or the freediving computer, contact your SUUNTO dealer before diving with 
the D3.

Always remember that you are responsible for your own safety.
When used properly, this freediving computer is an outstanding tool for assisting 
properly trained, certifi ed divers in planning and executing sport dives. It is not 
a substitute for certifi ed scuba instruction or freediving training.

In the unlikely event that D3 malfunctions during a dive, follow the emergency 
procedures provided by your certifi ed dive training agency or, alternatively, 
STEP 1:   Assess the situation calmly and then move promptly to less than 18 m 

[60 ft].

STEP 2:   At 18 m [60 ft], slow down your ascent rate to 10 m/min [33 ft/min] 

and move to a depth between 3 and 6 meters [10 to 20 ft].

STEP 3:   Stay there as long as you assess your air supply will safely allow. After 

reaching the surface stay out of the water for at least 24 hours.

Freediving, and particularly freediving in combination with scuba diving, may 
have risks that have not been researched and are not commonly known.
