WARNINGS and SAFETY RECOMMENDATIONS
• The Data Plus 2 is intended for use by recreational divers who have successfully completed a
nationally recognized course in scuba diving, and diving with enriched nitrogen-oxygen
(nitrox) mixtures.
• It is intended only for no decompression diving, NOT intentional decompression diving.
• It must not be used by untrained persons who may not have knowledge of the potential risks
and hazards of scuba diving, and diving with enriched nitrogen-oxygen (nitrox) mixtures.
• You must obtain scuba certification, and certfication in diving with enriched nitrogen-oxy-
gen (nitrox) mixtures before using the Data Plus 2 if you have not already done so.
• It is NOT for use by military and commercial divers.
• It should NOT be utilized for any competitive, or repetitive square wave or decompression
diving, as it is intended solely for recreational use and no decompression multilevel diving.
• As with all underwater life support equipment, improper use or misuse of this product can
cause serious injury or death.
• Never participate in sharing or swapping of a dive computer.
• Conduct your dives in such a manner so as to insure that you continuously check the
computer's proper function.
• Read and understand this owner’s guide completely before diving with the Data Plus 2.
• If you do not fully understand how to use this dive computer, or if you have any questions,
you should seek instruction in its use from your Authorized Oceanic Dealer before you uti-
lize this product.

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.
