WARNING | NEVER ASCEND ABOVE THE CEILING! You must not ascend above |
| the ceiling during your decompression. In order to avoid doing so by |
| accident, you should stay somewhat below the ceiling. |
Display below the floor
The blinking ASC TIME and an upward pointing arrow indicate that you are below the floor. The ceiling depth is shown on the left side, and the minimum total ascent time on the right side, of the center window. Below is an example of a decompression dive above Deep Stops, below the floor.
UPWARD POINTING ARROW, BLINKING ASC
TIME AND AN ALARM TELL YOU TO ASCEND. MINIMUM
TOTAL ASCENT TIME INCLUDING MANDATORY SAFETY
STOP IS 15 MINUTES. CEILING IS AT 3 M.
Display above the floor
When you ascend above the floor, the ASC TIME display stops blinking and the upward pointing arrow disappears. Below is an example of a decompression dive above the floor.
UPWARD POINTING ARROW HAS
DISAPPEARED AND ASC TIME LABEL HAS
STOPPED BLINKING, MEANING YOU ARE IN
THE DECOMPRESSION RANGE.
Decompression will now begin, but is very slow. You should therefore continue your ascent.
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 15 MINUTES.
During the decompression stop, ASC TIME will count down towards zero. When the ceiling moves upwards, you can ascend to the new ceiling. You may surface only 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 Recommen- ded 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.
