Display at the ceiling zone
When you reach the ceiling zone, the display will show you two arrows pointing at
each other (the “hour glass” icon). Below is an example of a decompression dive at
the ceiling zone.
TWO ARROWS POINT AT EACH OTHER
“HOUR GLASS”. YOU ARE IN THE OPTIMUM CEILING
ZONE AT 3 M. AND YOUR MINIMUM ASCENT TIME IS
8 MINUTES.
During the decompression stop, ASC TIME will count down towards zero. When the
ceiling moves upwards,you canascend tothe newceiling. You may surfaceonly after
the ASC TIME and CEILING labels have disappeared, which means that the
decompression stop and any Mandatory Safety Stop have been completed. You are
advised, however, to stay until the STOP sign has also disappeared. This indicates
that the three minute Recommended Safety Stop has also been completed.
Display above the ceiling
If you ascend above the ceiling during a decompression stop, a downward pointing
arrow will appear and a continuous beeping starts.
