PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the follo ing 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 o ned by Suunto Oy (Finland).
DECOMPRESSION MODEL
The programs ithin the XR2 simulate the absorption of nitrogen into the body by using a mathematical
model. This model is merely a ay to apply a limited set of data to a large range of experiences. The XR2
dive computer model is based upon the latest research and experiments in decompression theory. Still, using
the XR2, just as using the U.S. Navy (or other) No Decompression Ta les, is no guarantee of avoiding de-
compression sickness, i.e. the ends. Every divers physiology is different, and can even vary from day to
day. No machine can predict ho your body ill react to a particular dive profile.

WARNING: Prior o diving wi h he XR2, you mus also read and

Recommenda ions as well as general produc informa ion.

WELCOME TO AERIS !
AND
THANK YOU FOR CHOOSING THE XR2 !
Your XR2 presents the information that you need before, during, and after your air (or nitrox)
dives using a combination of easy to read displays and identification icons. It can also be set to
operate simply as a digital depth gauge timer. This instructional guide is intended to help you be-
come familiar with the functions and features available and show you examples of displays that
you could expect to see in the various operational modes. Relax and read through the complete
owner's guide.
Remember that the rules you learned in your basic scuba certification course(s) still apply to the
diving you will do while using a dive computer - some will become even more important. Tech-
nology is no substitute for common sense, and a dive computer only provides the person using it
with data, not the knowledge to use it.
Since the XR2 can be used when diving with either Air or Nitrox, the term Breathing Gas is used
in this manual.
Breathing Gas is the gaseous mixture breathed during a dive.
Air is a breathing gas that contains approximately 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 Control Buttons allow you to select display options, access specific information when
you want to see it, and activate the Backlight.
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 loading of nitrogen, showing your relative No
Decompression or Decompression status. As your Depth and Elapsed Dive Time increase, seg-
ments will add to the Graph, and as you Ascend to shallower depths, the Bar Graph will begin to
recede, indicating that additional No Decompression Time is allowed for multilevel diving.
The Nitrogen Bar Graph monitors 12 different nitrogen compart-
ments simultaneously and displays the one that is in control of your
dive. It is divided into a gray No Decompression (normal) zone, a
yellow Caution zone (also No Decompression), and a red Decom-
pression (danger) zone.
While you cannot provide a guarantee against the occurrence of de-
compression sickness, you may choose your own personal zone of
caution based upon age, physique, excessive weight, etc., to reduce
the statistical risk.

Oxygen (O2) Accumula ion Bar Graph
The O2 Bar Graph (Fig. 2a) represents Oxygen Loading, your rela-
tive oxygen tolerance dosage (OTU), showing the maximum of ei-
ther per dive accumulated Oxygen, or 24 hour period accumulated
Oxygen. As your accumulation increases during the dive, seg-
ments will add to the Bar Graph, and as loading decreases, it will
begin to recede, indicating that additional exposure is allowed.
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 Variable Ascent Rate Indicator (Fig. 2b) provides a visual rep-
resentation of Ascent Speed (i.e., an ascent speedometer). Gray is
a 'normal' rate, yellow a 'caution' rate, and red is 'Too Fast'. The
segments of the Variable 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 values.
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).
