The STOP sign will appear in the display and when
you reach the depth zone between 6 m to 3 m [20 ft
to 10] also the CEILING label, ceiling depth and the
calculated Safety Stop time appear in the display. You
should wait until the Mandatory Safety Stop warning
disappears (Fig. 3.13.).
The Mandatory Safety Stop time always includes the
three minute Recommended Safety Stop time. The total
length of the Mandatory Safety Stop time depends on
the seriousness of the ascent rate violation.
You must not ascend shallower than 3 m [10 ft] with
the Mandatory Safety Stop warning on. If you ascend
above the Mandatory Safety Stop ceiling, a downward
pointing arrow will appear and a continuous beeping
starts (Fig. 3.14.). You should immediately descend to,
or below, the Mandatory Safety Stop ceiling depth. If
you correct this situation at any time during that dive,
there are no affects on the decompression calculations
for future dives.
If you continue to violate the Mandatory Safety Stop,
the tissue calculation model is af fected and the di ve
computer shortens the a vailable no-decompression
time for your next dive. In this situation, it is recom-
mended to prolong your surf ace interval time before
your next dive.
3.3. DIVING WITH THE GEKKO
The GEKKO has two operating modes: Air mode for
diving with standard air only and Nitrox mode for div-
ing with oxygen enriched (EANx) mixtures. The Ni-
trox mode is enabled in the MODE-SET-MODEL.
3.3.1. Basic Dive Data
The dive computer will remain in the Surface mode at
depths less than 1.2 m [4 feet]. At depths greater than
1.2 m the instrument will go into the Di ving mode
(Fig. 3.6.).

Present depth is 19.3 m [63
ft] and no-decompression
stop time limit is 23 minutes
in A0/P1 mode. Maximum
depth during this dive
was 19.8 m [65 ft], water
temperature is 18¡ C [64¡F],
elapsed dive time is 16
minutes. Alternative display
of current time 10:20 [10:20
am] is shown for 5 seconds
after pressing TIME button.
