PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Dive Time Remaining (U.S. Patent no. 4,586,136), Data Sensing and Processing Device (U.S. Patent
no. 4,882,678), and Variable Ascent Rate Indicator (U.S. Patent no. 5,156,055). User Setable
Display (U.S. Patent no. 5,845,235) is owned by Suunto Oy (Finland).
DECOMPRESSION MODEL
The programs within the Veo 100Nx simulate the absorption of nitrogen into the body by using a
mathematical model. This model is merely a way to apply a limited set of data to a large range of
experiences. The Veo 100Nx dive computer model is based upon the latest research and experiments
in decompression theory. Still, using the Veo 100Nx, just as using the U.S. Navy (or
other) No Decompression Tables, is no guarantee of avoiding decompression sick-
ness, i.e. the bends. Every divers physiology is different, and can even vary from day to day.
No machine can predict how your body will react to a particular dive profile.

FEATURES and DISPLAYS
WARNING: Prior to iving with the Veo 100Nx, you must also

INTRODUCTION
Welcome to Oceanic and thank you for choosing the Veo
100Nx !
It is extremely important that you read this Operating Manual in
sequence and understand it completely before attempting to use
the Veo 100Nx.
It is equally important that you read the Oceanic Dive Computer
Safety and Reference Manual (Doc. No. 12-2262) provided
with your Veo 100Nx. It contains information that you must
become familiar with prior to diving with your Veo 100Nx.
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
Tissue Loa ing Bar Graph (TLBG)
The Tissue Loading Bar Graph (Fig. 1a) represents tissue loading
of nitrogen, showing your relative no decompression or decom-
pression status. As your depth and elapsed dive time increase,
segments will add to the Graph, and as you ascend to shallower
depths, the Bar Graph will begin to recede, indicating that
additional no decompression time is allowed for multilevel
diving.
The Tissue Loading Bar Graph monitors 12 different nitrogen
compartments simultaneously and displays the one that is in
control of your dive. It is divided into a No Decompression
(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 associate with oxygen an 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 O2 Bar Graph (Fig. 2a) represents oxygen loading, show-
ing 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 Bar Graph, and as loading
decreases, it will begin to recede, indicating that additional
exposure is allowed for that dive and 24 hour period.
Variable Ascent Rate In icator (VARI)
The Variable Ascent Rate Indicator (Fig. 2b) provides a visual
representation of ascent speed (i.e., an ascent speedometer).
The segments of the Variable Ascent Rate Indicator 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 epths greater than 60 FT (18 M),
ascent rates shoul not excee 60 feet per minute
(18 meters per minute). At epths of 60 FT (18 M)
an shallower, ascent rates shoul not excee 30
feet per minute (9 meters per minute).
