Section 5.2.4. ”Altitude Adjustment and Personal Adjustment
Setting” describes how the Personal Mode is adjusted.

This feature should be used to adjust the computer to be mo-
re conservative, according to personal preference, by ente-
ring the suitable Personal Adjustment Mode with the help of
Table 5.2. 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 exist, select P1 or even
the most conservative P2. As a result the dive computer ad-
justs its mathematical model according to the entered Perso-
nal Adjustment Mode, giving shorter no-decompression times
(see Section 10.2, Table 10.1. and 10.2.).
