DECOMPRESSION DIVE MODE
The Pro Plus 2 is designed to help you by providing a repre-
sentation of how close you are to entering Decompression.
Decompression Dive Mode (Fig. 55) activates when theoreti-
cal No Decompression time/depth limits are exceeded.
Upon entering Decompression Mode, the Audible Alarm will
sound and the red LED Warning Light will flash for 10
seconds (unless set OFF), or until acknowledged.
Press and hold the Left (Advance) button for 2 seconds to
acknowledge/silence the Audible Alarm (unless set OFF).
The UP Arrow and Deco Bar will flash if you are greater
than 10 feet (3 m) deeper than the Required Stop Depth.
Once you are within 10 feet (3 m) of, and below, the
Stop Depth, both Arrows and the Bar appear solid.
Total Ascent Time
Total Ascent Time (Fig. 55a) includes Stop Times required at
all required decompression 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.
