BAR GRAPHS
Two segmented Bar Graphs appear around the perimeter of the screen next to green, yellow, and
red color coded portions of the peripheral decal that denote normal, caution, and danger zones, re-
spectively.
When underwater, you can quickly focus on the bar graphs to make sure that they are in the
green and you are not getting too close to the no decompression limit or ascending too fast.
Ascent Rate Indicator (ARI)
The Ascent Rate Indicator located along the bottom of the LCD (Fig. 3a) is provided to help you
avoid excessive Ascent Rates by providing a visual representation of ascent speed, rather than just
showing that you are ascending too fast.
The LCD displays up to 5 segments that may be considered an Ascent Rate speedometer. Green
is a 'normal' rate, yellow a 'caution' rate, and red is 'Too Fast'. The segments of the Ascent Rate
Indicator represent 2 sets of speeds which change at a reference depth of 60 FT (18 M). Refer to
the chart at the right for segment values.
When your ascent rate exceeds the maximum recommended rate of 60 FPM (18 MPM) when
deeper than 60 FT (18 M) or 30 FPM (9 MPM) when shallower than 60 FT (18 M), the bar graph
segments will enter the red 'Too Fast' zone at which time the Audible Alarm will sound and all 5
segments will flash once per second until your ascent speed is slowed.
