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

Beginning with firmware revision 2E, ATOM Watch/Dive Computers are place
in a Deep Sleep mo e prior to being shippe from the factory. The intent is to
exten storage life of the Battery for up to 7 years, before the unit is initially
place in service.
In this mo e, Date an Time are up ate as they normally woul be. However,
they are not isplaye . Upon waking the ATOM up, the correct Date an
Pacific T ime will be isplaye an it will be rea y to operate with full functions.
To wake the ATOM up from Deep Sleep mo e, simultaneously epress the
upper/right (S) an lower/left (A) buttons for 2 to 3 secon s until the isplay
comes full ON isplaying the MAIN TIME screen, then release them.
NOTE: Once the ATOM is brought out of the Deep Sleep
ode, it can only be placed back in it by the factory.

INTRODUCTION
Welcome to OCEANIC an thank you for choosing the ATOM 2.0 !
It is extremely important that you rea this Operating Manual in sequence an un erstan
it completely before attempting to use the ATOM 2.0 as a ive computer.
It is equally important that you rea the Oceanic Dive Computer Safety an Reference
Manual (Doc. No. 12-2262) provi e with your ATOM 2.0. It contains information that
you must become familiar with prior to iving with your ATOM 2.0.
Remember that technology is no substitute for common sense, an a ive computer only
provi es the person using it with ata, not the knowle ge to use it.
INTERACTIVE CONTROL CONSOLE
The Interactive Control Console consists of four Control Buttons that allow you to select
mo e options an access specific information. They are also use to link the
Transmitter(s), enter Settings, activate the Backlight, an acknowle ge the Au ible Alarm.
Throughout this manual they will be referre to as the M, S, L, an A buttons.
