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!

Safety precautions
WARNING: ONLY TRAINED DIVERS SHOULD USE A DIVE
COMPUTER! Insufficient training for any kind of diving may cause a
diver to commit errors 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)! 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
dive. Diving creates physical stresses on the body which may not be
suitable for pacemakers.
WARNING:
using this device. The inductive frequency used by the device may
interfere with pacemakers.
If you have a pacemaker, consult a doctor before
5
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 and a timer or
watch.
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.
WARNING:
PERFORM PRE-CHECKS! Always check that your dive
computer is functioning properly before diving. Check that the
display is working, the battery level is OK, and so forth.
6
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: 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: 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.

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 battery
condition, the display and so on.
Each time your Suunto D4f 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. Then the battery level
is checked.
11
Before leaving on a dive trip, it is highly recommended that you
switch to dive mode to make sure everything is functioning
properly.
After the automatic checks, Suunto D4f enters surface mode. At this
point, you should perform your manual checks before entering the
water.
Ensure that:
1. Suunto D4f is in the correct mode and provides complete
displays.
2. Unit system is correct.
3. Correct temperature and depth are shown.
4. The alarm beeps.
3.2 Alarms, warnings and notifications

field.
If single free dive lasts longer than 10 minutes or if a dive is done in
Gauge mode (bottom timer), the no-fly time is always 48 hours.
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 DCS. 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 sickness!
The Divers Alert Network (DAN) recommends the following on nofly times:
•
A minimum surface interval of 12 hours would be required in
order to be reasonably assured a diver will remain symptom free
upon ascent to altitude in a commercial jetliner (altitude up to
2,400 m (8,000 ft)).
•
Divers who plan to make daily, multiple dives for several days, or
make dives that require decompression stops, should take special
29
precautions and wait for an extended interval beyond 12 hours
before a flight. Further, the Undersea and Hyperbaric Medical
Society (UHMS) suggests divers using standard air cylinders and
exhibiting no symptoms of decompression sickness wait 24 hours
after their last dive to fly in an aircraft with cabin pressure up to
2,400 m (8,000 ft). The only two exceptions to this
recommendation are:
•
If a diver has less than two (2) hours total accumulated dive
time in the last 48 hours, a 12 hour surface interval before
flying is recommended.
•
Following any dive that required a decompression stop, flying
should be delayed for at least 24 hours, and if possible, for 48
hours.
Suunto recommends that flying is avoided until all the DAN and
UHMS guidelines, as well as the dive computer’s no-fly conditions,
are satisfied.

3.16 Water contact
AC
The water contact is located on the side of the case. When
submerged, the water contact poles are connected by the
conductivity of the water. Suunto D4f switches to dive state when
water is detected and the depth gauge senses water pressure at 1.2
m (4 ft).
AC
The
is shown until the water contact deactivates. It is important
to keep the water contact area clean. Contamination or dirt can
prevent automatic activation/deactivation.
NOTE: Moisture build-up around the water contact may cause
the dive mode to activate. This can happen, for example, when
washing your hands or sweating. To save battery power, deactivate
the water contact by cleaning it and/or drying it with a soft towel.

4 CARE AND SUPPORT
4.1 Handling guidelines
The Suunto D4f dive computer is a sophisticated precision
instrument. Although it is designed to withstand the rigors of
diving, you must treat it with the same proper care and caution as
any other precision instrument.
Handle the unit with care – do not knock or drop it.
Do not fasten the strap of your dive computer too tightly. You
should be able to insert your finger between the strap and your
wrist.
After use, rinse it with fresh water, mild soap, and carefully clean
the housing with a moist soft cloth or chamois.
Use only original Suunto accessories - damage caused by nonoriginal accessories is not covered by warranty.
Keep the water contact and depth sensors areas on the sides of the
watch clean using fresh water and a soft brush, such as a
toothbrush.
Never try to open the case of the dive computer. Have your Suunto
D4f serviced every two years by an authorized Suunto service
center.
This service includes a general operational check, replacement of
the battery, and water resistance check. The service requires special
tools and training. Do not attempt to do any servicing yourself.
32
Should moisture appear inside the case or battery compartment,
immediately have the instrument checked by your Suunto service
center.
The optional scratch guard for Suunto D4f is designed to help
prevent the display from getting scratched. Scratch guards can be
purchased separately from your authorized Suunto dealer.
Should you detect scratches, cracks or other such flaws on the
display that may impair its durability, immediately contact your
authorized Suunto dealer.
Protect the unit from shock, extreme heat, direct sunlight, and
chemicals.
Store your dive computer in a dry place when you are not using it.
4.2 Water resistance
Suunto D4f is water resistant to 100 meters (328 ft) in compliance
with the dive watch standard ISO 6425.
To maintain water resistance, it is recommended to:
•
never use the device for other than intended use.
•
contact an authorized Suunto service center, distributor or
retailer for any repairs.
•
keep the device clean from dirt and sand.
•
never attempt to open the case yourself.
•
avoid subjecting the device to rapid air and water temperature
changes.
•
always clean your device with fresh water if subjected to salt
water.
•
never knock or drop the device.
33
4.3 Battery replacement
Suunto D4f displays a battery symbol as a warning when the power
gets too low. When this happens, your Suunto D4f should not be
used for diving until the battery has been replaced.
Contact an authorized Suunto service center for battery
replacement. It is imperative that the change is made in a proper
manner to avoid any leakage of water into the battery
compartment or computer.
Defects caused by improper battery installation are not covered by
the warranty.
All history and logbook data, as well as the altitude, personal and
alarm settings, remain in the dive computer memory after the
battery change. Other settings revert back to default values.
