INTRODUCTION Welcome to Oceanic and thank you for choosing the VT Pro ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the VT Pro. It is equally important that you read the Oceanic Dive Computer Safety and Reference Manual (Doc. No. 12-2262) provided with your VT Pro. It contains information that you must become familiar with prior to diving with your VT Pro.
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.
Deeper than 60 feet (18 m) Segments Ascent Rate = Displayed FPM MPM 0 0-20 0-6 1 21-30 6.5-9 2 31-40 9.5-12 3 41-50 12.5-15 4 51-60 15.5-18 5 >60 >18 60 feet (18 m) & Shallower Segments Ascent Rate = Displayed FPM MPM 0 0-10 0-3 1 11-15 3.5-4.5 2 16-20 5-6 3 21-25 6.5-7.5 4 26-30 8-9 5 >30 >9 a 60 50 40 30 20 10 5 b O2 0 ATR Fig. 3 - VARI & ATRBG 12 Variable Ascent Rate Indicator (VARI) The Variable Ascent Rate Indicator (Fig. 3a) provides a visual representation of ascent speed (i.e.
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 VT Pro constantly monitors three critical pieces of information; no decompression status, oxygen accumulation, and breathing gas consumption rate.
Depth Displays During a dive, the Current Depth display (Fig. 6a), indicates Depths from 0 to 399 feet (120 meters) in 1 foot (.1 meter) increments. By pressing the Front (Advance) button, the Maximum Depth reached during that dive will be displayed (Fig. 6b). During a Decompression Dive, the required Ceiling Stop Depth is displayed in the Max Depth position. Maximum Depth can be viewed by pressing the Front (Advance) button. Time and Date Displays Time displays are shown in hour:minute format (i.e.
Temperature Display Ambient Temperature is displayed in Surface Mode and Log Mode, and can be viewed on an Alternate Display when the Front (Advance) button is pressed while in a dive mode (Fig. 7a). If the Temperature exceeds a value of '99', 2 dashes ( - - ) will be displayed until temperature decreases to '99'. NOTE: Each display represents unique pieces of information.
Situations that will sound the Alarm, if it is turned ON (a user setting), include • Entry into Decompression Mode. • Air Time Remaining Bar Graph Alarm (a user setting). • Air Time Remaining = 5 minutes, then 0 minutes. • Turn Pressure Alarm (a user setting). • End Pressure Alarm (a user setting). • PO2 => than the Max PO2 Alarm (a user setting), or => 1.60 ATA. • Descent deeper than the Max Depth Alarm (a user setting). • Tissue Loading Bar Graph Alarm (a user setting).
During the following situations, the 10 second continuous tone will be followed by a 5 second steady beep that will not turn off when acknowledged • Ascending above a required Decompression Ceiling Stop Depth for more than 5 minutes (referred to as a Delayed Violation). • Decompression requires a Ceiling Stop Depth of 70 feet/21 meters or deeper. • Being on the Surface for 5 minutes after a Conditional Violation (Permanent Violation).
Low Battery Condition Voltage level is checked upon activation and every 10 minutes during operation. When a Low Battery Condition occurs (either the Display Module or Transmitter), the Battery icon appears on the display flashing during Surface Mode (Fig. 8) and Fly/Desat Mode (after 2 hours on the surface following a dive). PSI O2 ATR Fig. 8 - Low Battery (Surface Mode) O2 ATR Fig. 9A - Battery Indicator Display Module O2 ATR Fig.
FO2 MODE After Activation, the VT Pro will operate as an Air computer 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 VT Pro will perform calculations the same as if FO2 were set for 21% oxygen, internally accounting for oxygen loading for any subsequent Nitrox dives.
FO2 50% Default O2 ATR Fig. 12 - FO2 Default ON 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. The Maximum Depth that can be achieved with a PO2 of 1.60 ATA will also be displayed.
WARNING: Prior to diving with the VT Pro, 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.
PRESSURE TRANSMITTER Before you dive with the VT Pro, you will need to become familiar with the interactive features and select desired settings. The Transmitter must be installed into the High Pressure port of your Regulator First Stage, facing to one side (Fig. 14). Oceanic strongly recommends that installation be performed by an Authorized Oceanic Dealer at the time of purchase. Instructions are provided on Page 92.
To Activate the VT Pro • position the Display Module within 3 feet (1 meter) of and parallel to the Transmitter (Fig. 15), holding it in this location during activation. • press and release the Front (Advance) Button. • Upon manual activation, the unit will enter Diagnostic Mode (Fig. 16), displaying all segments of the LCD as 8's, followed by dashes (- -), then a countdown from 9 to 0.

Poor Reception Distance (greater than 3 feet/1 meter) Poor Reception Area Best Reception Area Poor Reception Area Poor Reception Area Fig.
POSITIONING OF THE DISPLAY MODULE The Transmitter emits a low frequency signal that radiates outward in a semicircular pattern that is parallel to the length dimension of the Transmitter. A coiled antenna inside the Display Module receives the signal when it is positioned within a zone parallel to or at a 45 degree angle to the Transmitter as shown on page 46 Fig. 50.
An interruption of the Link may also occur while the Display Module is in an area within 3 to 4 feet (1 meter) of a running Dive Propulsion Vehicle. The Link will be restored within 4 seconds after the Vehicle is shut off or the Display Module is moved out of that area. When using a Strobe, a temporary interruption may occur shortly after the Strobe flashes. The Link will be restored within 4 seconds.

NOTE: The VT Pro will store oxygen accumulation calculations for up to 10 dives conducted during a 24 hour period. If the maximum limit for oxygen loading has been exceeded for that day (24 hour period), all of the segments of the O2 Bar Graph will be displayed flashing . Depth/Time values will not appear until the O2 Bar Graph recedes into the green (normal) zone (i.e., your daily oxygen dosage decreases an amount equivalent to the amount accumulated during the latest dive completed).
VARIABLE ASCENT RATE INDICATOR The Variable Ascent Rate Indicator (VARI) shows how fast you are ascending. When you exceed the maximum recommended Ascent Rate for the depth you are at, it will enter the red (Too Fast) zone and you will be alerted all segments of the Bar Graph flashing (Fig. 55), an Audible alarm, and the red LED Warning Indicator, unless set OFF. The warnings will stop when your Ascent Rate is slowed. FEET 20 10 5 PSI 0 O2 ATR Fig.
CONTROL OF DISPLAYS During No Decompression conditions, up to 4 Main Displays of information are available. Each provides Depth, Dive Time Remaining, Mode icon (Fig. 57) and additional information. The intent of this feature is to provide you with control of how much information is displayed at any given time during the dive. You can change from one Main Display to another as often as desired by pressing the Front (Advance) button. The Display will not automatically revert to a default display.
NO DECOMPRESSION DIVE MODE The VT Pro will enter the No Decompression Dive Mode when you descend deeper than 4 feet (1.2 meters). FEET No Deco Dive Mode - Main Display #1 (Fig. 58) Information includes Current Depth, Dive Time Remaining and Mode icon, Tank Pressure, and the applicable bar graphs. 20 10 5 PSI 0 O2 • Press and release the Front (Advance) button to view Display #2.

No Decompression Dive Mode - Secondary Display (Fig. 62) Information includes Current Depth, Air Time Remaining (and Mode icon), and applicable bar graphs.
The Safety Stop will be displayed until the countdown times out, or you descend below 30 feet (10 meters), or you surface. There is no Penalty if you surface prior to completing the Safety Stop. DECOMPRESSION DIVE MODE The VT Pro is designed to help you by providing a representation of how close you are to entering Decompression. Decompression Dive Mode (Fig. 64) activates when theoretical No Decompression time/depth limits are exceeded.
a b FEET 20 10 5 PSI 0 O2 c ATR Fig. 65 - Deco #1 Main Default Managing Decompression Stops To fulfill your decompression obligation, you should make a safe controlled ascent to a depth slightly deeper than (Fig. 65a), or equal to, the Required Ceiling Stop Depth indicated (Fig. 65b) and decompress for the Stop Time indicated (Fig. 65c). The amount of decompression credit time that you receive is dependent on depth, with slightly less credit given the deeper you are.
Deco Dive Mode - Display #3 Alternate (Fig. 67) Information includes - Current Depth, Temperature, Time of Day and icon, Total Ascent Time and Mode icon, Tank Pressure, both Arrows and the Deco Bar, and the bar graphs. Deco Dive Mode - Display #4 Alternate (Fig. 68) Information includes - Current Depth, the current value of PO2 (if a nitrox dive) and PO2 graphic, Total Ascent Time and Mode icon, Tank Pressure, both Arrows and the Deco Bar, and applicable bar graphs.
Unless set OFF, the Audible Alarm will emit a continuous tone and the red LED Warning Light will flash for 10 seconds, or until acknowledged by pressing the Front (Advance) button. If you descend below the required decompression ceiling before 5 minutes have elapsed, the VT Pro will continue to function in Decompression Dive Mode. In this case, no offgassing credit will be given, and for each minute above the ceiling 11/2 minutes of Penalty Time will be added to Required Stop Time.
Delayed Violation Mode #2 (Fig. 71) The VT Pro cannot calculate decompression times for Stop Depths much greater than 60 feet (18 meters) and offers no indication of how much time spent underwater would result in the need for a greater Stop Depth. If the Decompression obligation requires a Ceiling Stop Depth between 60 feet (18 meters) and 70 feet (21 meters), the Tissue Loading Bar Graph will flash. Total Ascent Time will still be displayed. FEET 30 20 10 5 PSI 0 O2 ATR Fig.
Upon ascending above 330 feet (99.9 meters), the Current Depth display will be restored, however Max Depth will only display 3 dashes for the remainder of that dive. The Log for that dive will display 3 dashes as the Max Depth achieved. Immediate Violation Mode and Gauge Mode If a ceiling much greater than 60 feet (18 meters) is required, an Immediate Violation Mode will be entered. This situation would be preceded by entering Delayed Violation Mode #2.
Surface Gauge Mode displays the Dive Number, Temperature, Time of Day, Surface Interval, and Tank Pressure (Fig. 74). It does not provide access to the FO2, PDPS, or Time to Fly and Desaturate features. The countdown timer that appears when you try to access Time to Fly does not represent Time to Fly. It is only provided to inform you of the time remaining before normal VT Pro operation can resume with full features and functions. O2 O2 PSI ATR Fig.
If PO2 continues to increase, the value displayed will increase toward a maximum value of 5.00 ATA in increments of .01 ATA. When it reaches a value of 1.60 ATA, or the PO2 Alarm set point (a user setting), the Audible Alarm will sound (unless set OFF) and the current PO2 value, PO2 symbol, O2 segment of the O2 Bar Graph, and UP Arrow will flash as a warning (Fig. 76) until PO2 decreases. • Press the Front (Advance) button to view the Alternate Displays.
If the theoretical amount of oxygen accumulated equals, or exceeds, the limit for a single exposure, or the exposure limit for a 24 hour period, Oxygen Dive Time Remaining becomes zero (0:00) and the O2 Bar Graph will enter the red O2 (Danger) Zone (Fig. 77). The red LED warning will flash, the Audible Alarm will sound (unless set OFF), and the UP Arrow and the full O2 Bar Graph will flash as a warning until the level of oxygen decreases below the limit.

WARNING: Prior to diving with the VT Pro, 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.
CARE AND CLEANING Protect your VT Pro 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 Display Module 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. 105a), Download Interface Data Port (Fig. 105b), and Buttons are free of debris or obstructions.
To Obtain Service: Take your VT Pro to an Authorized Oceanic Dealer or send it to the nearest Oceanic Regional Distributor Facility (page 99). To return your VT Pro to Oceanic: • Record all dive data in the Log and/or download the data in memory. All data will be erased during factory service. • Package it using a protective cushioning material.
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. When replacing the Battery in the Display Module, it is recommended that you also replace the Battery in the Transmitter, and vice-versa. BATTERY REPLACEMENT The Battery Compartment(s) should only be opened in a dry and clean environment with extreme care taken to prevent the entrance of moisture or dust.
Display Module Battery Hatch Removal • Locate the Battery Compartment on the back of the module. • While applying steady inward pressure on the clear Battery Hatch, rotate the Hatch Ring clockwise 10 degrees by pressing on the upper/right arm of the Ring with a small blade screwdriver (Fig. 106A). NOTE: If available, an adjustable face spanner tool or a pair of pointed pliers can be used instead of the screwdriver by inserting the tips of the tool in the small holes in the Ring (Fig. 106B). Fig.
Transmitter Battery Removal Locate the Battery Hatch on the End of the Housing: • Apply a coin (not a screwdriver) to the recessed slot of the Battery Hatch and turn the Hatch out of the Housing by turning it counter clockwise. • Remove the Battery from the Battery Compartment and discard according to local regulations governing disposal of batteries. Inspection • Closely check all of the sealing surfaces for any signs of damage that might impair proper sealing.
Inspection (continued) • Closely examine the inside of the Battery Compartment(s) for any signs of corrosion indicating entrance of moisture into the unit. • If corrosion is found, return the VT Pro to an Authorized Oceanic Dealer, and DO NOT attempt to use it until it has received factory service. • If moisture is found, it is best to have the unit inspected and cleaned by an Authorized Oceanic Dealer.
Fig. 109 - Tightening Ring Fig. 110 - Transmitter O-ring Installation 90 Display Module Battery Installation (continued) • Carefully place the clear Battery Hatch (with O-ring) into position on the rim of the Battery Compartment, then press it evenly and completely down into place with your same thumb. • Maintain the Battery Hatch securely in place and, using your other hand, slide the Hatch Ring down off your thumb and into position around the Battery Compartment.
Transmitter Battery Installation (continued) • Place a new 3 volt, CR2, Lithium Battery (Duracell model DLCR2 or equivalent) positive (+) side down into the Battery Compartment with the negative end facing up/out (Fig. 111). • Ensure that the Battery is properly oriented and the Hatch Oring is evenly seated around the Battery Hatch. • Carefully place the Battery Hatch with Spring into the Housing and turn clockwise slowly by hand to ensure proper threading. Apply a coin and tighten until secure.
DI RESP O VER TRANSMITTER INSTALLATION To install the Transmitter on your Regulator First Stage: • Remove the existing Pressure Gauge and High Pressure Hose, or the High Pressure Port Plug from the Port marked HP using the proper size Hex Key. • Lightly lubricate the O-ring and Threads of the Transmitter fitting with a halocarbon based lubricant such as Christo-Lube MCG111 (provided in Oceanic Battery Kits).
