WARNING

Always use realistic SAC rates and conservative turn pressures
during dive planning. An over-optimistic or erroneous gas planning
can result in the exhaustion of breathing gas during decompres-
sion or in a cave or a wreck.

After you finish planning your dive with Suunto Dive Planner, download the gases,
settings and alarms into your dive computer. You can use your Suunto HelO2 to fine-
tune the settings and gases manually.
Always use alternative dive planning methods, such as dive tables, when you plan
the dive. After planning your dive, analyze your dive gases and if they differ substantially
from the planned gases, replan your dive. Also check the lost gas scenarios in case
your decompression gases are altered during a dive, for example, due to a lost cylinder
or a broken valve.

NOTE

For emergency ascents, always print out the dive plan from Suunto
Dive Planner. It ensures that you have a valid decompression
schedule at hand in an unlikely event that the dive computer
malfunctions.

For more information about the warnings, such as Isobaric Counterdiffusion (ICD),
and settings in Suunto Dive Planner, refer to Suunto Dive Planner Help.
