1. WELCOME TO THE WORLD OF SUUNTO DIVING INSTRU-
MENTS
Suunto D4 was designed to help you get the most out of your diving.
Suunto D4 simplifies your diving experience because all the information you need re-
lating to depth, time and decompression status is available on one easy-to-read screen.
7
To get the most out of your Suunto D4 please read this instruction manual carefully
and make sure you understand the use, displays, and limitations of the instrument
before using it. To make life easier, we've included a glossary of dive-specific termin-
ology at the back of the manual.

2. WARNINGS, CAUTIONS, AND NOTES
Throughout this manual, 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 could
result in serious injury or death
CAUTION is used in connection with a procedure or situation that could
result in damage to the device
NOTE is used to emphasize important information
Before you go on to read the manual itself, it is extremely important that you read the
following warnings. These warnings are intended to maximize your safety while using
Suunto D4 and must not be ignored.
WARNING READ THIS MANUAL! Carefully read this manual in its entirety,
paying close attention to all the warnings listed below, including
Section 5. BEFORE DIVING. Make sure that you fully understand
the use, displays and limitations of the dive computer, because
any confusion resulting from neglecting to follow this user's
manual or from improper use of this device could cause you to
commit errors that may lead to serious injury or death.
9
WARNING NOT FOR PROFESSIONAL USE! Suunto dive computers are
intended for recreational use only. The demands of commercial
or professional diving may expose the diver to depths and condi-
tions that tend to increase the risk of decompression illness (DCI).
Therefore, Suunto strongly recommends that the device is not
used for any commercial or professional diving activities.
WARNING ONLY DIVERS TRAINED IN THE PROPER USE OF SCUBA
DIVING EQUIPMENT SHOULD USE A DIVE COMPUTER! No
dive computer can replace the need for proper dive training. In-
sufficient or improper training may cause you to commit errors
that may lead to serious injury or death.
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 CAN 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 remain well within the exposure limits
provided by the instrument to minimize the risk of DCI. As an
added precaution, you should consult a physician regarding your
fitness before diving.
10
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 PO2OF 1.4 BAR!
WARNING DIVES THAT REQUIRE DECOMPRESSION STOPS ARE NOT
RECOMMENDED. YOU SHOULD ASCEND AND BEGIN DE-
COMPRESSION IMMEDIATELY WHEN THE DIVE COMPUTER
SHOWS YOU THAT A DECOMPRESSION STOP IS REQUIRED!
Note the blinking ASC TIME symbol and the upward pointing ar-
row.
WARNING USE BACK-UP INSTRUMENTS! Make sure that you use back-
up instrumentation, including a depth gauge, submersible pressure
gauge, timer or watch, and have access to decompression tables
whenever diving with the dive computer.
WARNING PERFORM PRE-CHECKS! Always activate and check the device
before diving in order to ensure that all Liquid Crystal Display
(LCD) segments are completely displayed, that the device has
not run out of battery power, and that the oxygen, altitude, person-
al, Safety/Deep Stop, and RGBM adjustments are correct.
