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 200/250 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 200/250 dive computer model is based upon the latest research and experi-
ments in decompression theory. Still, using the Veo 200/250, just as using the U.S. Navy
(or other) No Decompression Tables, is no guarantee of avoiding decompression
sickness, 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.

INTRODUCTION
Welcome to Oceanic and thank you for choosing the Veo 200 or Veo 250 !
It is extremely important that you read this Operating Manual in sequence and understand
it completely before attempting to use the Veo 200/250. It is equally important that you
read the Oceanic Dive Computer Safety and Reference Manual (Doc. No. 12-2262)
provided with your Veo 200/250. It contains information that you must become familiar
with prior to diving with your Veo 200/250.
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.
The Veo 200 and 250 are configured with the same features and functions. The differ-
ence between them is the location of the 2 Control Buttons (page 8). The Veo 200 is
designed for mounting in a Console Boot and has both Buttons on the front. The Veo 250
is designed to wear on the wrist and has 1 button on the front and 1 on the right side.
INTERACTIVE CONTROL CONSOLE
The Control Buttons, referred to as the Interactive Control Console allow you to select
display options and access specific information when you want to see it. They are also
used to enter settings, activate the Backlight, and acknowledge the Audible Alarm.
The Left button of the Veo 200 and Front button of the Veo 250 are referred to as the
Advance button. The Right button of the Veo 200 and Side button of the Veo 250 are
referred to as the Select button. The terms used in this manual are Left/Front (Advance)
and Right/Side (Select) referring to the Veo 200/250.

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 green No Decompres-
sion (normal) zone, a yellow Caution zone (also No Decompres-
sion), and a red 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).
