PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Air Time Remaining (U.S. Patent no. 4,586,136 and 6,543,444) and Data Sensing and Processing Device (U.S. Patent
no. 4,882,678). Set TLBG Alarm and other patents pending. User Setable Display (U.S. Patent no. 5,845,235) is
owned by Suunto Oy (Finland).
DECOMPRESSION MODEL
The programs within the VT3 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 VT3 dive computer model is
based upon the latest research and experiments in decompression theory.
Still, using the VT3, just as using the
U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression sick-
ness, 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.
8
WARNING: If your VT3 stops working for any reason while oper-
ating as a Dive Computer, it is important that you have anticipated
this possibility and are prepared for it. This is an important rea-
son for not pushing the no decompression and oxygen exposure
limits, and a critical reason to avoid entering decompression. If
you dive in situations where your trip would be ruined or your
safety would be jeopardized by losing the use of your VT3, a
backup instrument system is highly recommended.
FCC ID: MH8A
FCC COMPLIANCE:
This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two 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 connected.
 Consult the dealer or an experienced radio/TV technician.
Warning: Changes or modifications to this unit not expressly approved by Oceanic/2002 Design could
void the user's authority to operate the equipment.

WARNING: Prior to diving with the VT3, you
must also read and understand the Oceanic
Dive Computer Safety and Reference Manual,
Doc. No. 12-2262, which provides Important
Warnings and Safety Recommendations as
well as general product information.

INTRODUCTION
Welcome to OCEANIC and thank you for choosing the VT3 !
It is extremely important that you read this Operating Manual in sequence and understand
it completely before attempting to use the VT3 as a dive computer.
It is equally important that you read the Oceanic Dive Computer Safety and Reference
Manual (Doc. No. 12-2262) provided with your VT3. It contains information that you must
become familiar with prior to diving with your VT3.
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.
INTERACTIVE CONTROL CONSOLE
The Interactive Control Console consists of 3 Control Buttons that allow you to select mode
options and access specific information. They are also used to link the Transmitter(s), enter
Settings, activate the Backlight, and acknowledge the Audible Alarm.
Throughout this manual they will be referred to as the M, S, and A buttons.
