent on
depth, with slightly less credit given the deeper you are. Still, you must
never ascend shallower than your decompression ceiling. Doing so
