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), and 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 ATMOS 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 ATMOS
2 dive computer model is based upon the latest research and experiments in decompression theory. Still, using
the ATMOS 2, just as using the U.S. Navy (or other) No Decom ression Tables, is no guarantee of avoid-
ing decom ression sickness, i.e. the bends. Every divers 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.

FEATURES and DISPLAYS
WARNING: Prior o diving wi h he A mos 2, you mus also read and

Recommenda ions as well as general produc informa ion.

WELCOME TO AERIS !
AND
THANK YOU FOR CHOOSING THE ATMOS 2 !
Your ATMOS 2 presents the information that you need before, during, and after your air (or
nitrox) dives using a combination of easy to read disp ays and identification icons. It can a so be
set to operate simp y as a digita depth gauge/timer. This instructiona guide is intended to he p
you become fami iar with the functions and features avai ab e and show you examp es of disp ays
that you cou d expect to see in the various operationa modes. Re ax and read through the com-
p ete operating manua .
Remember that the ru es you earned in your basic scuba certification course(s) sti app y to the
diving you wi do whi e using a dive computer - some wi become even more important. Tech-
no ogy is no substitute for common sense, and a dive computer on y provides the person using it
with data, not the know edge to use it.
Since the ATMOS 2 can be used when diving with either Air or Nitrox, the term Breathing Gas is
used in this manua .
Breathing Gas is the gaseous mixture breathed during a dive.
Air is a breathing gas that contains approximate y 21% oxygen and 79% nitrogen (nature's
common nitrogen-oxygen mixture).
Nitrox is a nitrogen-oxygen breathing gas that contains a higher fraction of oxygen (22 to 50%)
than air.

CONTROL BUTTONS
The two Contro Buttons a ow you to se ect disp ay options, access specific information when
you want to see it, and activate the Back ight.
The Front button is named Advance (Fig. 1a) and the Side button Select (Fig. 1b).
BAR GRAPHS
Ni rogen Bar Graph
The Nitrogen Bar Graph (Fig. 1c) represents tissue oading of nitrogen, showing your re ative No
Decompression or Decompression status. As your Depth and E apsed Dive Time increase, seg-
ments wi add to the Graph, and as you Ascend to sha ower depths, the Bar Graph wi begin to
recede, indicating that additiona No Decompression Time is a owed for mu ti eve diving.
The Nitrogen Bar Graph monitors 12 different nitrogen compart-
ments simu taneous y and disp ays the one that is in contro of your
dive. It is divided into a green No Decompression (norma ) zone, a
ye ow Caution zone (a so No Decompression), and a red Decom-
pression (danger) zone.
Whi e you cannot provide a guarantee against the occurrence of de-
compression sickness, you may choose your own persona zone of
caution based upon age, physique, excessive weight, etc., to reduce
the statistica risk.

Oxygen (O2) Accumula ion Bar Graph
The O2 Bar Graph (Fig. 2a) represents Oxygen Loading, your re a-
tive oxygen to erance dosage (OTU), showing the maximum of ei-
ther per dive accumu ated Oxygen, or 24 hour period accumu ated
Oxygen. As your accumu ation increases during the dive, seg-
ments wi add to the Bar Graph, and as oading decreases, it wi
begin to recede, indicating that additiona exposure is a owed.
NOTE: Displays associa ed wi h Oxygen and he
O2 Bar Graph will only appear if FO2 has been se
a a value o her han 'Air' (e.g., a numerical value).
Variable Ascen Ra e Indica or
The Variab e Ascent Rate Indicator (Fig. 2b) provides a visua rep-
resentation of Ascent Speed (i.e., an ascent speedometer). Green
is a 'norma ' rate, ye ow a 'caution' rate, and red is 'Too Fast'. The
segments of the Variab e Ascent Rate Indicator represent 2 sets of
speeds which change at a reference depth of 60 feet (18 meters).
Refer to the chart for segment va ues.
WARNING: A dep hs grea er han 60 fee (18
me ers), Ascen Ra es should no exceed 60 fee
per minu e (18 mpm). A dep hs of 60 fee (18
me ers) and shallower, Ascen Ra es should no
exceed 30 fee per minu e (9 me ers per minu e).
