Safety Precautions; Emergency Ascents; Dive Computer Limitations - Suunto Cobra User Manual

1.1. SAFETY PRECAUTIONS

Do not attempt to use the dive computer without reading this instruction manual
in its entirety, including all the warnings. Make sure that you fully understand the
use, displays and limitations of the instrument. If you have any questions about
the 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!
When used properly, the dive computer is an outstanding tool for assisting
properly trained, certifi ed divers in planning and executing sport dives. It is NOT
A SUBSTITUTE FOR CERTIFIED SCUBA INSTRUCTION, including training
in the principles of decompression.
Diving with enriched air mixtures (nitrox) exposes the user to risks 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.
Do not attempt to dive with any gas mix other than standard air without fi rst
receiving certifi ed training in this specialty.

1.1.1. EMERGENCY ASCENTS

In the unlikely event that the dive computer 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.

1.1.2. DIVE COMPUTER LIMITATIONS

While the dive computer is based on current decompression research and technology,
you must realize that the computer cannot monitor the actual physiological functions
of an individual diver. All decompression schedules currently known to the authors,
including the U.S. Navy Tables, are based on theoretical mathematical models,
which are intended to serve as a guide to reduce the probability of decompression
illness.
