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 VT Pro 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 VT Pro dive computer model
is based upon the latest research and experiments in decompression theory. Still, using the VT Pro, 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.

FCC ID: MH8A
FCC Compliance:
This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following 2
conditions: 1.) this equipment may not cause harmful interference, and 2.) this equipment must accept
any interference received, including interference that may cause undesired operation.
FCC Interference Statement:
This equipment has been tested and found to comply with the limits for an Intentional Radiator, a Class
B Digital Device, pursuant to Part 15 of FCC Rules, Title 47 of the Code of Federal Regulations. These
rules are designed to provide reasonable protection against harmful interference in a commercial or
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful interference to radio
communications.
There is no guarantee that interference will not occur in a particular installation. If this equipment does
cause interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to which the receiver is con-
nected.
• Consult the dealer or an experienced radio/TV technician.
Warning: Changes or modifications to this unit not expressly ap-
proved by Oceanic/2002 Design could void the user's authority to
operate the equipment.

FEATURES and DISPLAYS
WARNING: Prior to diving with the T Pro, you
must also read and understand the Oceanic Dive
Computer Safety and Reference Manual which
provides Important Warnings and Safety Recom-
mendations as well as general product information.

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.
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 link
the Transmitter, enter Settings, activate the Backlight, and ac-
knowledge the Audible Alarm.
The Front button is referred to as Advance (Fig. 1a) and the
Side button as Select (Fig. 1b).
