PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Graphic Diver Interface, Pre Dive Planning Sequence, Dive Time Remaining, Depth Alarm Set Point, Smart Glo, Mode Menu Structure, Data Sensing and
Processing Device (U.S. Patent no. 4,882,678), Tissue Loading Bar Graph (U.S. Patent no. 4,882,687), and Variable Ascent Rate Indicator Bar Graph (U.S.
Patent no. 5,156,055).
DECOMPRESSION MODEL
The programs within the Data 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 Data Plus 2 dive computer model is based upon the latest research and experiments in decompression
theory. Still, using the Data Plus 2, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompres-
sion 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 Data Plus 2 !
The Data Plus 2 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 Data Plus 2, 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 se-
quence and understand it completely before attempting to use the
Data Plus 2.
Remember that technology is no substitute for common sense, and a dive com-
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 numeri-
cally and/or graphically and can be understood at a glance with the aide of uni-
versal icons (Fig. 2) that identify and bring quick focus to the displays. Seg-
mented bar graphs will show how close you are to critical limits.
Each Data Plus 2 numeric and graphic display represents a unique
piece of information. It is imperative that you understand the for-
mats, 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 Data Plus 2
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
™
Three bar graphs referred to as the Universal Graphic Diver Interface
™
appear
around the perimeter of the screen (Fig. 3). These segmented bar graphs are
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 (accumula-
tion), or ascending too fast.
Tissue Loading Bar Graph
™
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 begin-
ning in the lower left portion of the screen. As you ascend to shallower depths,
this bar graph will begin to recede, indicating that additional no decompres-
sion 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 di-
vided 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.
This Caution Zone portion of the bar graph allows you to make a decision re-
garding safety stop duration or necessity. While you cannot provide a guaran-
tee 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.
The Tissue Loading Bar Graph also assists you with managing decompression
(explained later) by filling a large red 'ceiling stop required' segment.
The Tissue Loading Bar Graph
™
has been garanted U.S. Patent No. 4,882,687.
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'.
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 oxy-

gen loading decreases, the bar graph will begin to recede, indicating that addi-
tional exposure (accumulation) is allowed for that dive, and 24 hour period.
The O2 bar graph also assists you with managing high partial pressure of oxy-
gen (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
™
The Variable Ascent Rate Indicator™ (VARI), located along the top of the
screen (Fig. 6), is provided to help you to avoid excessive ascent rates by pro-
viding 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.

Rate Indicator
Segments = Speed (rate)
0 = 0 - 20 fpm (0 - 6 mpm)
1 = 21 - 30 fpm (6.5 - 9 mpm)
2 = 31 - 40 fpm (9.5 - 12 mpm)
3 = 41 - 50 fpm (12.5 - 15 mpm)
4 = 51 - 60 fpm (15.5 - 18 mpm)
5 = 61+ fpm (18.5+ mpm)
(when 5, all will flash)

DIVE TIME REMAINING
One of the most important pieces of information on the Data Plus 2 is the pat-
ented Dive Time Remaining numeric display. To numerically display Dive Time
Remaining, the Data Plus 2 constantly monitors two critical pieces of informa-
tion; no decompression status and oxygen accumulation status. The Dive Time
Remaining display will indicate the time that is more critical for you at that par-
ticular moment (i.e.; whichever time is the least amount available of the two).
The time being displayed is identified by the No Decompression Dive Time icon
(Fig. 7a), or the O2 Time icon (Fig. 8a). This unique feature has been granted
U.S. Patent No. 4,586,136.
No Decompression Dive Time Remaining
No Decompression Dive Time Remaining is the maximum amount of time that
you can stay at your present depth before entering a decompression situation.
It is calculated based on the amount of nitrogen absorbed by twelve hypotheti-
cal tissue compartments. The rates each of these compartments absorb and re-
lease nitrogen is mathematically modeled and compared against a maximum al-
lowable 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. 7b) along with the No Decompression Dive icon and
graphically as the Tissue Loading Bar Graph.
Fig. 7 - Dive Time Remaining
(No Deco Time is Less)
Fig. 8 - Dive Time Remaining
(O2 Accum Time is Less)
a
a
b

®
As you ascend from depth following a dive that has approached the no decom-
pression 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 Data
Plus 2 offers.
The no decompression algorithm is based upon Haldane’s theory using maxi-
mum allowable nitrogen levels developed by Merrill Spencer. Repetitive diving
control is based upon experiments designed and conducted by Dr. Ray Rogers
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,
calculations for the current depth will be controlled by oxygen. Oxygen Time
Remaining will then appear as the main numeric time display (Fig. 9a) as sig-
nified by the O
2
Time icon appearing to the right of the display. As oxygen ac-
cumulation continues to increase, the O2 bar graph will enter the yellow Cau-
tion Zone (described later).

ALPHA/NUMERIC DISPLAYS
Depth Displays
During a dive, CurrentDepth and Maximum Depth reached during that
dive are displayed from 0 to 330 feet (99.5 meters) in 1 foot (.5 meter) incre-
ments (Fig. 10 a & b).
During a Decompression Dive, the required Ceiling Stop Depth is displayed
from 60 to 10 feet (20 to 3 meters) in 10 foot (3 meter) increments.
Time Displays (Fig. 10 c & d) are shown in hour:minute format (i.e., 1:02
represents one hour and two minutes, not 102 minutes!). The colon that sepa-
rates hours and minutes blinks once per second when the display is indicating
real time such as elapsed Surface Time, Elapsed Dive Time, or Time of Day.
Dive Time Available, Dive Time Remaining, Decompression Stop Time, Total
Ascent Time required, Time to Fly, or Desaturation Time are calculated pro-
jections of time and use a solid (non-blinking) colon to indicate that they are
counting down, rather than up.
Depth and Time displays will be illustrated and described in more detail as ap-
plicable for each of the operating modes.

Ambient Temperatures from 0° to 99°F (-9 to 60°C) are displayed when the
Advance (Left) button is pressed while in the Surface Mode or in a dive mode.
BACKLIGHT FEATURE
In addition to using a high contrast LCD for easy readability in low light condi-
tions, the backlight features evenly illuminate the full display.
Smart Glo™, the surface mode backlight, senses the intensity of light that is
passing through the small ports located between the control buttons. If a low
level of light is sensed, the Smart Glo™ backlight will activate and illuminate
the display for button depression time plus 10 seconds when either button is
pressed.
Oceanglo
®
, the dive mode backlight, will illuminate the display for button de-
pression 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 bat-
tery life. The backlight will not activate during a 'low battery
condition', or when downloading data to a PC.

Data Plus 2
OPERATING TEMPERATURE
The Data Plus 2 will operate in almost any temperature diving environment in
the world between 0 and 140 °F (-9 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 Data Plus 2 will operate in this wide range of temperatures,
it is possible to damage the electronics if left exposed to direct sun-
light, or in a hot confined space (like a car trunk). After the dive, cover
the Data Plus 2 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 Data Plus 2
in water. The display should recover its normal appearance after a few min-
utes.
Damage from excess heat, or cold, is not covered by the Data Plus 2
two year limited warranty.

WARNINGS and SAFETY RECOMMENDATIONS
• Inspect your Data Plus 2 prior to every dive, checking for any signs of the entrance of mois-
ture, damage to the housing, or damage to the LCD display. If these or other signs of dam-
age 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 for-
mal 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 sig-
nificantly different and thus swapping dive computers could lead to inaccurate and poten-
tially 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
DataPlus2, due to the personal information it provides.

ACTIVATION
To activate the Data Plus 2, press the Select (Right) button once and release.
The Data Plus 2 will immediately enter Diagnostic Mode, displaying all “8’s”
(Fig. 11), followed by “dashes”, and a countdown from 9 to 0. While conduct-
ing diagnostics, the display is illuminated by the Smart Glo™ backlight as the
Data Plus 2 checks its display functions and battery voltage to ensure that ev-
erything is working correctly.
Upon activation, the Data Plus 2 will also check the ambient barometric pres-
sure, and calibrate its present depth as zero. At elevations of 2,000 ft. (610 m)
or higher, it will recalibrate itself to measure depth in feet of fresh water in-
stead of feet of sea water.
If no dive is made within 2 hours after initial activation, the Data Plus 2 will
automatically deactivate to conserve its battery power. Always check the
display before entering the water to ensure that it is activated.
SURFACE MODE
Surface Mode, identified by the Surface Time icon (Fig. 12a), immediately fol-
lows Diagnostic Mode after initial activation. Information displayed includes
the Dive Number '0' (no dive made yet) and Surface Time with flashing colon.

WARNINGS and SAFETY RECOMMENDATIONS
• Never activate the Data Plus 2 underwater. This may result in inaccurate depth and no-de-
compression time displays. If the unit is activated when deeper than 4 feet (1 meter) under-
water, or at elevations higher than 14,000 feet (4,267 meters), it will perform a diagnostic
check followed by immediate shutdown.
• During activation and diagnostics, if any display or function varies from the information
presented here, return the Data Plus 2 to your Oceanic Dealer for inspection.
• If a Low Battery condition is indicated following diagnostics, Oceanic strongly recommends
that you DO NOT dive until the battery is replaced.
