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.
model is based upon the latest research and experiments in decompression theory.
The Pro Plus 2 dive computer
Still, using the Pro Plus 2, 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 Pro Plus 2 !
It is extremely important that you read this Operating Manual in sequence and understand
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.

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 Decompression (normal) zone, a yellow Caution zone (also No Decompression), and a red Decompression (danger) zone.
N2
DECO
While you cannot provide a guarantee against the occurrence
a
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 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).
O2
ATR
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 additional exposure is allowed for that dive and 24 hour period.
Variable Ascent Rate Indicator (VARI)
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 FT (18 M). Refer to the chart (Fig. 4) for segment
values.

Air Time Remaining Bar Graph (ATRBG)
N2
FEET
The Air Time Remaining Bar Graph (Fig. 5a) 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 reserve of breathing gas.
This calculation and display is based on your Breathing Gas
b
Consumption Rate that is continuously monitored by the Pro Plus
2, 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 and less,
based on your pre selected End Pressure Alarm Set Point (described later). The bar graph
is more precise as time decreases toward the red zone.
DIVE TIME REMAINING
The Pro Plus 2 constantly monitors three critical pieces of information; no decompression
status, oxygen accumulation, and breathing gas consumption rate. Refer to the Oceanic
Dive Computer Safety and Reference Manual which describes Dive Time Remaining which
is a display that indicates the time that is more critical for you at that particular moment
(i.e.; whichever time is the least amount available of the three).
Displayed will be either Time Remaining before reaching the No Decompression limit (Fig.
5b), or Time Remaining before reaching the limit for Oxygen Accumulation, or Time
Remaining before reaching the End Pressure Alarm set point.

 Press the button again to activate as desired.
a
N2
NOTE: Extensive use of the Backlight reduces
estimated Battery life. Also, the Backlight does not
operate during a Low Battery Condition or when
downloading data to a PC.
POWER SUPPLY
The Pro Plus 2 utilizes one (1) 3 volt, CR2 Lithium Battery that
should provide from 50 dive hours of operation, if you conduct 1 - one hour dive each time the unit is activated, to over
150 dive hours of operation, if you conduct 3 or more one
dives each time the unit is activated.
Battery Indicator
A Battery Indicator (Fig. 8a) provides an indication of Battery
O2
condition. The Battery Indicator will be displayed during
ATR
Fig. 8 - Battery Indicator
16
Surface Mode. It will not be displayed during Dive Mode(s).
Low Battery Condition
 Voltage level is checked upon activation and every 10
minutes during operation.
 When 75 % of the Rated Power has been consumed, only
the lower bar of the Indicator will be displayed and the
full icon will flash (Fig. 9) once per second as a warning
that the Battery is to be replaced prior to conducting any
further dives.
 Upon decreasing to a voltage level that will no longer
sustain proper operation, the Battery Indicator will flash 5
times followed by shutdown of the unit.
 If a Low Battery Condition exists when the unit is manually
activated (by pressing the button), the graphic bAT and
N2
the Battery Indicator will appear flashing for 5 seconds
followed by shutdown of the unit.
 If the button is not pressed to activate the unit prior to a
dive (e.g., the unit activated automatically by immersion in
water), and a Low Battery Condition exists, the Battery
Indicator will appear flashing as a warning upon descent
past 4 feet (1.2 meters). No other information will be
displayed and the unit will not enter Dive Mode.

 If the unit did not display a Low Battery Condition prior to
entering the Dive Mode, and a Low Battery Condition
occurs during the dive, there will be sufficient Battery
power to maintain unit operation for the remainder of that
dive. The Battery Indicator will appear after the dive upon
entry into Surface Mode.
 When the Battery is removed, settings and calculations for
repetitive dives will be retained, if a new battery can be
inserted within 8 seconds. Otherwise the calculations will
reset to zero and settings must be reset.
FO2 MODE
After Activation, the Pro Plus 2 will operate as an Air comN2
puter without displaying information associated with oxygen
calculations, unless it is set for a percentage of oxygen (FO2)
other than Air (a numerical value between 21 and 50 %).
When set with an FO2 value of 'Air' (Fig. 10), the Pro Plus
2 will perform calculations the same as if FO2 were set for
21% oxygen, internally accounting for oxygen loading for any
subsequent Nitrox dives. However, oxygen related displays,
O2
warnings, and the O2 Bar Graph will not appear on the
ATR
Fig. 10 - FO2 set for AIR

display for that dive, or subsequent dives, unless FO2 is set
for a numerical value (21 - 50).
Once a dive is made with the unit set as a Nitrox Computer
N2
(FO2 set for a numerical value), it cannot be programmed to
operate as an Air Computer until 24 hours after the last dive.
'Air' will not be displayed as an option in the FO2 Mode.
However, you can set FO2 for 21% for use with Air.
MAX
When FO2 is set at a value of 21% (Fig. 11), the unit will
remain set at 21% for subsequent nitrox dives until FO2 is set
to a higher value, or until it automatically turns off and is
O2
reactivated.

FO2 50% Default
Fig. 11 - FO2 set for 21%
If the Default function is set to ON (Fig. 12) and FO2
is set to a value 'greater than 21%', the FO2 set point value
will automatically revert to 50% 10 minutes after that dive.
N2
The Maximum Depth that can be achieved with a PO2 of
1.60 ATA will also be displayed.
 FO2 must therefore be reset for each repetitive nitrox dive,
or the value will automatically 'default' to 50(%) and the
dives will be calculated based on 50% O2 (50% nitrogen)
for oxygen calculations and 21% O2 (79% nitrogen) for
nitrogen calculations.

point will default to AIR regardless if the 50%
Default is set ON or OFF. Always set, or verify, the
FO2 set point prior to each nitrox dive.

CONTROL OF DISPLAYS
During No Decompression conditions, various displays of information (up to 4) are available. Each provides Depth, Dive Time Remaining, and additional information. The intent
of this feature is to provide the diver control of how much information is on the display at
any given time during the dive. The diver can change from one display to another as often
as desired by pressing the Left (Advance) button, otherwise it does not change. An exception to this is during a 3 minute no decompression dive Safety Stop (described on page
53).

During conditions in which Cautionary type information is displayed (e.g., No Decompression Safety Stop, Decompression, High PO2, etc.), there is a Main Display of important
information relevant to the specific condition. The diver can access another display, but it
will automatically revert to the Main Display after 3 seconds.
To activate the Backlight during a dive, press the Right (Select) button.

WARNING: Prior to diving with the Pro Plus 2, you
must also read and understand the Oceanic Dive
Computer Safety and Reference Manual which
provides Important Warnings and Safety Recommendations as well as general product information.
GENERAL
83
CARE AND CLEANING
Protect your Pro Plus 2 from shock, excessive temperatures,
chemical attack, and tampering. Protect the lens against
scratches with a transparent Instrument Lens Protector. Small
scratches will naturally disappear underwater.
 Soak and rinse the Pro Plus 2 in fresh water at the end of
each day of diving, and check to ensure that the areas
around the Low Pressure (Depth) Sensor (Fig. 95a),
Download Interface Port (Fig. 95b), and Buttons are free
of debris or obstructions.
 To dissolve salt crystals, use lukewarm water or a slightly
acidic white vinegar/water bath. After removal from the
bath, place the unit under gently running water and towel
dry before storing.
a
 Transport your unit cool, dry, and protected.
INSPECTIONS AND SERVICE
Your Pro Plus 2 should be inspected annually by an
Authorized Oceanic Dealer who will perform a factory
X

X
X
prescribed function check and inspection for damage or
wear. To keep the 2 year limited warranty in effect, this
inspection must be completed one year after purchase (+/- 30
days). Oceanic recommends that you continue to have this
inspection performed every year to ensure it is working
properly. The costs of annual inspections are not covered
b

under the terms of the 2 year limited warranty.
To Obtain Service:
Take your Pro Plus 2 to an Authorized Oceanic Dealer or
send it to the nearest Oceanic Regional Distributor Facility.
To return your Pro Plus 2 to Oceanic:
 Record all dive data in the Log and/or download the data
in memory. All data will be erased when it receives
factory service.
 Package it using a protective cushioning material.
 Include a legible note stating specific reason for return,
your name, address, daytime phone number, serial
number, and a copy of your original sales receipt and
Warranty Registration Card.

NOTE: The procedures that follow must be closely adhered to. Damage due
to improper Battery replacement is not covered by the unit's 2 year warranty.
BATTERY REPLACEMENT
The Battery Compartment should only be opened in a dry and clean environment with
extreme care taken to prevent the entrance of moisture or dust.
As an additional precautionary measure to prevent formation of moisture in the Battery
Compartment, it is recommended that the Battery be changed in an environment equivalent
to the local outdoor temperature and humidity (e.g., do not change the Battery in an air
conditioned environment then take it outside during a hot sunny day).
Inspect the Buttons, Lens, and Housing to ensure they are not cracked or damaged. If
there is any sign of moisture in the module, DO NOT use the Pro Plus 2 until it receives
proper service by an Authorized Oceanic Dealer, or the Oceanic factory.
Hot Swap
If the new Battery can be inserted within 8 seconds after the old one is removed (Hot
Swap), settings and nitrogen and oxygen calculations for repetitive dives will be retained.
86
Battery Removal
Examine the Case Back to locate the Battery Hatch (Fig. 96a):
 Remove the 4 screws that secure the Battery Hatch to the
Housing by turning counter clockwise.
 Lift the Hatch up and away from the Housing.
 Lift the Battery, positive (+) end first, out of the Battery
Compartment.
 Remove the Battery Hatch O-ring and inspect it for any
signs of deterioration or deformity. DO NOT use tools to
remove the O-ring.
 O-ring replacement is highly recommended to ensure
proper sealing.
 Closely examine the sealing surfaces of the Battery Hatch
and Housing for any signs of damage that might prevent
proper sealing. If found, return the Pro Plus 2 to an Authorized Oceanic Dealer, and DO NOT attempt to use it until
it has received factory service.
 Closely examine the inside of the Battery Compartment for
any signs of corrosion indicating entrance of moisture into
X
X
X
X
the unit.
 If corrosion is found, return the Pro Plus 2 to an Authorized
Oceanic Dealer, and DO NOT attempt to use it until it has
received factory service.

Moisture in the Battery Compartment
 If moisture is found, it is best to have the unit inspected
and cleaned by an Authorized Oceanic Dealer.
 If it is necessary to clean the Battery Compartment, flush
the it and all components with a solution of 50% white
vinegar and 50% fresh water. Rinse with fresh water, and
allow to dry overnight, or blow dry with a hair dryer (set
+
at 'no heat').
 Closely check all of the sealing surfaces for any signs of
damage that might impair proper sealing.
 Inspect the Buttons, Lens, and Housing to ensure they are
a
not cracked or damaged.
Fig. 97 - O-ring Installation
Battery Installation
 Replace the Hatch O-ring with a new one. This O-ring
must be a genuine Oceanic part that can be purchased
from an Authorized Oceanic Dealer.
Use of any other O-
ring will void the warranty.
 Lightly lubricate the new Hatch O-ring with silicone
grease and place it on the beveled outer edge of the
Battery Compartment (Fig. 97a). Ensure that it is evenly
+
seated.
a
 Place a new 3 volt, CR2, .75 AHr, Lithium Battery
(Duracell model DL-CR2 or equivalent) negative end first
into the Battery Compartment with the negative end
Fig. 98 - Battery Orientation
88
toward the spring (Fig. 98a).
Battery Hatch Installation
 Ensure that the Battery is properly oriented and the Hatch
O-ring is evenly seated.
 Carefully place the Battery Hatch into position so that it
seats on top of the O-ring, and while holding it in place,
secure it with the 4 screws by turning them clockwise. DO
NOT attempt to use any other screws.
 Carefully tighten the screws by alternately turning them
each one turn at a time (Fig. 99). Turn the upper left one
(a), then the lower right (b), then the lower left (c), then the
upper right (d).
 Repeat the sequence until all of the screws are evenly
secure. The outer surface of the Battery Hatch should be
flush with the outer surface of the Housing. DO NOT
overtighten.
Inspection
 Activate the unit and watch carefully as it performs a full
diagnostic and battery check, and enters Surface Mode.
Observe the LCD display to ensure it is consistently clear
