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),
Air Time Remaining (U.S. Patent no. 4,586,136), 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 Pro Plus 2 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 Pro Plus 2 dive computer
model is based upon the latest research and experiments in decompression theory. Still, using the Pro Plus 2, just
as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decom-
pression 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 Pro Plus 2 !
It is extremely important that you read this Operating Manual in sequence and under-
stand it completely before attempting to use the Pro Plus 2.
It is equally important that you read the Oceanic Dive Computer Safety and Reference
Manual (Doc. No. 12-2262) provided with your Pro Plus 2. It contains information that
you must become familiar with prior to diving with your Pro Plus 2.
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.
INTERACTI E CONTROL CONSOLE
The Interactive Control Console consists of two Control Buttons
that 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 is referred to as Advance (Fig. 1a) and the
Right button as Select (Fig. 1b).

BAR GRAPHS
Tissue Loading Bar Graph (TLBG)
The Tissue Loading Bar Graph (Fig. 2a) represents tissue
loading of nitrogen, showing your relative no decompression
or decompression 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 Decom-
pression (normal) zone, a yellow Caution zone (also No
Decompression), and a red Decompression (danger) zone.
While you cannot provide a guarantee against the occur-
rence of decompression sickness, you may choose your own
personal zone of caution based upon age, physique, exces-
sive 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). Fig. 2 - TLBG

Oxygen Accumulation Bar Graph (O2BG)
The O2 Bar Graph (Fig. 3a) represents oxygen loading, 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 Bar Graph, and as loading decreases, it will begin to recede, indicating that addi-
tional exposure is allowed for that dive and 24 hour period.
ariable Ascent Rate Indicator ( ARI)
The Variable Ascent Rate Indicator (Fig. 3b) provides a visual representation of ascent
speed (i.e., an ascent speedometer). Green is a 'normal' rate, yellow a 'caution' rate,
and red is 'Too Fast'. The segments of the VARI represent two sets of speeds which
change at a reference depth of 60 feet (18 meters). Refer to the chart (Fig. 4) for seg-
ment values.

WARNING: At depths greater than 60 feet (18
meters), ascent rates should not exceed 60 fpm (18
mpm). At depths of 60 feet (18 meters) and shallower,
ascent rates should not exceed 30 fpm (9 mpm).
