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.

WARNING!

SET THE CORRECT ALTITUDE ADJUSTMENT MODE! When diving at

altitudes greater than 300 m [1000 ft] the Altitude Adjustment feature must

be correctly selected in order for the computer to calculate no-decompression

status. Failure to properly select the Altitude Adjustment Mode correctly will

result in erroneous data and can greatly increase the risk of DCS.

WARNING!

THIS DIVE COMPUTER IS NOT INTENDED FOR USE AT ALTITUDES

GREATER THAN 3000 m [10000 ft]! Diving at altitudes above this limit may

signiﬁ cantly increase the risk of DCS.

Traveling to a higher elevation can temporarily cause a change in the equilibrium

of dissolved nitrogen in the body with the surroundings. It is recommended that

you allow the body conditions to stabilize over a period of at least three hours

before beginning to dive at altitude.

3.7.2. Personal Adjustment

Factors that may affect susceptibility to decompression sickness 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.

The factors which tend to increase the possibility of DCS include, but are not

limited to:

• cold exposure - water temperature less than 20 °C [68 °F]

• the diver is below average physical ﬁ tness level

• multiday or repetitive dive exposure

• diver fatigues

• diver dehydration

• previous history of DCS.
