WHEN ENTERING THE PLANNODEC MODE THE DISPLAY FIRST BRIEFLY
SHOWS THE REMAINING DESATURATION TIME BEFORE GOING INTO PLAN MODE. USE UP
AND DOWN BUTTONS TO SCROLL DIFFERENT NO-DECOMPRESSION LIMITS.
NO-DECOMPRESSION LIMITS LONGER THAN 99 MINUTES ARE DISPLAYED AS “–”.
The Planning mode takes into account the following information from previous dives:
•
•
any calculated residual inert gas
•
all dive history for the past four days
The no-decompression times given for different depths will therefore be shorter than before
your first “fresh” dive.
You can exit the planning mode by pressing the MODE button.

NOTE
The Planning mode is disabled in GAUGE mode and in Error mode
(see Section 5.7. Error conditions). The planning mode calculates no-
decompression times for MIX1 only. If an additional mix is enabled
in the MIXED GAS mode, it does not affect the calculations in
PLANNoDec mode.

Higher Altitude and conservative Personal Adjustment settings will shorten the no-decom-
pression time limits. These limits at different Altitude and Personal Adjustment setting
selections are explained in Section 5.10.4. Diving at altitude and in Section 5.10.5. Personal

Dive numbering shown during dive planning
Dives belong to the same repetitive dive series if the instrument was still counting down
the no-fly time at the beginning of the dive.
The surface interval must be at least 5 minutes for a dive to be considered a repetitive
dive. Otherwise, it is considered a continuation of the same dive. The dive number will not
change and the dive time will continue where it left off. (See also Section 7.2. Dive num-
bering ).
