High Altitude Dives And Personal Adjustment; Altitude Adjustment - Suunto Cobra User Manual

WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE
MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY ASCEND
UNTIL THE WARNING STOPS BLINKING! Failure to take action to reduce
oxygen exposure after the warning is given can rapidly increase the risk of
oxygen toxicity and the risk of injury or death.
3.8. HIGH ALTITUDE DIVES AND PERSONAL
ADJUSTMENT
The dive computer can be adjusted both for diving at altitude and also to increase
the conservatism of the mathematical nitrogen model.

3.8.1. ALTITUDE ADJUSTMENT

When programming the instrument for the correct altitude, you need to select the
correct Altitude Mode according to Table 3.3. The dive computer will adjust its
mathematical model according to the entered altitude mode, giving shorter no-
decompression times at higher altitudes (see Section 6.1. "Operating Principles",
Table 6.1. and 6.2.).
TABLE 3.3. ALTITUDE ADJUSTMENT RANGES
The entered Altitude Adjustment Mode is indicated by mountain symbols (A0, A1
= one mountain, or A2 = two mountains). Section 4.3.1.1. "Altitude Adjustment
and Personal Adjustment Setting" describes how the Altitude Mode is adjusted.
Traveling to a higher elevation can temporarily cause a change in the equilibrium
of dissolved nitrogen in the body. It is recommended that you acclimate to the new
altitude by waiting at least three hours before making a dive.
