1 SAFETY
Types of safety precautions
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 product.
NOTE: - is used to emphasize important information.
TIP: - is used for extra tips on how to utilize the features and
functions of the device.
Before you dive
Make sure that you fully understand the use, displays and
limitations of your dive instruments. If you have any questions
about this manual or the dive computer, contact your Suunto dealer
before diving with the dive computer. Always remember that YOU
ARE RESPONSIBLE FOR YOUR OWN SAFETY!
5
Safety precautions
WARNING: ONLY TRAINED DIVERS SHOULD USE A DIVE
COMPUTER! Insufficient training for any kind of diving, including
freediving, may cause a diver to commit errors, such as incorrect use
of gas mixtures or improper decompression, that may lead to
serious injury or death.
WARNING: You must read the printed quick guide and online
user guide for your dive computer. Failure to do so may lead to
improper use, serious injury or death.
WARNING: THERE IS ALWAYS A RISK OF DECOMPRESSION
SICKNESS (DCS) 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 DCS 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 DCS. As an added measure of safety, you
should consult a physician regarding your fitness before diving.
WARNING: If you have a pacemaker, we recommend you do not
scuba dive. Scuba diving creates physical stresses on the body which
may not be suitable for pacemakers.
6
WARNING: If you have a pacemaker, consult a doctor before
using this device. The inductive frequency used by the device may
interfere with pacemakers.
WARNING: Allergic reactions or skin irritations may occur 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 commercial or
professional diving may expose the diver to depths and conditions
that tend to increase the risk of decompression sickness (DCS).
Therefore, Suunto strongly recommends that the device not be used
for any commercial or professional diving activities.
WARNING: USE BACKUP INSTRUMENTS! Ensure that you use
backup instrumentation, including a depth gauge, submersible
pressure gauge, timer or watch, and have access to decompression
tables whenever diving with a dive computer.
WARNING:
For safety reasons, you should never dive alone. Dive
with a designated buddy. You should also stay with others for an
extended time after a dive as the onset of possible DCS may be
delayed or triggered by surface activities.
7
WARNING: PERFORM PRE-CHECKS! Always check that your dive
computer is functioning properly and has the correct settings
before diving. Check that the display is working, the battery level is
OK, tank pressure is correct, and so forth.
WARNING: Check your dive computer regularly during a dive. If
there is any apparent malfunction, abort the dive immediately and
safely return to the surface.
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
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.
WARNING: 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.
8
WARNING: DO NOT DIVE WITH A GAS IF YOU HAVE NOT
PERSONALLY VERIFIED ITS CONTENTS AND ENTERED THE
ANALYZED VALUE INTO YOUR DIVE COMPUTER! Failure to verify
tank contents and enter the appropriate gas values where
applicable into your dive computer will result in incorrect dive
planning information.
WARNING: Using a dive planner software such as in Suunto DM5
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: Do not use Suunto USB Cable in areas where
flammable gases are present. Doing so may cause an explosion.
WARNING:
Do not disassemble or remodel Suunto USB Cable in
any way. Doing so may cause an electric shock or fire.
WARNING: Do not use Suunto USB cable if cable or parts are
damaged.
CAUTION:
DO NOT allow the connector pins of the USB cable to
touch any conductive surface. This may short circuit the cable,
making it unusable.
9
Emergency ascents
In the unlikely event that the dive computer malfunctions during a
dive, follow the emergency procedures provided by your certified
dive training agency to immediately and safely ascend.

3 FEATURES
3.1 Activation and pre-checks
Unless the dive mode turned off, the dive mode activates
automatically when you dive deeper than 1.2 m (4 ft). However, you
should switch to dive mode before diving to check altitude and
personal settings, battery condition and so on.
Each time your Suunto D4i enters dive mode, a series of automatic
checks are performed. All graphical display elements are turned ON,
and the backlight and the beep are activated. After this, your
altitude and personal settings are displayed along with the
maximum operating depth (MOD), gas content, and PO2 values.
Then the battery level is checked.

Before leaving on a dive trip, it is highly recommended that you
switch to dive mode to make sure everything is functioning
properly.
16
After the automatic checks, Suunto D4i enters surface mode. At this
point, you should perform your manual checks before entering the
water.
Ensure that:
1. Suunto D4i is in the correct mode and provides complete
displays.
2. Altitude setting is correct.
3. Personal setting is correct.
4. Deepstops are set correctly.
5. Unit system is correct.
6. Correct temperature and depth are shown.
7. The alarm beeps.
3.1.1 Wireless Transmitter pre-check
If the optional wireless tank pressure transmitter is used, check that:
1. Tank gas and O2 settings are correct.
2. The transmitter is properly installed and the tank valve is open.
3. The transmitter and Suunto D4i are paired.
4. The transmitter is sending data (wireless transmission icon blinks,
tank pressure is displayed).
5. There is no transmitter low battery warning.
6. There is enough air for your planned dive. Check the pressure
reading against your back-up pressure gauge.
3.1.2 Battery indicators
Temperature or internal oxidation can affect the battery voltage. If
you store your Suunto D4i for a long period or use it in cold

In these cases, re-enter dive mode and check the battery power. If
the battery is low, the Low Battery warning comes on.
If the low battery icon appears in surface mode, or if the display
looks faded, the battery may be too low. Battery replacement is
recommended.
NOTE:
For safety reasons, the backlight and buzzer (sound)
cannot be activated when the low battery warning is displayed.
