WARNINGS and SAFETY RECOMMENDATIONS relating to ALTITUDE
• Diving at high altitude requires special knowledge of the variations imposed
upon divers, their activities, and their equipment by the decrease in
atmospheric pressures. Oceanic recommends completion of a specialized
Altitude training course by a recognized training agency prior to diving in
high altitude lakes or rivers.
• Altitude compensation provided takes place at 1000 foot (305 meter) intervals
beginning at 3001 feet (916 meters) elevation. Elevation is based upon
samples of Ambient Pressure taken every 30 minutes when the computer
is not activated and every 15 minutes when it is activated. Samples are not
taken and compensation is not provided at any time when the unit is wet.
• When returning to lower altitudes, diving should not be conducted until the
dive computer automatically clears of any residual nitrogen, and oxygen,
loading and resets to operate at the new altitude.
• Repetitive dives in a series should only be conducted at the same Altitude
as that of the rst dive of that series. Repetitive dives made at a different
Altitude will result in an error equal to the difference in barometric pressure,
and possibly a false dive mode with erroneous data.
• If an Oceanic PDC is activated at an elevation higher than 14,000 feet (4,270
meters), it will immediately shutdown or revert to Watch Mode.
