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 XR1 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 XR1
dive computer model is based upon the latest research and experiments in decompression theory. Still, using
the XR1, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding de-
compression 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.
