ALTITUDE DIVING
The atmospheric pressure is lower at high altitudes than at sea level. After traveling
to a higher altitude, the diver will have additional nitrogen in his body, compared
to the equilibrium situation at the original altitude. This "additional" nitrogen is
released gradually in time and equilibrium is reached. It is recommended that
you acclimate to the new altitude by waiting at least three hours before making
a dive.
Before high altitude diving, the instrument must be set to the Altitude Adjustment
mode to adjust the calculations for the new altitude. The maximum partial pres-
sures of nitrogen allowed by the mathematical model of the dive computer are
reduced according to the lower ambient pressure.
As a result, the allowed no-decompression stop limits are considerably reduced.
SURFACE INTERVALS
The dive computer requires a minimum surface interval of 5 minutes between
dives. If a surface interval is shorter than 5 minutes, the next dive is treated as a
continuation of the previous dive.
