AIR TIME REMAINING BAR GRAPH

The Air Time Remaining Bar Graph (Fig. 48a) displays remaining breathing gas times of 60 minutes and less. As time remaining decreases, segments are removed from the bar graph from the right (green) toward the left (red) in increments of 5 minutes (from 60 to 0 minutes).

When the time decreases to the Alarm set point, the Audible Alarm will emit a beep and the red Warning LED will flash until

aacknowledged. You should begin a safe controlled ascent to the surface.

CONTROL OF DISPLAYS

During No Decompression conditions, various displays of information (up to 4) are available. Each provides Depth, Dive Time Remaining, and additional information. The intent of this feature is to provide the diver control of how much information is on the display at any given time during the dive. The diver can change from one display to another as often as desired by pressing the Left (Advance) button, otherwise it does not change. An exception to this is during a 3 minute no decompression dive Safety Stop (described on page 53).
