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 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
WARNING
10
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 training. Insufficient
or improper training may cause a diver to commit errors that may
lead to serious injury or death.
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
TABLEWILL 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 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 PO2OF 1.4 BAR! Exposure
to greater depths increases the risk of oxygen toxicity and decompression illness.
WARNING
WARNING
WARNING
DIVES WITH REQUIRED DECOMPRESSION STOPS ARE NOT
RECOMMENDED. 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.
USE BACK-UP INSTRUMENTS! Ensure 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.
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, the device has not
run out of battery power, and that the oxygen, altitude, personal,
and Safety/Deep Stop are correct.
11
WARNING
YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FLY TIME. ALWAYS ACTIVATE THE COMPUTER TO CHECK THE REMAINING NO-FLY
TIME PRIOR TO FLYING! Flying or traveling to a higher altitude
within the no-fly time can greatly increase the risk of DCI. Review
the recommendations given by Divers Alert Network (DAN). There
can never be a flying after diving rule that is guaranteed to completely prevent decompression illness!
WARNING
WARNING
12
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
dive, the dive computer 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.
DO NOT EXPOSE ANY PART OF YOUR DIVE COMPUTER 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
THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL
PERCENTAGE VALUES OF OXYGEN CONCENTRATION. DO
NOT ROUND UP FRACTIONAL PERCENTAGES! For example,
31.8% oxygen should be entered as 31%. Rounding up will cause
nitrogen percentages to be understated and will affect decompression calculations. If there is a desire to adjust the computer to
provide more conservative calculations, use the personal adjustment feature to affect decompression calculations or reduce the
PO2setting to affect oxygen exposure according to the entered
O2% and PO2values. As a safety precaution, the oxygen calculations in the dive computer are made with an oxygen percentage
of 1% + set O2%.
WARNING
SET THE CORRECT ALTITUDE ADJUSTMENT MODE! When
diving at altitudes greater than 300 m/1000 ft, the Altitude Adjustment feature must be correctly selected 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. Failure
to select the correct Altitude Adjustment setting or diving above
the maximum altitude limit will result in erroneous dive and planning data.
13
WARNING
SET THE CORRECT PERSONAL ADJUSTMENT MODE!
Whenever it is believed 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 select the
correct Personal Adjustment setting will result in erroneous dive
and planning data.
WARNING
WARNING
14
DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents increase the risk of injury. You should always make the
Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate. If this Mandatory
Safety Stop is not completed the decompression model will penalize your next dive(s).
YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DISPLAYED BY THE INSTRUMENT! The ascent time will increase
if you:
• remain at depth
• ascend slower than 10 m/min / 33 ft/min or
• make your decompression stop deeper than at the ceiling
These factors will also increase the amount of air required to
reach the surface.
WARNING
NEVER ASCEND ABOVE THE CEILING! You must not ascend
above the ceiling during your decompression. In order to avoid
doing so by accident, you should stay somewhat below the ceiling.
WARNING
WARNING
WARNING
DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU
HAVE NOT PERSONALLY 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 information.
Diving with gas mixtures exposes you to risks that are different
from those associated with diving with standard air. These risks
are not obvious, and require training to understand and avoid.
Risks include possible serious injury or death.
Traveling to a higher elevation can temporarily cause a change
in the equilibrium of dissolved nitrogen in the body. It is recommended that you acclimatize to the new altitude by waiting at
least three hours before diving.
15
WARNING
WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE
MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY
TAKE ACTION TO REDUCE OXYGEN EXPOSURE. Failure to
take action to reduce oxygen exposure after the warning is given
can rapidly increase the risk of oxygen toxicity, injury, or death
WARNING
WARNING
WARNING
16
Suunto recommends that you receive training in Free diving
techniques and physiology before conducting breath hold dives.
No dive computer can replace the need for proper dive training.
Insufficient or improper training may cause a diver to commit errors
that may lead to serious injury or death.
If there are several divers using the dive computer with wireless
transmission, always ensure that each diver is using a different
code before starting the dive.
Using the Suunto Dive Planner software is not a substitute for
proper dive training. Diving with mixed gases has dangers that
are not familiar to divers diving with air. To dive with trimix, triox,
heliox and nitrox or all of them, divers must have specialized
training for the type of diving they are doing.
WARNING
Always use realistic SAC rates and conservative turn pressures
during dive planning. Overly optimistic or erroneous gas planning
can result in the exhaustion of breathing gas during decompression or in a cave or a wreck.
WARNING
CAUTION
NOTE
ENSURE THE WATER RESISTANCE OF THE DEVICE! Moisture
inside the device and/or battery compartment may seriously
damage the unit. Only an authorized SUUNTO service center
should do service activities.
Never lift or carry your cylinder by holding the wireless tank
pressure transmitter as this may break the cover and cause
flooding of the unit. If your cylinder falls down with the transmitter
attached to the regulator first stage, ensure that the transmitter
has not been damaged before diving with it.
It is not possible to change to AIR mode after a dive in NITROX
mode, before the No-fly time has elapsed.
When planning both air and nitrox dives during the same dive
series, you should set the instrument in NITROX mode and
modify the gas mix accordingly.

THIS ALSO ACTIVATES THE DIVE MODE.
The water and data transfer contact is located on the side of the case. When submerged, the water contact poles are connected by the conductivity of the water and
the “AC” symbol appears on the display. The AC text is shown until the water contact
deactivates.
Contamination or dirt on the water contact may prevent this automatic activation.
Therefore, it is important that the water contact is kept clean. The contact can be
cleaned with fresh water and a soft brush, for example a tooth brush.
