Diving At Altitude - Suunto D6 User Manual

5.9.4. Diving at altitude

The dive computer can be adjusted both for diving at altitude and also to increase the
conservatism of the mathematical nitrogen model.
When programming the instrument for the correct altitude, you need to select the
correct Altitude Adjustment settings according to Table 5.5, Altitude Adjustment settings.
The dive computer will adjust its mathematical model according to the entered altitude
setting, giving shorter no-decompression times at higher altitudes (see Table 9.1, No-
decompression time limits for various depths (m) and Table 9.2, No-decompression
time limits for various depths (ft) in Section 9.2. RGBM).

Section 5.8.4. Setting the personal/altitude adjustments describes
how the Altitude value is set.
Traveling to a higher elevation can temporarily cause a change
in the equilibrium of dissolved nitrogen in the body. It is
recommended that you acclimatize to the new altitude by waiting
at least three hours before diving.
