1. WELCOME TO THE WORLD OF SUUNTO DIVE COMPUTERS
Suunto D9tx wristop dive computer is designed to help you get the most out of your
diving.
Suunto D9tx is the world’s first wristop sized dive computer to integrate a tilt-com-
pensated 3D digital compass, wireless tank pressure reception, and trimix functions.It
simplifies your diving experience because all the information you need relating to
depth, time, optional tank pressure, decompression status, and direction is now
available on one easy-to-read screen.
The Suunto D9tx User's Guide contains vitally important information which enables
you to become familiar with your Suunto wristop dive computer. To understand the
use, displays, and limitations of the instrument before using it, please read this user's
guide carefully, and save it for further reference. Note also that a glossary is included
at the back of the user's guide to help you understand dive-specific terminology.

2. WARNINGS, CAUTIONS, AND NOTES
Throughout this user's guide, important safety icons are displayed. Three classifications
are used to separate these icons by their order of importance:
WARNING is used in connection with a procedure or situation that may
result in serious injury or death
CAUTION is used in connection with a procedure or situation that will
result in damage to the device
NOTE is used to emphasize important information
Before you go on to read the user's guide itself, it is extremely important that you read
the following warnings. These warnings are intended to maximize your safety while
using Suunto D9tx and must not be ignored.
WARNING YOU MUST READ the leaflet and user guide for your dive
computer. Failure to do so may lead to improper use, serious
injury or death.
WARNING ALLERGIC REACTIONS OR SKIN IRRITATIONS MAY OC-
CUR WHEN PRODUCT IS IN CONTACT WITH SKIN, EVEN
THOUGH OUR PRODUCTS COMPLY WITH INDUSTRY
STANDARDS. IN SUCH EVENT, STOP USE IMMEDIATELY
AND CONSULT A DOCTOR.

WARNING NOT FOR PROFESSIONAL USE! Suunto dive computers
are intended for recreational use only. The demands of com-
mercial or professional diving may expose the diver to depths
and conditions that tend to increase the risk of decompression
illness (DCI). Therefore, Suunto strongly recommends that
the device not be used for any commercial or professional
diving activities.
WARNING ONLY DIVERS TRAINED IN PROPER USE OF SCUBA
DIVING EQUIPMENT SHOULD USE A DIVE COMPUTER!
No dive computer can replace the need for proper dive train-
ing. Insufficient or improper training may cause a diver to
commit errors that may lead to serious injury or death.
10
WARNING THERE IS ALWAYS A RISK OF DECOMPRESSION ILLNESS
(DCI) FOR ANY DIVE PROFILE EVEN IF YOU FOLLOW
THE DIVE PLAN PRESCRIBED BY DIVE TABLES OR A
DIVE COMPUTER. NO PROCEDURE, DIVE COMPUTER
OR DIVE TABLE WILL PREVENT THE POSSIBILITY OF
DCI OR OXYGEN TOXICITY! An individual’s physiological
make up can vary from day to day. The dive computer cannot
account for these variations. You are strongly advised to re-
main well within the exposure limits provided by the instrument
to minimize the risk of DCI. As an added measure of safety,
you should consult a physician regarding your fitness before
diving.
WARNING SUUNTO STRONGLY RECOMMENDS THAT SPORT
DIVERS LIMIT THEIR MAXIMUM DEPTH TO 40 M/130 FT
OR TO THE DEPTH CALCULATED BY THE COMPUTER
BASED ON THE SELECTED O2% AND A MAXIMUM PO2
OF 1.4 BAR! Exposure to greater depths increases the risk
of oxygen toxicity and decompression illness.
