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.
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).
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.

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 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. 12:00 1.
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.

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).
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).
3.16 Water contact 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 AC 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.
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.
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.
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.
