SUUNTO VYTEC DS - Manual (Page 11)

9
In order to optimize how to respond to different added risk situations an
additional category of stop, referred to as a Mandatory Safety Stop, has
been introduced. Also a countdown for the Recommended Safety Stop
is included. The combination of stop types will depend on the specifi c
dive situation.
To get the most from the safety benefi ts be sure to read the summary
of the Reduced.
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 in-
clude 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.
