CE
The CE mark is used to mark conformity with the European Union EMC directive 89/
336/EEC and Personal Protective Equipment directive 89/686/EEC. The SUUNTO di-
ve instruments fulfill all the required EU directives.
FIOH, Laajaniityntie 1, FIN-01620 Vantaa, Finland, notified body no.0430, has EC ty-
pe-examined this type of personal protective equipment.
EN 250 Respiratory equipment - Open circuit self-contained compressed air diving ap-
paratus – Requirements, testing, marking.
The cylinder pressure gauge and the parts of this product used in measuring the cylin-
der pressure meet the requirements set in the section of the European Standard EN
250 that concern cylinder pressure measurements. The instruments must be serviced
by an authorized dealer every second year or after 200 dives (whichever comes first).
EN 13319
EN 13319 ”Diving accessories – Depth gauges and combined depth and time measu-
ring devices – Functional and safety requirements, test methods” is a European diving
depth gauge standard. The D9 is designed to comply with this standard.
ISO 9001
SUUNTO Oy’s Quality Assurance System is certified by Det Norske Veritas to be ac-
cording to the ISO 9001 in all SUUNTO Oy’s operations (Quality Certificate No. 96-

WARNING!
READ THIS MANUAL! Carefully read this instruction manual in its entirety pay-
ing close attention to all warnings listed below, including section 1.1. ”Safety Pre-
cautions”. Make sure that you fully understand the use, displays and limitations of
the dive computer because any confusion resulting from neglecting to follow this
instruction manual or from improper use of this device may cause a diver to com-
mit errors that may lead to serious injury or death.
WARNING!
This product contains a Lithium cell battery. To reduce risk of fire or burns, do not
disassemble, crush, puncture, short external contacts, or dispose of in fire or wa-
ter. Replace only with manufacturer specified batteries. Recycle or dispose of us-
ed batteries properly.
WARNING!
NOT FOR PROFESSIONAL USE! Suunto dive computers are intended for recrea-
tional use only. The demands of commercial or professional diving may expose the
diver to depths and exposures that tend to increase the risk of decompression ill-
ness (DCI). Therefore, Suunto strongly recommends that the device be not used
for commercial or professional diving activity.

5
WARNING!
ONLY DIVERS TRAINED IN THE PROPER USE OF SCUBA DIVING EQUIP-
MENT SHOULD USE A DIVE COMPUTER! No dive computer can replace the
need for proper dive training. Insufficient or improper training may cause diver 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 DI-
VE TABLES OR A DIVE COMPUTER. NO PROCEDURE, DIVE COMPUTER OR
DIVE TABLE WILL PREVENT THE POSSIBILITY OF DCI OR OXYGEN TOXICI-
TY! An individual’s physiological make up can vary from day to day. The dive com-
puter 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 measure of safety, you should consult a physician regarding your fit-
ness before diving.
WARNING!
SUUNTO STRONGLY RECOMMENDS THAT SPORT DIVERS LIMIT THEIR MA-
XIMUM 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!

6
WARNING!
DIVES WITH REQUIRED DECOMPRESSION STOPS ARE NOT RECOMMEN-
DED. YOU SHOULD ASCEND AND BEGIN DECOMPRESSION IMMEDIATELY
WHEN THE DIVE COMPUTER SHOWS YOU THAT A DECOMPRESSION STOP
IS REQUIRED! Note the blinking ASC TIME symbol and the upward pointing arrow.
WARNING!
USE BACK-UP INSTRUMENTS! Make sure that you use back-up instrumentati-
on including a depth gauge, submersible pressure gauge, timer or watch, and have
access to decompression tables whenever diving with the dive computer.
WARNING!
PERFORM PRECHECKS! 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, al-
titude, personal, safety/deepstop and RGBM adjustments are correct.
WARNING!
YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS
DOWN THE NO-FLYING TIME. ALWAYS ACTIVATE THE COMPUTER TO
CHECK THE REMAINING NO-FLY TIME PRIOR TO FLYING! Flying or trave-
ling to a higher altitude within no-fly time can greatly increase the risk of DCI. Re-
view the recommendations given by Diver’s Alert Network (DAN) in chapter 6.5.4
“Flying After Diving”.

WARNING!
THE DIVE COMPUTER SHOULD NEVER BE TRADED OR SHARED BETWEEN
USERS WHILE IT IS IN OPERATION! Its information will not apply to someone
who has not been wearing it throughout a dive or sequence of repetitive dives. Its
dive profiles must match that of the user. If it is left on the surface during any di-
ve, it will give inaccurate information for subsequent dives. No dive computer can
take into account dives made without the computer. Thus any diving activity up to
four days prior to initial use of the computer may cause misleading information and
must be avoided.
WARNING!
DO NOT EXPOSE THE D9´S OPTIONAL PRESSURE TRANSMITTER TO ANY
GAS MIX CONTAINING MORE THAN 40% OXYGEN! Enriched air with greater
oxygen content presents a risk of fire or explosion and serious injury or death.
WARNING!
DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU HAVE NOT PER-
SONALLY VERIFIED ITS CONTENTS AND ENTERED THE ANALYZED VALUE
INTO YOUR DIVE COMPUTER! Failure to verify cylinder contents and enter the
appropriate O2% into your dive computer will result in incorrect dive planning infor-
mation.

8
WARNING!
THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL PERCENTAGE VA-
LUES OF OXYGEN CONCENTRATION. DO NOT ROUND UP FRACTIONAL
PERCENTAGES! For example, 31.8% oxygen should be entered as 31%. Roun-
ding up will cause nitrogen percentages to be understated and will affect decom-
pression calculations. If there is a desire to adjust the computer to provide more
conservative calculations, use the personal adjustment feature to affect decom-
pression calculations or reduce the PO2setting to affect oxygen exposure.
WARNING!
SET THE CORRECT ALTITUDE ADJUSTMENT MODE! When diving at altitudes
greater than 300 m [1000 ft] the Altitude Adjustment feature must be correctly se-
lected in order for the computer to calculate the decompression status. The dive
computer is not intended for use at altitudes greater than 3000 m [10000 ft]. Fai-
lure to select the correct Altitude Adjustment setting or diving above the maximum
altitude limit will result in erroneous dive and planning data.
WARNING!
SET THE CORRECT PERSONAL ADJUSTMENT MODE! Whenever it is belie-
ved that factors that tend to increase the possibility of DCI exist, it is recommended
that you use this option to make the calculations more conservative. Failure to se-
lect the correct Personal Adjustment setting will result in erroneous dive and plan-
ning data.
