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.

When programming the instrument for the correct altitude, you need to

select the correct Altitude Mode according to Table 3.4. The dive com-

puter 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 3.4. 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. "Al-

titude 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.

There are adverse personal factors for DCI which divers can predict

in advance and input into the decompression model. Factors that may

affect susceptibility to decompression illness vary between divers and

also for the same diver from one day to another. The three-step Personal

Adjustment Mode is available, if a more conservative dive plan is desired.

For very experienced divers, a two step adjustment for RGBM effect on

repetitive dives is available.

The personal factors which tend to increase the possibility of DCI include,

but are not limited to:
