DECOMPRESSION DIVE MODE
The ATMOS ai is designed to help you by providing a representation of how close you are to en-
tering decompression. Decompression Dive Mode activates when theoretical No Decompression
time/depth limits are exceeded.
Entry into Decompression Dive Mode
(Fig. 49)
Upon entering Decompression Mode, the Audible Alarm will sound and the red LED Warning In-
dicator will flash for 10 seconds (unless set OFF), or until acknowledged.
At that time, you should begin a safe controlled ascent to a depth slightly deeper than, or equal to,
the Required Stop Depth indicated (Fig. 49a) and decompress for the Stop Time indicated (Fig.
49b).
The UP Arrow and Deco Bar will flash if you are greater than 10
feet (3 meters) deeper than the Required Ceiling Stop Depth.
While within 10 feet (3 meters) of, and below, the Stop Depth,
both Arrows and the Bar appear solid.
Other information includes:
Current Depth (Fig. 49c).
Total Ascent Time (Fig. 49d) - which includes Stop Times re-
quired at all ceilings and vertical Ascent Time calculated at 60 feet
(18 meters) per minute for depths deeper than 60 feet (18 meters),
and 30 feet (9 meters) per minute for depths of 60 feet (18 meters)
and shallower.
