DECOMPRESSION MODEL
The programs within the Pro Plus 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 dive computer model is based upon the latest research and experiments in decompression
theory. Still, using the Pro Plus, 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.

The Pro Plus has a wide array of features described in detail throughout the
pages that follow. Due to the importance that they be understood thoroughly
prior to using the Pro Plus, information will be expanded upon and some refreshed as you proceed. Relax and read through the complete guide.
It is extremely important that you read this owner's guide in sequence and understand it completely before attempting to use the
Pro Plus.
Remember that technology is no substitute for common sense, and a dive com-
Pro PLUS
puter only provides the person using it with data, not the knowledge to use it.
INTERACTIVE CONTROL CONSOLE
The Interactive Control Console, consisting of the Advance (Left) button and
Select (Right) button (Fig. 1), allows you to select various display options and
access specific information when you choose to see it. The buttons can be
pressed repeatedly, or held in to scroll.
INFORMATIONAL DISPLAYS
Operational modes and status information are visually represented numerically and/or graphically and can be understood at a glance with the aide of universal icons (Fig. 2) that identify and bring quick focus to the displays. Segmented bar graphs will show how close you are to critical limits.
Each Pro Plus 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 misunderstanding that could result in error.
NOTE: Throughout this owner's guide reference is made to the
term ''breathing gas'. The rational being that the Pro Plus can
be used for 'air' dives or 'nitrox' dives. For clarity these terms
are defined as -
Breathing Gas - the gaseous mixture breathed during a dive.
Air - a breathing gas that contains approximately 21% oxygen
and 79% nitrogen (nature's common nitrogen-oxygen mixture).
Nitrox - a nitrogen-oxygen breathing gas that contains a higher
fraction of oxygen (22 to 50%) than air.

UNIVERSAL GRAPHIC DIVER INTERFACE
C Z O
™
Four bar graphs referred to as the Universal Graphic Diver Interface™ appear
around the perimeter of the screens (Fig. 3). These segmented bar graphs are
2
located next to green, yellow, and red color coded portions of the peripheral
decal that denote normal, caution, and danger zones, respectively.
When underwater, you can quickly focus on the bar graphs to make sure that
they are in the green. You can quickly verify that you're not getting too close
to the no decompression limit or the limit for exposure to oxygen (accumulation), or ascending too fast.
Tissue Loading Bar Graph
C Z O
The Tissue Loading Bar Graph™ (TLBG) represents nitrogen loading (Fig. 4),
showing your relative no decompression or decompression status. As your
™
depth and elapsed dive time increase, segments will add to the graph beginning in the lower left portion of the screen. As you ascend to shallower depths,
2
this 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 Decompression zone (NO DECO), a yellow Caution zone
(C.Z.), and a red Decompression zone (DECO). The bar graph gives a visual
representation of just how close you are to the no decompression limit with a
yellow Caution (C.Z.) Zone that allows you to make a decision regarding safety
stop duration or necessity. The Tissue Loading Bar Graph™ has been granted
U.S. Patent No. 4,882,687.
The Tissue Loading Bar Graph™ also assists you with managing decompression (explained later) by filling a large red 'ceiling stop required' segment.
Oxygen Accumulation (O2) Bar Graph
NOTE: Displays associated with oxygen and the O2 bar graph
will only appear if FO2 has been set at a value other than 'Air'.
Datamax Pro Plus
The Oxygen Accumulation (O2) Bar Graph (Fig. 5) represents oxygen loading,
your relative oxygen tolerance dosage (OTU), showing the maximum of either
per dive accumulated oxygen, or 24 hour period accumulated oxygen. As your
exposure (accumulation of oxygen) increases during the dive, segments will
add to the bar graph starting in the lower right portion of the screen. As oxygen loading decreases, the bar graph will begin to recede, indicating that additional exposure (accumulation) is allowed for that dive, and 24 hour period.
The O2 bar graph also assists you with managing high partial pressure of oxygen (PO2) by flashing the large red Danger zone segment as a warning when
the level of PO2 exceeds the maximum allowed limit of 1.60 ATA.

Variable Ascent Rate Indicator™ (VARI)
The Variable Ascent Rate Indicator™ (Fig. 6a) is provided to help you avoid
excessive ascent rates by displaying a visual representation of ascent speed,
rather than just showing that you are ascending too fast. The Variable Ascent
Rate Indicator has been granted U.S. Patent no. 5,156,055.
The 5 triangular segments of the bar graph, located beside green, yellow, and
red reference zones, appear beginning from the left and may be considered an
ascent rate speedometer. Green is a 'normal' rate, yellow is a 'caution' rate,
and red is 'Too Fast'.
In the event that your ascent rate exceeds the maximum recommended rate of
60 feet (18 meters) per minute, the bar graph segments will enter the red zone
and all 5 segments will flash once per second until your ascent speed is slowed.
If this occurs, you should immediately slow your ascent.

Breathing Gas Time Remaining Bar Graph
The Breathing Gas Time Remaining Bar Graph located along the bottom of
the lower display (Fig. 6b) provides a graphic representation of the time that
you can remain at your present depth and then, following a safe ascent, surface with a predetermined breathing gas reserve. This calculation and display
is based on your breathing gas consumption rate that is continually monitored
by the Pro Plus, and it takes into account the breathing gas required for a safe
ascent including any required decompression stops.
The green, yellow, and red zones adjacent to the bar graph enable you to
quickly focus on remaining breathing gas times of 60 minutes or less, based on
your pre selected End Gas Alarm Set Point. The bar graph is more precise as
time remaining decreases toward the red zone.
DIVE TIME REMAINING
One of the most important pieces of information on the Pro Plus is the 'Dive
Time Remaining numeric display'. The Pro Plus constantly monitors three
critical pieces of information; no decompression status, oxygen accumulation
status, and rate of breathing gas consumption. The Dive Time Remaining display will indicate the time that is more critical for you at that particular moment (i.e.; whichever time is the least amount available of the three). The specific time being displayed is identified by the No Decompression Dive Time
icon, or the O2 Time icon, or the Gas Time Remaining icon (Fig. 7). This
unique feature has been granted U.S. Patent No. 4,586,136.

It is calculated based on the amount of nitrogen absorbed by twelve hypothetical tissue compartments. The rates each of these compartments absorb and
release nitrogen is mathematically modeled and compared against a maximum
allowable nitrogen level. Whichever one of the twelve is closest to this maximum level is the controlling compartment for that depth. Its resulting value
will be displayed numerically (Fig. 8a) along with the No Decompression Dive
icon and graphically as the Tissue Loading Bar Graph.
As you ascend from depth following a dive that has approached the no decompression limit, the Tissue Loading Bar Graph will recede as control shifts to
slower compartments. This is a feature of the decompression model that is the
basis for multilevel diving, one of the most important advantages the Pro Plus
offers.

The no decompression algorithm is based upon Haldane’s theory using maximum allowable nitrogen levels developed by Merrill Spencer. Repetitive diving
control is based upon experiments designed and conducted by Dr. Ray Rogers
2
and Dr. Michael Powell in 1987. Diving Science and Technology® (DSAT), a
corporate affiliate of PADI®, commissioned these experiments.

Oxygen Accumulation Time Remaining
Oxygen accumulation (exposure) during a dive, or 24 hour period, appears
graphically as the Oxygen Accumulation (O2) Bar Graph. As time remaining
before reaching the oxygen exposure limit decreases, segments are added to
the O2 bar graph. When the amount of time remaining before reaching the
oxygen limit becomes less than the No Decompression Dive Time Remaining,
or Breathing Gas Time Remaining, calculations for that depth will be controlled by oxygen. Oxygen Time Remaining will then appear as the main numeric time display (Fig. 9a) as signified by the O2 Time icon (Fig. 9b) appearing on the display. As oxygen accumulation continues to increase, the O2 bar
graph will enter the yellow Caution Zone (described later).
Breathing Gas Time Remaining
Breathing Gas Time Remaining will appear as the numeric Dive Time Remaining display (Fig. 10) only when it is less than No Decompression Time Remaining and Oxygen Accumulation Time Remaining. Breathing Gas Time Remaining of 60 minutes, or less, will be displayed continuously as the Gas Time Remaining Bar Graph (Fig. 10a) regardless of which time is being displayed as
the numeric Dive Time Remaining. The bar graph represents only Breathing
Gas Time information and it will be the only indication of breathing gas time
remaining if you are in a decompression or violation mode.
The Pro Plus calculates Breathing Gas Time Remaining using a patented algorithm that is based on a diver's individual breathing gas consumption rate and
depth. Tank pressure is measured once each second, and an average rate of
consumption is calculated over a 90 second period. This rate of consumption is

then used in conjunction with a knowledge of the depth dependence to predict
the breathing gas required for a safe ascent including any required decompression stops.
Breathing gas consumption and depth are continuously monitored, and
Breathing Gas Time Remaining reflects any change in your circumstances.
For example, when a buddy starts breathing from your octopus or you suddenly find yourself swimming against a strong current and begin breathing
more rapidly, the Pro Plus will recognize this change and adjust your Breathing Gas Time Remaining accordingly.
Remember, the Breathing Gas Time Remaining is the time you can remain at
the present depth and still surface with the tank pressure reserve (Gas Alarm
Set Point) that you set during setup. When Gas Time Remaining indicates
zero, you should immediately initiate a controlled ascent. There is no reason
to panic, the Pro Plus has allowed for the breathing gas necessary for a safe
ascent including any emergency decompression stops.

During situations that may pose potential danger, one Double Beep is emitted. These situations are:
• Entry into decompression.
• Decreasing to 5 minutes of Breathing Gas Dive Time Remaining.
• Partial pressure of oxygen equal to or greater than 1.40 ATA.
When the Pro Plus senses immediate danger to you, it emits One Beep per
Second until the situation is corrected (if the Audible Alarm feature is set
ON). If the Audible Alarm feature is set OFF (described later), you will be
alerted instead by one Double Beep. Situations are:
• Descent deeper than the Depth Alarm Set Point.
• Ascent to a depth shallower than a required stop depth.
• Ascent rate that exceeds 60 ft./min (18 m/min).
• Gas Time Remaining equals zero (0:00).
• Partial pressure of oxygen equal to or greater than 1.60 ATA.
• Oxygen accumulation equal to or greater than the allowed per dive or 24
hour limit.
If you enter a Delayed or Immediate Violation Mode, a Single Long Beep will
be emitted. This will occur if:
• Depth is shallower than the required stop depth for more than 5 minutes.
• Required Decompression exceeds a 60 FT/ 18 M ceiling.

Immediately following activation and a diagnostic check the Pro Plus will emit
a Short Beep.
Upon reaching the Turn Gas Alarm set point (described later), Six Beeps will
be emitted.

BACKLIGHT FEATURE
In addition to using a high contrast LCD for easy readability in low light conditions, the backlight features evenly illuminate the full upper and lower displays.
Smart Glo™, the surface mode backlight, senses the intensity of light that is
passing through small ports located between the control buttons (Fig. 13). If a
low level of light is sensed, the Smart Glo™ backlight will illuminate the display for button depression time plus 10 seconds when either button is pressed.
Oceanglo®, the dive mode backlight, will illuminate the displays for button depression time plus 5 seconds when the Select (Right) control button is pressed.
Additional illumination time can be obtained by pressing the button again.

NOTE: Extensive use of the backlight reduces estimated battery life. Also, the backlight will not activate during a 'low battery condition', or when downloading data to a PC.
OPERATING TEMPERATURE
The Pro Plus will operate in almost any temperature diving environment in
the world between 32 and 140 °F (0 and 60 °C).
At extremely low temperatures, the LCD may become sluggish, but this will
not affect it's accuracy. If stored or transported in extremely low temperature
areas (below freezing), you should warm the module and its battery with body
heat before diving.
Even though the Pro Plus will operate in this wide range of temperatures, it is
possible to damage the electronics if left exposed to direct sunlight,
or in a hot confined space (like a car trunk). After the dive, cover the
Pro Plus and keep it out of the sun. If inadvertently left in the direct sunlight for a long period, the LCD display may become totally black. If this occurs, immediately immerse the Pro Plus in water. The display should recover
its normal appearance after a few minutes. Damage from excess heat, or
cold, is not covered by the Pro Plus two year limited warranty.

WARNINGS and SAFETY RECOMMENDATIONS
• Inspect your Pro Plus prior to every dive, checking for any signs of the entrance of moisture,
damage to the housing, or damage to the LCD display. If these or other signs of damage are
found, return the unit to an Authorized Oceanic Dealer. DO NOT attempt to use it until it
has received factory service.
• Oceanic advocates responsible diving practices consistent with your individual level of formal training and experience, and does not recommend decompression diving or diving below
130 feet (39 m).
• Always carry primary and backup dive lights when conducting dives that could include low
light situations.
• You should never, under any circumstances, swap your computer with another unit between
dives, or share your computer with another diver underwater. It is impossible for two divers
to stay precisely together underwater, and your computer's dive profile tracking of previous
dives will be pertinent to you only. Nitrogen and oxygen loading of a second user may be significantly different and thus swapping dive computers could lead to inaccurate and potentially dangerous predictions of decompression and oxygen accumulation status. This rule
applies to the use of all dive computers, but is especially important when using the Pro Plus,
due to the personal information it provides.

ACTIVATION
Connect the regulator assembly to a full cylinder and pressurize by slowly
opening the cylinder valve. Note that to enter settings, access information
such as the log, or to download data it is not necessary to pressurize the unit.
To activate the Pro Plus, press the Select (Right) button once and release. It
will immediately enter Diagnostic Mode, displaying all “8’s” (Fig. 14), followed
by “dashes”, and a countdown from 9 to 0. While conducting diagnostics, the
displays are illuminated by the Smart Glo™ backlight as display functions and
battery voltage are checked to ensure that everything is working correctly.
Upon activation, the Pro Plus will also check the ambient barometric pressure,
and calibrate its present depth as zero. At elevations of 2,000 feet (610
meters), or higher, it will recalibrate itself to measure depth in feet of fresh
water instead of feet of sea water.
If no dive is made within 2 hours after initial activation, the Pro Plus will automatically deactivate to conserve its battery power. Always check the dis-
play before entering the water to ensure that it is activated.
18
SURFACE MODE
Surface Mode, identified by the Surface Time icon (Fig. 15a), immediately follows Diagnostic Mode after initial activation. Information displayed includes
the Dive Number '0' (no dive made yet), Surface Time with flashing colon, and
cylinder pressure.
If battery voltage is below the level sufficient for a day's operation, the Battery
icon will be displayed (Fig. 16a). Below 15% of rated voltage, all graphic displays will shut off except the Battery icon that will flash for 4 seconds, then
the unit will shutdown.

Before going diving, enter settings that will be common for each of your dives
(e.g., Units of Measure, etc.). This will save you time at the dive site.
Setting the FO2 value for a nitrox mix is a 'pre dive' setting that is entered before nitrox dives. This is described on page 34.
As described later, some of the settings will have to be reentered when the battery is replaced
ENTERING SETTINGS
• The Advance (Left) button is used to gain access to settings.
• The Select (Right) button is used to toggle between, or scroll through, the
individual set points available for each of the settings.
• The Advance (Left) button is then used to accept and save the set point
and revert to Surface Mode, or continue to the next setting.
• See page 30 for a 'Summary of Access to Set Modes' that also
notes 'settings entered by the factory'.
NOTE: While in the Set Mode, if neither button is pressed, the
unit will automatically revert to Surface Mode in 2 minutes.
