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.
3.7.2. Personal Adjustment
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.
The personal factors which tend to increase the possibility of DCI include, b ut
are not limited to:
- cold exposure - water temperature less than 20 ¡C [68 ¡F]
- the diver is below average physical fi 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 conserv
ative,
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 diffi cult or other mentioned factors which tend to increase
the possibility of DCI e xist, select P1 or e ven the most conserv ative 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).
