pression 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.
The personal factors which tend to increase the possibility of DCI include, but are
not limited to:
• cold exposure - water temperature less than 20°C [68°F]
• the diver is below average physical tness level
• diver fatigue
• diver dehydration
• previous history of DCI
• stress
• obesity
The Personal Adjustment Mode is indicated by a diver symbol and plus signs
(P0 = a diver, P1 = diver +, or P2 = diver ++). Section 4.2.4. “ Personal Adjustments”
describes how the Personal Mode is adjusted.
This feature should be used to adjust the computer to be more conservative, according
to personal preference, by entering the suitable Personal Adjustment Mode with the help
of Table 3.5. In ideal conditions, retain the default setting, P0. If conditions are more
difcult or other mentioned factors which tend to increase the possibility of DCI exist,
select P1 or even the most conservative P2. As a result the dive computer adjusts its
mathematical model according to the entered Personal Adjustment Mode, giving shorter
no-decompression times (see section 6.1. “Operating Principles”, Table 6.1 and 6.2).
