INTRODUCTION
Welcome to TUSA and thank you for choosing the Element !
It is extremely important that you read this manual in sequence
and understand it completely before attempting to use the
Element.
Remember that technology is no substitute for common sense,
and a dive computer only provides the person using it with
data, not the knowledge to use it.

CONTROL BUTTON
The Control Button allows you to select display options and access specific information
when you want to see it. It is also used to enter settings.
BAR GRAPHS
Nitrogen Loading Bar Graph (NiBG)
The NiBG (Fig. 1a) represents tissue loading of nitrogen, showing your relative no decom-
pression or decompression status. As your depth and elapsed dive time increase, seg-
ments will add to the NiBG, and as you ascend to shallower depths, the segments will
recede, indicating that additional no decompression time is allowed for multilevel diving.
The Nitrogen Loading Bar Graph monitors 12 different nitrogen compartments simulta-
neously and displays the one that is in control of your dive. It is divided into a No Decom-
pression (normal) zone, a Caution zone (also No Decompression), and a Decompression
(danger) zone.
While you cannot provide a guarantee against the occurrence
of decompression sickness, you may choose your own personal
zone of caution based upon age, physique, excessive weight,
etc., to reduce the statistical risk.
NOTE: Displays associated with oxygen and the O2
Bar Graph will only appear if FO2 has been set at a
value other than 'Air' (e.g., a numerical value).

Oxygen Accumulation Bar Graph (O2BG)
The O2BG (Fig. 2a) represents oxygen accumulation, showing
the maximum of either per dive accumulated oxygen, or 24 hour
period accumulated oxygen.
As your oxygen exposure (accumulation) increases during the
dive, segments will add to the O2BG, and as loading de-
creases, it will begin to recede, indicating that additional
exposure is allowed for that dive and 24 hour period.
Ascent Rate Indicator (ASC)
The ASC (Fig. 2b) provides a visual representation of ascent
speed (i.e., an ascent speedometer).
The segments of the ASC represent two sets of speeds which
change at a reference Depth of 60 FT (18 M). Refer to the chart
for segment values.
WARNING: At depths greater than 60 FT (18 M),
ascent rates should not exceed 60 feet per minute
(18 meters per minute). At depths of 60 FT (18 M)
and shallower, ascent rates should not exceed 30
feet per minute (9 meters per minute).

ALPHA / NUMERIC DISPLAYS
Each numeric and graphic display represents a
unique piece of information. It is imperative that you
understand the formats, ranges, and values of the
information represented to avoid any possible mis-
understanding that could result in error.
Depth Displays
During a dive, the Current Depth display (Fig. 3Aa), indicates
depths from 0 to 330 FT (99.9 M) in 1 FT (0.1 M) increments.
The Maximum Depth reached during that dive is displayed
on an Alternate screen by pressing the button (Fig. 3Ba).
During a No Deco Dive Deep and Safety Stops and while in
Decompression, the required Stop Depth is displayed on the
Main (Fig. 4a).
