DECOMPRESSION DIVE MODE
The XR2 is designed to help you by providing a representation of
how close you are to entering Decompression. Decompression
Dive Mode activates when theoretical No Decompression time/
depth limits are exceeded.
Entry into Deco Dive Mode (Fig. 50)
Upon entering Deco Mode, the Audible Alarm will sound and the
red LED Warning Indicator 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. 50a) and decompress for the Stop Time indicated (Fig. 50b).
Total Ascent Time appears in the lower screen with the Deco Mode
icon (wave/clock/profile/deco bar) (Fig. 50c).
 The UP Arrow and Deco Bar will flash while you are greater
than 10 feet (3 meters) deeper than the Required Stop Depth.
 While within 10 feet (3 meters) of, and below, the Stop Depth,
both Arrows and the Bar appear solid.
 Total Ascent Time includes Stop Times required at all stops 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 less.
